Every fridge on this page wants to be the energy efficient one. The words are everywhere: “Energy Efficient & Cost Effective”, “Energy Conservation”, “Quiet & Efficient”, “Energy Saving”. A word costs a seller nothing. Two things on a listing actually let you check the claim: an ENERGY STAR certification, or a stated figure for how many kilowatt-hours the fridge uses. So we counted both.
Five of the ten state ENERGY STAR certification. All three Midea models say it in their titles, BLACK+DECKER says it in its title and a bullet, and Upstreman says it in a bullet. Seven of the ten print a kWh figure. The three Midea listings give annual figures, 207, 255 and 270 kWh a year. Four others give daily figures: Cucina Magica 0.5 kWh, Feelfunn 0.55 kWh, Frostorm 0.6 kWh and EUHOMY “as low as 0.66 kWh per day”.
Only three listings give you both, and they are all Midea. BLACK+DECKER and Upstreman claim the certification and print no kWh. The four daily-figure listings print a number and claim no certification. And one listing has neither: the Frigidaire retro fridge puts “Energy Saving” in its title and never backs it with a label, a kWh figure or even a wattage. On the evidence of its own listing, that is an unverified claim.
The kWh figures sit in a narrow band. Turned into annual figures where needed, which is our arithmetic, the seven run from about 182.5 kWh a year on the Cucina Magica to 270 kWh a year on the Midea 3.1. The capacities behind them run from 1.6 to 3.2 cubic feet. A fridge twice the size does not use twice the power, which is why the fairer comparison is kWh per cubic foot.
Divide each stated figure by the stated capacity, which is again our arithmetic, and the order changes. The Cucina Magica comes out at about 62.9 kWh per cubic foot per year, the EUHOMY at about 75.3, the Midea 3.1 at about 87.1 and the Midea 2.7 at about 94.4. The small fridges come last: the Feelfunn at about 118.1, the Midea 1.6 at about 129.4 and the Frostorm at about 136.9. But the two lowest figures are seller claims with no certification behind them, and one of them says “as low as”. Among the fridges that pair a kWh figure with a certification, the Midea 3.1 with a true freezer is the most efficient per cubic foot.
And the best sellers are not the best documented. The Frostorm sits at #18 overall on Amazon and #1 in Upright Freezers, the best rank on the page, with a daily kWh claim and no certification. BLACK+DECKER is second at #110 with a certification and no kWh. Cucina Magica is third at #171 with a kWh claim and no certification. None of the top three gives both. The three Midea listings that do sit between #7,000 and #9,826 overall.
So this guide sorts the ten by the evidence each listing gives for its efficiency: certification and kWh together, certification alone, kWh alone, and neither. Every fridge here is a compressor model. Thermoelectric personal fridges, the small cooler-style boxes, are as a rule far less efficient than compressor units, and none made this list. We print no electricity costs, only kWh, and every per-cubic-foot figure is labelled as ours. Star ratings and review counts were not captured for this roundup; popularity below is Amazon’s Best Sellers Rank only.
All ten were captured on 5 October 2026. Their overall Best Sellers Ranks run from #18 to #13,581, and the three listings with both a certification and a kWh figure sit at #7,000, #9,067 and #9,826.

Best Sellers Ranks and specifications are taken from each manufacturer’s Amazon listing as displayed on 5 October 2026 through a United States connection, and may change. Every kWh figure is quoted as the listing gives it. The three Midea figures are annual; the Cucina Magica, Feelfunn, Frostorm and EUHOMY figures are daily, and none of those four says how or at what setting it was measured. Wherever this page converts a daily figure to a year, or divides by capacity, that is our arithmetic. BLACK+DECKER states 70 watts, which is a power draw, not an energy use, and cannot be turned into kWh without knowing how long the compressor runs. ENERGY STAR status is as stated in each listing; we did not look the models up in the ENERGY STAR database, and the model numbers are given in the detail cards so you can. Ranks are overall Best Sellers Ranks as returned on 5 October 2026, and Amazon files these ten in four different categories. Six were sold by Amazon.com at capture, the other four by their brands or brand-linked sellers. The EUHOMY was flagged as scarce stock. Star ratings and review counts were not captured for any product here, and no electricity costs are printed anywhere on this page.

How We Chose These Ten
We researched current listings, compared manufacturer specifications and documentation, and read every efficiency claim on each listing line by line. We did not carry out hands-on testing, and nothing below is presented as measured performance data. Star ratings and review counts were not captured for this roundup. We used Amazon Best Sellers Rank, buy-box stock and listing specifications instead, and nothing on this page describes or implies how owners have scored these fridges.
- Compact compressor fridges only — every fridge here is a plug-in compact refrigerator between 1.6 and 3.2 cubic feet, with or without a freezer section. Thermoelectric personal coolers, 12-volt car fridges and full-size refrigerators were not in the running.
- Certification recorded where the listing states it — a fridge counts as ENERGY STAR on this page only if its title or bullets say so. We record where the claim appears. We did not verify any model against the ENERGY STAR product database, and we tell you how to do that yourself.
- kWh recorded exactly as printed — annual where the listing gives a year, daily where it gives a day, with qualifiers such as “as low as” and “average” kept. A wattage is recorded as a wattage, never converted into energy use.
- Per-cubic-foot figures are ours — where a listing gives both a kWh figure and a capacity, we converted the daily figures to a year at 365 days and divided by the stated capacity. Every such figure is labelled as our arithmetic. No figure was estimated for a listing that gives no kWh.
- “Energy saving” without evidence is marked unverified — a listing that uses efficiency language with neither a certification nor a kWh figure is reported as making a claim it does not support.
- No electricity costs — two listings estimate a daily running cost. We do not reprint those, or any cost of our own; tariffs vary, and kWh is the number you can compare.
- Popularity from Best Sellers Rank only — ranks are quoted exactly as returned on 5 October 2026, overall and in the category Amazon assigned. Amazon files these ten under Compact Refrigerators, Freezers, Upright Freezers and Standard Refrigerators, so category ranks do not compare across all ten.
- Verified stock and seller — each product was the buy-box offer and in stock on amazon.com on 5 October 2026. The EUHOMY was flagged as scarce stock at capture.
The Ten Mini Fridges in Detail
1. Midea 3.1 Cu Ft Mini Fridge with Freezer, ENERGY STAR, WHD-113FSS1 — Best Overall
A certification, an annual kWh figure and a true freezer, and the lowest kWh per cubic foot of the three listings that give both.
Key Specifications
| ENERGY STAR | Stated in title; “E-Star Certificated” in bullet |
|---|---|
| Energy use | 270 kWh/year, stated |
| kWh per cu ft (ours) | About 87.1 per year |
| Capacity | 3.1 cu ft (fridge 2.16, freezer 0.92) |
| Fridge range | 32–50°F |
| Freezer range | -11.2°F to 5°F |
| Refrigerant | R600a |
| Size (W x D x H) | 18.5 x 19.37 x 32.95 in |
| Noise | Not stated |
| Warranty | Full 1-year; compressor 2-year |
| Seller | Amazon.com |
| Best Sellers Rank | #9,826 overall; #20 in Compact Refrigerators |
Why We Recommend It
This listing gives you both pieces of evidence, and the better ratio of the three that do. The title says “Energy Star Certified”. A bullet adds the number: “This mini fridge uses R600A high-efficiency compressor, only 270Kwh/Y energy consumption.” 270 kWh a year is the highest annual figure on the page in raw terms. Spread over 3.1 cubic feet, it is about 87.1 kWh per cubic foot per year, by our arithmetic. The Midea 2.7 comes out at about 94.4 and the Midea 1.6 at about 129.4. Of the three listings that pair a certification with a kWh figure, this one stores the most for each unit of energy.
It does that with a real freezer. The capacity splits into “Freezer 0.92 cu.ft, fridge 2.16 cu.ft”, and the freezer is set at “-11.2℉ to 5℉(-24℃ to -15℃)”. Holding a compartment that cold costs energy. One fridge on this page has a freezer section its own listing says will not hold ice cream, and another has a micro-freezer that tops out at 41°F; this one gives a range that will. That makes its kWh figure more impressive, not less: the 270 kWh covers a working freezer as well as the fridge.
A daily view helps when comparing it with the seller figures. 270 kWh over 365 days is about 0.74 kWh a day, by our arithmetic. That is more than the four daily claims on the page, which run from 0.5 to 0.66 kWh a day, but those four come without a certification, and the Midea’s figure ties to a label you can look up by model number, WHD-113FSS1. The two fridge sections are also different sizes: the closest uncertified rivals in capacity are the Cucina Magica, with 2.9 cubic feet and a 0.8 cubic foot freezer, and the EUHOMY, with 3.2 cubic feet and a micro-freezer the listing sets at 23–41°F.
The fridge section is conventional and well equipped. The thermostat is mechanical, with a fridge range of “32℉-50.0℉(1℃-10℃)”. There is a “Multi-air flow system”, LED interior lighting, detachable glass shelves, a crisper drawer and a 2-litre bottle rack. The listing pitches it as “Roomy for a tiny house”, which at just over three cubic feet is a stretch, but it is the largest certified fridge on the page that also states its energy use.
The size and the silence are the trade-offs. At 18.5 by 19.37 by 32.95 inches and 52.24 pounds listed, it is the heaviest fridge here and one of the tallest, so it is a floor-standing unit, not one for a desk. It gives no noise figure, while six other listings print a decibel number; if the fridge will sit in a bedroom, read our quiet mini fridge roundup first.
What to weigh. It is sold by Amazon.com and ranks #9,826 overall and #20 in Compact Refrigerators, the lowest rank of the three Midea listings. The warranty is “Full 1-Year / Compressor 2-Year”, longer on the compressor than any listing outside the Midea range. If you want proof of efficiency and a freezer that freezes, this is the strongest combination on the page.
Pros
- ENERGY STAR and 270 kWh/year both stated
- About 87.1 kWh per cu ft by our arithmetic, best of the certified three
- True freezer, -11.2°F to 5°F
- R600a refrigerant, stated
- 2-year compressor warranty
- Sold by Amazon.com
Cons
- Highest raw annual figure on the page
- No noise figure
- 52.24 lb listed, the heaviest here
- 32.95 in tall; not a desk fridge
- Lowest rank of the three Midea listings
- Mechanical thermostat, no display
Best for: A buyer who wants a certified, kWh-stated fridge with a freezer that holds ice cream, and has floor space for it.
2. Midea 1.6 Cu Ft Mini Fridge, ENERGY STAR, WHS-65LB1 — Best Compact
The lowest annual figure behind a certification on the page, 207 kWh a year, in a fridge small enough for a desk.
Key Specifications
| ENERGY STAR | Stated in title; “E-Star Certificated” in bullet |
|---|---|
| Energy use | 207 kWh/year, stated |
| kWh per cu ft (ours) | About 129.4 per year |
| Capacity | 1.6 cu ft |
| Thermostat range | 28.4–35.6°F (-2 to 2°C) |
| Freezer | None stated; chiller box |
| Refrigerant | R600a |
| Size (W x D x H) | 18.6 x 17.7 x 19.4 in (bullet); height 18.19 in (spec table) |
| Noise | Less than 42 dB, stated |
| Warranty | Full 1-year; compressor 2-year |
| Seller | Amazon.com |
| Best Sellers Rank | #9,067 overall; #18 in Compact Refrigerators |
Why We Recommend It
If you want the smallest certified number, this is it. The title says “Energy Star Certified”, and the bullet reads: “This mini fridge uses R600A high-efficiency compressor, only 207 Kwh/Y energy consumption, which is energy-saving.” 207 kWh a year is the lowest annual figure on the page that comes with a certification. Over 365 days it is about 0.57 kWh a day, by our arithmetic, which sits in the same range as the uncertified daily claims from Feelfunn, 0.55, and Frostorm, 0.6.
Per cubic foot, small fridges lose, and this one is no exception. 207 kWh over 1.6 cubic feet is about 129.4 kWh per cubic foot per year, by our arithmetic, against about 87.1 for the Midea 3.1. That is not a fault in the fridge; it is how compact refrigerators behave. The compressor, the door seal and the insulation have to work whatever the volume, so halving the box does not halve the energy. If what you need is small, the right comparison is with the other small fridges, and here the Midea 1.6 beats the Frostorm’s about 136.9, by our arithmetic, and trails the Feelfunn’s about 118.1. The Feelfunn’s figure, though, is a seller claim with no certification.
The thermostat range is unusually narrow and cold. The listing says the controls hold “optimum temperature from 28.4℉ to 35.6℉”. Most fridges here run up to 50°F. A range that starts below freezing suits drinks and dairy kept very cold, but it means there is no warm setting for produce that dislikes the cold, and the coldest end will cost more energy than the middle. The “chiller box inside can cool your drinks faster”; it is not described as a freezer, and no freezer temperature is given.
Two height figures appear, and both suit a desk. The bullet gives “18.6*17.7*19.4 inches(W*D*H)”; the spec table gives 18.19 inches tall. Plan for 19.4. Either way it is a cube that sits under most desks, with a reversible door, one removable glass shelf and a 2-litre bottle rack. For more on fridges at this size, see our 1.6 cu ft mini fridge roundup.
It states a noise ceiling. “Less than 42dB noise level” is the highest decibel figure on the page, so it is not the quietest choice, but it is a number, which the Midea 2.7, Midea 3.1, BLACK+DECKER and Frigidaire do not give.
What to weigh. It is sold by Amazon.com and ranks #9,067 overall and #18 in Compact Refrigerators. The release date field says 2017, so this is a long-running model, and the warranty is “Full 1-Year / Compressor 2-Year”. You can check its certification by model number, WHS-65LB1. For a desk-sized fridge with proof of efficiency, nothing on this page is better documented.
Pros
- ENERGY STAR and 207 kWh/year both stated
- Lowest certified annual figure here
- Desk-sized cube
- Noise stated, under 42 dB
- 2-year compressor warranty
- Sold by Amazon.com
Cons
- About 129.4 kWh per cu ft by our arithmetic
- Thermostat only 28.4–35.6°F
- No freezer, only a chiller box
- Two different heights listed
- Highest stated decibel figure here
- One shelf
Best for: A buyer who wants the smallest certified annual figure in a fridge that fits under a desk.
3. Midea 2.7 Cu Ft Mini Fridge, ENERGY STAR, MERM26B0ABB — Best Mid-Size
Certified, kWh stated and the best-ranked of the three Midea listings, with no freezer to pay for.
Key Specifications
| ENERGY STAR | Stated in title and first bullet |
|---|---|
| Energy use | 255 kWh/year, stated |
| kWh per cu ft (ours) | About 94.4 per year |
| Capacity | 2.7 cu ft |
| Thermostat range | 33.8–50.0°F |
| Freezer | Not stated |
| Size (D x W x H) | 17.6 x 18.6 x 27.4 in |
| Listed weight | 35.9 pounds |
| Noise | “Low Noise” in title; no figure |
| Warranty | 1 year |
| Seller | Amazon.com |
| Best Sellers Rank | #7,000 overall; #13 in Compact Refrigerators |
Why We Recommend It
The first bullet is the efficiency case, made properly. “ENERGY STAR Certified: Meets government energy efficiency standards and only 255 Kwh/Y energy consumption.” A certification and a number, in the first line a buyer reads. Of the ten listings, only the three Midea models manage that, and the model number, MERM26B0ABB, lets you check it.
The ratio sits between its two siblings. 255 kWh over 2.7 cubic feet is about 94.4 kWh per cubic foot per year, by our arithmetic, better than the Midea 1.6 at about 129.4 and a little behind the Midea 3.1 at about 87.1. In daily terms 255 kWh is about 0.70 kWh a day, by our arithmetic. The Midea 3.1 adds 0.4 cubic feet and a true freezer for 15 kWh more a year, which is why it edges this one on the ratio.
No freezer is stated, and that is a choice worth making on purpose. The bullets describe a fridge: a temperature range of “33.8°F to 50.0°F”, a “multi-airflow circulation system”, a door shelf that “holds a 2-liter bottle” and a can rack that “holds up to 6 cans”. If you never make ice, a fridge-only box avoids running a cold compartment you do not use. Our mini fridge without freezer guide covers that choice in more depth.
The size is mid-height. 17.6 by 18.6 by 27.4 inches puts it above desk height for most, but under a worktop, at 35.9 pounds listed. The door is reversible. The title promises “Low Noise for Office”, but no decibel figure appears anywhere on the listing, so treat that as a word like any other.
What to weigh. It is sold by Amazon.com and ranks #7,000 overall and #13 in Compact Refrigerators, the best rank of the three listings with both a certification and a kWh figure. The warranty is a plain 1 year, without the 2-year compressor cover the other two Midea listings state. For a fridge-only unit with full documentation, it is the one to beat.
Pros
- ENERGY STAR and 255 kWh/year in the first bullet
- About 94.4 kWh per cu ft by our arithmetic
- Best rank of the three fully documented fridges
- 33.8–50°F range
- Can rack and 2-litre door shelf
- Sold by Amazon.com
Cons
- No freezer stated
- “Low Noise” with no decibel figure
- 1-year warranty only, no compressor extension
- 27.4 in tall; not a desk fridge
- Slightly worse ratio than the Midea 3.1
- Shelf count not stated
Best for: A buyer who wants a certified, kWh-stated fridge without a freezer, sized for an office or bedroom corner.
4. BLACK+DECKER 1.7 Cu Ft Compact Refrigerator, ENERGY STAR, BCRK17B — Most Popular Energy Star
The best-selling certified fridge on the page, and it gives you watts instead of kWh.
Key Specifications
| ENERGY STAR | Stated in title and bullet |
|---|---|
| Energy use | Not stated in kWh; “minimal energy (70 watts)” |
| kWh per cu ft (ours) | Cannot be calculated |
| Capacity | 1.7 cu ft |
| Thermostat range | Not stated |
| Freezer | Not stated |
| Refrigerant | R600a |
| Size | 17.5 W x 18.5 L x 19.7 H in |
| Listed weight | 34.2 pounds |
| Warranty | 1 year |
| Seller | Amazon.com |
| Best Sellers Rank | #110 overall; #11 in Freezers |
Why We Recommend It
The certification is clear. The title says “Energy Star”, and the last bullet says: “This compact refrigerator uses R600a refrigerant and is ENERGY STAR certified, using high-efficiency compressors that create less heat and use less energy.” With the model number, BCRK17B, you can confirm it. That puts it among the five listings on the page whose efficiency claim rests on something more than a word.
The number it gives is the wrong kind. The listing says the fridge stores food “with minimal energy (70 watts)”. Watts are power: how hard the compressor pulls while it runs. Energy is power multiplied by time, and a compressor fridge cycles on and off, so 70 watts tells you nothing about kWh a year until you know how many hours a day the compressor runs. If it ran without stopping, 70 watts would add up to 1.68 kWh a day, by our arithmetic, which is a ceiling no healthy fridge should reach. The real figure will be a fraction of that, and the listing does not say which fraction.
So it cannot join the per-cubic-foot table. We do not estimate a kWh figure for a listing that gives none. What the certification does tell you is that the model met ENERGY STAR’s threshold for its size class, which sits below the federal minimum for compact refrigerators. The annual figure behind that will be on the ENERGY STAR product finder and on the yellow EnergyGuide label, and it is worth looking up before you buy; for a 1.7 cubic foot fridge, compare it with the Midea 1.6’s 207 kWh a year.
It is a basic, well-specified small fridge otherwise. There is a removable glass shelf, “a full and half-width door storage bin” for cans and “1-liter or taller bottles”, a reversible door and adjustable legs. No thermostat range, freezer section or noise figure is stated. At 17.5 by 18.5 by 19.7 inches and 34.2 pounds, it sits under a desk.
What to weigh. It is sold by Amazon.com and ranks #110 overall, second on the page, and #11 in Freezers, an odd category for a listing that never mentions a freezer. The manufacturer field says W Appliance Company, not BLACK+DECKER, which is common for licensed brand names. Of the certified fridges, it is the one shoppers are actually buying. Look up the annual kWh by model number and it becomes a fully documented choice.
Pros
- ENERGY STAR in title and bullet
- Best-selling certified fridge, #110 overall
- R600a refrigerant, stated
- Desk-sized at 19.7 in tall
- Door bin takes 1-litre bottles
- Sold by Amazon.com
Cons
- No kWh figure, only 70 watts
- Thermostat range not stated
- Freezer not stated, yet ranked in Freezers
- No noise figure
- Made by W Appliance Company under licence
- 1-year warranty
Best for: A buyer who wants the most popular certified compact fridge and will look up its kWh by model number.
5. Upstreman 3.2 Cu Ft Mini Fridge with Freezer, BR321 — Largest Certified
The largest capacity among the certified fridges, with the claim tucked into a bullet and no kWh figure.
Key Specifications
| ENERGY STAR | Stated in third bullet only |
|---|---|
| Energy use | Not stated |
| kWh per cu ft (ours) | Cannot be calculated |
| Capacity | 3.2 cu ft (fridge 2.9, freezer 0.3) |
| Thermostat range | 32–50°F, 5 levels |
| Freezer | “Not suitable for storing ice cream and ice cubes” |
| Size (W x D x H) | 18.7 x 17.4 x 33.1 in |
| Listed weight | About 43.3 pounds |
| Noise | 38 dB, stated |
| Warranty | One year |
| Seller | Upstreman Innovation Direct |
| Best Sellers Rank | #2,525 overall; #6 in Compact Refrigerators |
Why We Recommend It
The certification is there, but you have to read to the third bullet to find it. “Designed for efficiency and Energy Star certified, it helps reduce electricity consumption while delivering reliable cooling performance.” The title does not say ENERGY STAR. Neither does any other field. With the model number, BR321, you can confirm it on the ENERGY STAR product finder, and on a listing that offers no kWh figure, that check is the only way to put a number on it.
It is the largest certified fridge here, and its energy use is the missing piece. At 3.2 cubic feet, it edges the Midea 3.1 by a tenth. We do not estimate kWh for a listing that gives none, so on the listing as it stands, the per-cubic-foot comparison cannot include it.
The freezer compartment is not a freezer in the useful sense. The capacity splits into “a 0.3 cu.ft freezer compartment and 2.9 cu.ft refrigeration space”, and the temperature bullet adds, in brackets: “Not suitable for storing ice cream and ice cubes”. That is an honest line, and an important one. A small freezer box that cannot hold ice is a chiller. If you want frozen food, the Midea 3.1 or the Cucina Magica is the better match, and our mini fridge with freezer roundup covers more.
The noise figure is one of the lower ones. “Operating at only 38 dB, this quiet mini fridge runs smoothly without disturbing sleep, study, or work.” Only the Frostorm’s 30 dB claim is lower on the page, with Feelfunn and EUHOMY also at 38. The fridge has “5 adjustable temperature levels ranging from 32°F to 50°F”, two adjustable glass shelves, a crisper drawer, a reversible door, leveling feet and a defrost tool.
What to weigh. It is sold by Upstreman Innovation Direct and ranks #2,525 overall and #6 in Compact Refrigerators, the best category rank among the compact refrigerators on the page. It is 33.1 inches tall, the tallest fridge here, at about 43.3 pounds listed. Confirm the certification and the annual kWh by model number, and it may be the most efficient large fridge on the page; the listing simply does not prove it.
Pros
- ENERGY STAR stated
- Largest certified capacity, 3.2 cu ft
- 38 dB stated
- Best category rank among compact refrigerators here
- Crisper drawer and two adjustable glass shelves
- Honest about its freezer limits
Cons
- No kWh figure
- Certification only in the third bullet
- Freezer not for ice cream or ice cubes
- 33.1 in tall, the tallest here
- Sold by the brand, not Amazon.com
- 1-year warranty
Best for: A buyer who wants a large certified fridge-first unit and will look up the kWh by model number.
6. Cucina Magica 2.9 Cu Ft Mini Fridge with Freezer, Double Door — Lowest Claimed kWh
The lowest kWh figure per cubic foot on the page, from a seller claim with no certification behind it.
Key Specifications
| ENERGY STAR | Not stated |
|---|---|

Why We Recommend It
On paper, this is the most efficient fridge on the page. “Daily power consumption is only 0.5kWh, helping you save on electricity while keeping your drinks and snacks perfectly chilled.” Over a year that is about 182.5 kWh, by our arithmetic, the lowest annual figure on the page. Over 2.9 cubic feet it is about 62.9 kWh per cubic foot per year, by our arithmetic, well ahead of the Midea 3.1’s about 87.1. And it achieves that with a two-door layout and a freezer the listing sets at “≤6.8°F”.
Then read what stands behind the number: nothing but the listing. There is no ENERGY STAR claim, no reference to a test standard and no statement of the setting at which 0.5 kWh was measured. A daily figure from a seller is useful, but it is not the same as an annual figure that has to clear a certification process. A thermostat set to its coldest step, a warm room or a door opened often can all push real use well above a quoted figure. On the evidence of this listing, 0.5 kWh a day is a claim, not a verified result.
The listing makes other claims of the same kind. It says the fridge provides “23% more usable storage than standard mini fridges of the same footprint”, that the freezer tray “makes ice in just 15 minutes (30% faster than average)” and that each unit “undergoes 72 hours of rigorous testing” on “Cucina Magica’s Italian production line”. None of those comparisons names its baseline. That does not make them false; it means the page asks for trust rather than offering proof.
The design is unusual and practical. At 14.96 by 14.96 inches it has the smallest footprint on the page, standing 30.12 inches tall on “2.5″ locking casters”. The fridge section runs “between 32°F-41°F (±1°F)” on a 7-level thermostat, a narrower and colder range than most here, and the LED light is “3000K warm glow”. Noise is “under 40dB”.
What to weigh. It is sold by Kangbaien under the Cucina Magica brand and ranks #171 overall, third on the page, and #4 in Standard Refrigerators. The warranty is 1 year, with “30-day hassle-free returns”. If the 0.5 kWh figure holds, it is the most efficient fridge here per cubic foot. Ask the seller for the EnergyGuide label or the test basis before you rely on it.
Pros
- 0.5 kWh/day stated, the lowest on the page
- About 62.9 kWh per cu ft by our arithmetic
- Freezer stated at 6.8°F or below
- Smallest footprint here, 14.96 in square
- Locking casters
- Third-best rank overall
Cons
- No ENERGY STAR claim
- No test basis or setting for the kWh figure
- Several unbenchmarked percentage claims
- Fridge range only 32–41°F
- Sold by a third-party seller
- 30.12 in tall
Best for: A buyer who needs a freezer in the smallest footprint and accepts a seller kWh claim without a certification.
7. Feelfunn 1.7 Cu Ft Mini Fridge with Freezer, CRF011-16 — Best Small Claimed Figure
A small fridge with a low daily figure, no certification and a freezer the bullets never describe.
Key Specifications
| ENERGY STAR | Not stated |
|---|---|
| Energy use | 0.55 kWh/day, stated |
| Annual (ours) | About 200.8 kWh/year |
| kWh per cu ft (ours) | About 118.1 per year |
| Capacity | 1.7 cu ft |
| Thermostat range | 32–50°F, 7 settings |
| Freezer | In title; no temperature or capacity stated |
| Size (D x W x H) | 16.9 x 17.5 x 19.1 in |
| Noise | ≤38 dB, stated |
| Warranty | 1 year |
| Seller | Liyingco |
| Best Sellers Rank | #13,163 overall; #24 in Compact Refrigerators |
Why We Recommend It
Among the small fridges, this listing claims the lowest figure. “This mini refrigerator consumes just 0.55 kWh per day for efficient everyday operation.” Over a year that is about 200.8 kWh, by our arithmetic, a little below the Midea 1.6’s certified 207 kWh. Over 1.7 cubic feet it is about 118.1 kWh per cubic foot per year, by our arithmetic, the best of the three fridges under two cubic feet that give a figure.
The figure has nothing behind it but the listing. There is no ENERGY STAR claim, no test basis and no thermostat setting attached to the 0.55 kWh. The same bullet goes on to estimate a daily running cost, which we do not reprint; a cost depends on your tariff, and the kWh is the part you can compare. Treat 0.55 kWh as a seller’s claim that happens to sit close to a certified figure for a similar-sized fridge, which makes it plausible, not proven.
The freezer is in the title and nowhere else. The title says “Mini Fridge with Freezer”. The bullets describe a “32°F–50°F cooling range and 7 adjustable temperature settings” and a removable shelf, and never give a freezer temperature or capacity. If ice or frozen food is the point, ask the seller how cold the top compartment gets before you buy. The model number, CRF011-16, also ends in 16 while the listing says 1.7 cubic feet, which is worth a question too.
It is the lightest fridge here and among the quietest. “Designed for quiet spaces, this mini fridge for bedroom operates at ≤38 dB.” At 16.9 by 17.5 by 19.1 inches and 26.5 pounds listed, it is the smallest and lightest unit on the page, with a reversible door and leveling feet.
What to weigh. It is sold by Liyingco and ranks #13,163 overall and #24 in Compact Refrigerators. The warranty is 1 year. It is a plausible small, quiet, efficient fridge on the numbers it gives; the Midea 1.6 offers almost the same annual figure with a certification you can check.
Pros
- 0.55 kWh/day stated
- About 118.1 kWh per cu ft by our arithmetic, best of the small fridges
- ≤38 dB stated
- 26.5 lb, the lightest here
- 32–50°F range, 7 settings
- Desk-sized at 19.1 in
Cons
- No ENERGY STAR claim
- No test basis for the kWh figure
- Freezer named in title but not described
- Model number ends in 16; listing says 1.7 cu ft
- Sold by a third-party seller
- 1-year warranty
Best for: A buyer who wants a light, quiet desk fridge with a low claimed figure and can live without a certification.
8. Frostorm 1.6 Cu Ft Mini Fridge with Freezer, BC-50-1 — Best Seller
The best-selling fridge on the page, with a daily kWh claim, no certification and the highest kWh per cubic foot of the seven.
Key Specifications
| ENERGY STAR | Not stated |
|---|---|
| Energy use | 0.6 kWh/day average, stated |
| Annual (ours) | About 219 kWh/year |
| kWh per cu ft (ours) | About 136.9 per year |
| Capacity | 1.6 cu ft (freezer 0.2) |
| Freezer range | -14°C to -24°C (about 6.8°F to -11.2°F, our conversion) |
| Thermostat | Mechanical, 1–5; setting 3 recommended |
| Size | 19.2 W x 18.7 L x 17.1 H in |
| Noise | 30 dB, stated |
| Warranty | 1 year |
| Seller | Frostorm-Direct |
| Best Sellers Rank | #18 overall; #1 in Upright Freezers |
Why We Recommend It
This is the fridge most shoppers on this page are buying. It ranks #18 overall on Amazon and #1 in Upright Freezers, far ahead of anything else here. Its efficiency case is a bullet headed “Energy Efficient & Cost Effective – Saves You Money”, and it does give a number: “this mini fridge consumes an average of only 0.6 kWh per day”. It also gives a daily cost estimate, which we do not reprint.
Per cubic foot, it comes last of the seven. 0.6 kWh a day is about 219 kWh a year, by our arithmetic, more than the Midea 1.6’s certified 207 kWh for the same 1.6 cubic feet. Divided by capacity, that is about 136.9 kWh per cubic foot per year, by our arithmetic, the highest of the seven listings that give a figure. There is a reason: this fridge runs a true freezer section, quoted at “-14°C to -24°C”, about 6.8°F to -11.2°F by our conversion, in a very small box. Freezing costs energy, and the Midea 1.6 has only a chiller.
The figure is a claim, with one helpful detail. There is no ENERGY STAR statement and no test standard. But the listing does tie its advice to a setting: the thermostat is a “simple 1-5 mechanical thermostat (recommended setting 3 for daily use)”, and it repeats that setting 3 is best “for optimal freshness and energy efficiency”. Read the 0.6 kWh as an average at a middle setting. Turn it to 5 and expect more.
It claims the lowest noise on the page. “With an exceptionally low 30dB ultra-quiet operation, it keeps your drinks and snacks chilled without disrupting sleep, study, or work.” No other listing goes below 38 dB. The cabinet is “durable PCM steel” with “high-density foam insulation”, a metal shelf and an ice scraper. It runs on 115V/60Hz with an “ETL-certified plug”, a safety listing, not an efficiency one. The listing asks you to let it stand for about 12 hours before first use.
What to weigh. It is sold by Frostorm-Direct, and the listed weight, 40.65 pounds, is heavy for 1.6 cubic feet; at 17.1 inches tall it is the shortest fridge here. The warranty is 1 year. It is popular, quiet and has a working freezer. On the listing’s own numbers, it is not the most efficient small fridge here; the certified Midea 1.6 uses less in a year, without a freezer.
Pros
- Best rank on the page, #18 overall
- 30 dB stated, the quietest claim here
- True freezer, -14 to -24°C
- Recommended thermostat setting given
- 17.1 in tall, the shortest here
- kWh figure stated
Cons
- No ENERGY STAR claim
- About 136.9 kWh per cu ft by our arithmetic, highest of the seven
- About 219 kWh/year by our arithmetic, above the certified Midea 1.6
- 0.2 cu ft freezer is small
- Sold by the brand, not Amazon.com
- 40.65 lb listed for 1.6 cu ft
Best for: A buyer who wants a very quiet small fridge with a real freezer, and values that over the lowest energy use.
9. EUHOMY 3.2 Cu Ft Mini Fridge with Freezer, RSD-32H — Largest Claimed Figure
A large fridge with a low claimed figure, qualified by the two words that matter: “as low as”.
Key Specifications
| ENERGY STAR | Not stated |
|---|---|
| Energy use | “As low as 0.66 kWh per day” |
| Annual (ours) | About 240.9 kWh/year at that figure |
| kWh per cu ft (ours) | About 75.3 per year at that figure |
| Capacity | 3.2 cu ft (fridge 2.9, micro-freezer 0.3) |
| Fridge range | 25–44°F |
| Micro-freezer range | 23–41°F |
| Size (D x W x H) | 19.0 x 17.5 x 31.1 in (spec table 31.0 in) |
| Noise | 38 dB, stated |
| Warranty | 1 year |
| Seller | Amazon.com (scarce stock at capture) |
| Best Sellers Rank | #13,581 overall; #25 in Compact Refrigerators |
Why We Recommend It
The first bullet leads with energy, and hedges it. “Energy Conservation – Our mini fridge consumes as low as 0.66 kWh per day, it is energy saving.” “As low as” is the language of a best case. Frostorm says “an average of”; Cucina Magica and Feelfunn give a plain figure; EUHOMY gives the floor. On a page that is about evidence, that distinction matters: a floor is not what a fridge uses on a normal day.
Taken at face value, the ratio is strong. 0.66 kWh a day is about 240.9 kWh a year, by our arithmetic. Over 3.2 cubic feet that is about 75.3 kWh per cubic foot per year, by our arithmetic, second only to the Cucina Magica on the page and ahead of the certified Midea 3.1. But the Midea’s 270 kWh is a certified annual figure, and this is an uncertified best case. Compare like with like, and the honest conclusion is that the EUHOMY might be more efficient than the Midea 3.1 per cubic foot, and the listing cannot show it.
The freezer is a micro-freezer, and the listing says so. The capacity splits into “2.9 Cu.ft Refrigeration section (25℉~44℉) and 0.3 Cu.ft micro-freezer section (23℉~41℉)”. A compartment that tops out at 41°F and bottoms out at 23°F is for short-term chilling of meat, which is how the listing pitches it, not for ice cream. That also helps the energy figure, since it never has to run a true freezer.
The rest is practical. A drip tray collects condensation when defrosting. The noise is “only 38dB”. There is a “7-position temperature control knob”, with “Model 3 is recommended for daily use”, two removable glass shelves and adjustable feet. The listing gives 19.0 by 17.5 by 31.1 inches and claims the fridge “takes up only 2.2ft²”; the spec table gives 31.0 inches tall. The model field reads RSD-32H and the part number RF001-32.
What to weigh. It is sold by Amazon.com, flagged as scarce stock at capture, and ranks #13,581 overall and #25 in Compact Refrigerators, the lowest rank on the page. The warranty is 1 year. A large, quiet fridge-first unit with a promising figure, as long as you read “as low as” for what it is.
Pros
- Low claimed figure per cu ft, about 75.3 by our arithmetic
- 3.2 cu ft, joint largest here
- 38 dB stated
- Drip tray for defrosting
- Recommended thermostat setting given
- Sold by Amazon.com
Cons
- “As low as” is a best case, not an average
- No ENERGY STAR claim
- Micro-freezer only reaches 23°F
- Two different heights listed
- Scarce stock at capture
- Lowest rank on the page
Best for: A buyer who wants a large fridge-first unit with a low claimed figure, and does not need frozen storage.
10. Frigidaire EFR176 Retro Mini Refrigerator, 1.6 Cu Ft, Coral — Best Retro Style
The only listing with neither a certification nor a kWh figure, and the word “Energy Saving” in its title.
Key Specifications
| ENERGY STAR | Not stated |
|---|---|
| Energy use | Not stated; “Energy Saving” in title |
| kWh per cu ft (ours) | Cannot be calculated |
| Capacity | 1.6 cu ft |
| Thermostat range | Not stated; “Adjustable Thermostat Control” |
| Freezer | Not stated; chiller compartment and ice cube tray |
| Size | 21.0 W x 19.0 L x 21.0 H in |
| Listed weight | About 29.9 pounds |
| Noise | Not stated |
| Warranty | 1 year |
| Seller | Amazon.com |
| Best Sellers Rank | #4,464 overall; #10 in Compact Refrigerators |
Why We Recommend It
“Energy Saving” is in the title, and that is the whole case. The title runs: “Retro Mini Refrigerator-Energy Saving-Adjustable Thermostat Control-Side Mounted Bottle Opener”. Not one of the five bullets mentions energy again. There is no ENERGY STAR claim, no kWh figure, no wattage and no refrigerant. On a page where seven listings give a number and five name a certification, this is the one that gives you nothing to check.
That does not mean it uses a lot of power. It means the listing does not let you know. A 1.6 cubic foot compressor fridge could use about as much as the Midea 1.6’s 207 kWh a year, or noticeably more, and nothing here narrows it down. The yellow EnergyGuide label that compact refrigerators sold in the US carry would give an annual figure. Ask for it, or for the model’s kWh, before treating “Energy Saving” as anything more than a word.
What it does sell is style. The bullets are about looks: “Retro Charm”, an “easy-open pull handle that adds to the retro vibe” and a “built-in bottle opener on the side”. Inside there is a wire shelf, a 2-litre door basket, a “Chiller Compartment and ice cube tray” and a reversible door. The “space-saving flush back design” is the one practical layout claim.
The dimensions are unusual. The spec table gives 21.0 inches wide, 19.0 inches long and 21.0 inches tall, which makes it the widest fridge on the page for a 1.6 cubic foot box. The manufacturer field names Curtis International, not Frigidaire, a licensed-brand arrangement like BLACK+DECKER’s. The binding field says Automotive, which is a catalogue quirk, not a claim.
What to weigh. It is sold by Amazon.com and ranks #4,464 overall and #10 in Compact Refrigerators, ahead of all three fully documented Midea listings. The warranty is 1 year. If you want the look, buy it for the look. If efficiency is why you are shopping, this listing offers you no evidence, and for the same 1.6 cubic feet the Midea 1.6 offers both a certification and a figure. For other small compact fridges, see our mini fridge cooler guide.
Pros
- Distinctive retro styling
- Side-mounted bottle opener
- Chiller compartment and ice cube tray
- Flush back design
- Ranks ahead of the three Midea listings
- Sold by Amazon.com
Cons
- “Energy Saving” with no certification or kWh
- No wattage or refrigerant stated
- Thermostat range not stated
- No noise figure
- 21 in wide for 1.6 cu ft
- Made by Curtis International under licence
Best for: A buyer who wants a retro-styled small fridge and will ask for the EnergyGuide figure before relying on the efficiency claim.
Five Stars, Seven Numbers, Three Both
A mini fridge listing can back an efficiency claim in two ways. It can state an ENERGY STAR certification, which means the model has met a threshold set below the federal minimum for its size class and can be looked up by model number. Or it can state how much energy the fridge uses, in kWh. The first tells you it cleared a bar; the second tells you by how much, if the figure is honest. The table sets out which of the ten do which.
| Fridge | ENERGY STAR stated | kWh stated | Where the claim appears |
|---|---|---|---|
| Midea 3.1 | Yes | 270 kWh/year | Title and bullet |
| Midea 1.6 | Yes | 207 kWh/year | Title and bullet |
| Midea 2.7 | Yes | 255 kWh/year | Title and first bullet |
| BLACK+DECKER 1.7 | Yes | No (70 watts) | Title and bullet |
| Upstreman 3.2 | Yes | No | Third bullet only |
| Cucina Magica 2.9 | No | 0.5 kWh/day | Second bullet |
| Feelfunn 1.7 | No | 0.55 kWh/day | Fourth bullet |
| Frostorm 1.6 | No | 0.6 kWh/day average | Third bullet |
| EUHOMY 3.2 | No | As low as 0.66 kWh/day | First bullet |
| Frigidaire EFR176 | No | No | “Energy Saving” in title only |
Three give both, and they share a brand. Every Midea listing names the certification in its title and gives an annual figure in a bullet. That combination is the strongest evidence a listing can offer: a number, and an outside body that has checked a number for the same model.
Two give the label without the number. BLACK+DECKER and Upstreman both state ENERGY STAR. Neither gives a kWh figure, and BLACK+DECKER offers 70 watts instead, which is not the same thing. These are certified on the listing’s word; the annual figure is a model-number lookup away.
Four give the number without the label. Cucina Magica, Feelfunn, Frostorm and EUHOMY all print a daily figure, none says how it was measured, and none claims a certification. Their numbers are in the same range as the certified ones, which makes them plausible. Plausible is not proven.
One gives neither. The Frigidaire says “Energy Saving” in its title and nowhere else. That is the clearest example on the page of an efficiency claim the listing does not support.
kWh per Cubic Foot, From Stated Figures Only
Raw kWh favours small fridges, because a small box uses less in total even when it uses more for each cubic foot it cools. Dividing by capacity puts a 1.6 and a 3.2 on the same scale. Everything in the last two columns is our arithmetic: daily figures multiplied by 365, then each annual figure divided by the capacity the same listing states. No figure is estimated for a fridge that gives no kWh.
| Fridge | ENERGY STAR | kWh as stated | Capacity | kWh/year (ours) | kWh per cu ft per year (ours) |
|---|---|---|---|---|---|
| Cucina Magica 2.9 | Not stated | 0.5/day | 2.9 cu ft | About 182.5 | About 62.9 |
| EUHOMY 3.2 | Not stated | As low as 0.66/day | 3.2 cu ft | About 240.9 | About 75.3 |
| Midea 3.1 | Yes | 270/year | 3.1 cu ft | 270 | About 87.1 |
| Midea 2.7 | Yes | 255/year | 2.7 cu ft | 255 | About 94.4 |
| Feelfunn 1.7 | Not stated | 0.55/day | 1.7 cu ft | About 200.8 | About 118.1 |
| Midea 1.6 | Yes | 207/year | 1.6 cu ft | 207 | About 129.4 |
| Frostorm 1.6 | Not stated | 0.6/day average | 1.6 cu ft | About 219 | About 136.9 |
| BLACK+DECKER 1.7 | Yes | Not stated | 1.7 cu ft | — | — |
| Upstreman 3.2 | Yes | Not stated | 3.2 cu ft | — | — |
| Frigidaire EFR176 | Not stated | Not stated | 1.6 cu ft | — | — |
The top two are uncertified. The Cucina Magica and the EUHOMY lead on the ratio, and both rest on seller figures alone. The EUHOMY’s figure is also a best case, “as low as”. If their numbers hold, they are the most efficient fridges here per cubic foot. Nothing on the listings confirms that they do.
The best certified ratio belongs to the Midea 3.1. About 87.1 kWh per cubic foot per year, by our arithmetic, and it carries a freezer set as low as -11.2°F. The Midea 2.7 follows at about 94.4, fridge only. The Midea 1.6 trails at about 129.4, which is what small fridges do.
Size matters more than brand. All four fridges of 2.7 cubic feet or more that give a figure come in below 95; all three under two cubic feet come in above 115. A buyer who needs a small fridge should compare it with other small fridges. A buyer who could use either size should know that the larger one stores much more for a small rise in annual kWh: the Midea 3.1 uses 63 kWh a year more than the Midea 1.6 for almost twice the space.
The total range is narrow. On the stated figures, the whole page sits between about 182.5 and 270 kWh a year, by our arithmetic. A difference of a few dozen kWh a year between two compact fridges is real but modest. The bigger risk is buying a fridge whose real use is unknown, or a type of fridge that is far less efficient by design.
What “Energy Saving” Means Without a Label
Efficiency language is free. Here is every phrase on the page that claims efficiency, and what stands behind it.
- “Energy Saving” — Frigidaire, title only. Nothing behind it.
- “Energy Efficient & Cost Effective – Saves You Money” — Frostorm. Backed by 0.6 kWh a day average, a seller figure, and a running-cost estimate we do not reprint.
- “Energy Efficient, Lower Daily Use” — Feelfunn. Backed by 0.55 kWh a day, a seller figure, and another cost estimate.
- “Energy Conservation” — EUHOMY. Backed by “as low as” 0.66 kWh a day, a best case.
- “Quiet & Efficient Operation” — Cucina Magica. Backed by 0.5 kWh a day, a seller figure.
- “minimal energy (70 watts)” — BLACK+DECKER. A power draw, with a certification alongside.
- “Designed for efficiency and Energy Star certified” — Upstreman. A certification, no figure.
- “Meets government energy efficiency standards” — Midea 2.7, with 255 kWh a year. Both.
A seller’s daily figure is better than nothing, and weaker than a label. None of the four daily claims states a test method, a room temperature or a thermostat setting, though Frostorm and EUHOMY at least recommend setting 3 for daily use. Real use rises with a colder setting, a warmer room, a fridge pushed against a wall and a door opened often. A certified annual figure comes from a standard test, so it compares fairly across brands. An uncertified daily figure compares fairly only with itself.
Watts are not kWh. BLACK+DECKER’s 70 watts is how hard the compressor pulls while running. A compressor fridge cycles, so the energy over a day depends on how many hours it runs. At 70 watts for 24 hours, a fridge would use 1.68 kWh, by our arithmetic, but no fridge should run continuously, so that is a ceiling, not an estimate. The listing’s certification is the better evidence.
The design type matters as much as the label. Every fridge here is a compressor fridge, the same basic type as a kitchen refrigerator. Thermoelectric personal fridges, the small plastic boxes that cool with a solid-state module and often double as warmers, are as a rule far less efficient: they draw power continuously and struggle to get much below room temperature. If efficiency is the goal, a small compressor fridge is the starting point; our mini fridge cooler guide explains why the cooler-style boxes behave differently.
The EnergyGuide label is the tie-breaker. Compact refrigerators sold in the US carry the yellow EnergyGuide label with an estimated annual kWh. A seller who will not tell you the figure on that label is asking you to take “energy saving” on trust.
Popularity Does Not Follow the Label
Star ratings were not captured for this roundup, so the only popularity measure is Amazon’s Best Sellers Rank, as returned on 5 October 2026. Ranks move constantly, and these ten sit in four categories, so read the overall order rather than the exact numbers.
| Fridge | Overall rank | Category rank | Evidence |
|---|---|---|---|
| Frostorm 1.6 | #18 | #1 in Upright Freezers | kWh only |
| BLACK+DECKER 1.7 | #110 | #11 in Freezers | Label only |
| Cucina Magica 2.9 | #171 | #4 in Standard Refrigerators | kWh only |
| Upstreman 3.2 | #2,525 | #6 in Compact Refrigerators | Label only |
| Frigidaire EFR176 | #4,464 | #10 in Compact Refrigerators | Neither |
| Midea 2.7 | #7,000 | #13 in Compact Refrigerators | Both |
| Midea 1.6 | #9,067 | #18 in Compact Refrigerators | Both |
| Midea 3.1 | #9,826 | #20 in Compact Refrigerators | Both |
| Feelfunn 1.7 | #13,163 | #24 in Compact Refrigerators | kWh only |
| EUHOMY 3.2 | #13,581 | #25 in Compact Refrigerators | kWh only |
The top three each have half the evidence. The Frostorm has a number and no label, BLACK+DECKER a label and no number, Cucina Magica a number and no label. The fridge with neither, the Frigidaire, outsells all three Midea listings that have both. Whatever drives these sales, it is not the completeness of the efficiency case.
The fully documented fridges sit in the middle. The three Midea listings rank #7,000, #9,067 and #9,826 overall. They are not obscure, and they are sold by Amazon.com, but they are not what most shoppers on this page pick. If you are buying for efficiency, the evidence points away from the best sellers.

What the Step Up Buys
The small fridges — Midea 1.6, Feelfunn, Frostorm, BLACK+DECKER, Frigidaire. All between 1.6 and 1.7 cubic feet, all under about 21 inches tall. Where a figure is given, they use about 200 to 219 kWh a year, by our arithmetic, or 118 to 137 kWh per cubic foot. The Midea 1.6 buys a certification and the lowest certified annual figure; the Frostorm buys a true freezer and a 30 dB claim; the Feelfunn buys the lightest box; BLACK+DECKER buys the best-selling certification; the Frigidaire buys a look.
The mid-size fridge — Midea 2.7. Stepping up to 2.7 cubic feet buys about 70% more space than the Midea 1.6 for 48 kWh a year more, and brings the ratio down to about 94.4, by our arithmetic. It buys a certified, fridge-only box at worktop height.
The large fridges — Midea 3.1, Cucina Magica, Upstreman, EUHOMY. 2.9 to 3.2 cubic feet, 30 to 33 inches tall. The Midea 3.1 buys a certified figure, the best certified ratio and a true freezer; the Cucina Magica buys the lowest claimed figure, a freezer and the smallest footprint, on trust; the Upstreman buys a certification and the biggest certified box, with no figure; the EUHOMY buys a low best-case figure and a micro-freezer.
The evidence tier matters more than the size tier. Within each size, the step that changes what you know is from a listing with one piece of evidence, or none, to one with both. On this page, only Midea makes that step at every size it sells.
What to Check Before You Buy
Look for ENERGY STAR in Writing
Five listings here state it: the three Midea models, BLACK+DECKER and Upstreman. Upstreman says it only in its third bullet, so read the whole listing, not just the title. A certification means the model cleared a threshold below the federal minimum for its class. Words like “efficient” or “energy saving” without it mean nothing has been checked.
Confirm It by Model Number
The ENERGY STAR product finder lists certified models by brand and model number. The numbers here are WHD-113FSS1, WHS-65LB1 and MERM26B0ABB for Midea, BCRK17B for BLACK+DECKER and BR321 for Upstreman. We did not run those checks; a two-minute search will confirm the claim and usually give you the annual kWh as well.
Find the Annual kWh
Seven listings give a figure: three annual, four daily. Multiply a daily figure by 365 to compare it with an annual one. On this page the results run from about 182.5 to 270 kWh a year, by our arithmetic. If a listing gives no figure, ask for the number on the yellow EnergyGuide label.
Divide by Capacity
Raw kWh flatters small fridges. Divide the annual figure by the cubic feet to compare across sizes. Here the stated figures give about 62.9 to 136.9 kWh per cubic foot per year, by our arithmetic, and every fridge of 2.7 cubic feet or more that gives a figure comes in under 95.
Read the Qualifier Next to the Number
“As low as” is a best case; “an average of” is closer to normal use; a plain figure with no method is somewhere in between. EUHOMY says as low as 0.66 kWh a day; Frostorm says an average of 0.6. Prefer a certified annual figure over any of them.
Do Not Read Watts as Energy
BLACK+DECKER states 70 watts. That is power while running, not energy over a day or a year. A compressor cycles on and off, so wattage alone cannot tell you annual use. Look for kWh.
Decide Whether You Need a Freezer
A true freezer costs energy. The Midea 3.1 and the Frostorm state freezer ranges reaching -11.2°F or about that by our conversion, and the Cucina Magica states 6.8°F or below. Upstreman says its freezer is not for ice cream or ice cubes, and EUHOMY’s micro-freezer bottoms out at 23°F. If you never freeze anything, a fridge-only box such as the Midea 2.7 avoids paying for one.
Common Mistakes
- Taking “energy saving” at its word. The Frigidaire puts it in the title and gives no certification, no kWh and no wattage.
- Reading watts as annual use. BLACK+DECKER states 70 watts; a cycling compressor makes that power, not kWh, and the annual figure is not given.
- Comparing raw kWh across sizes. The Midea 1.6 uses 63 kWh a year less than the Midea 3.1, but about 42 more per cubic foot by our arithmetic.
- Treating “as low as” as normal use. EUHOMY’s 0.66 kWh a day is a best case; Frostorm at least says its 0.6 is an average.
- Assuming a best seller is the efficient one. The #18 overall Frostorm has the highest kWh per cubic foot of the seven figures here.
- Ranking a seller figure alongside a certified one without a caveat. The Cucina Magica’s 0.5 kWh a day leads the page, with no certification or method behind it.
- Stopping at the title. Upstreman’s ENERGY STAR claim appears only in its third bullet.
- Paying for a freezer you never use. Upstreman’s 0.3 cu ft freezer is not for ice cream or ice cubes; a fridge-only box avoids running one.
Who Should Buy Which
Buy the Midea 3.1 if you want proof of efficiency and a real freezer. ENERGY STAR and 270 kWh a year stated, about 87.1 kWh per cubic foot by our arithmetic, the best of the certified three, with a freezer to -11.2°F and a 2-year compressor warranty. Accept its height, weight and silence on noise.
Buy the Midea 1.6 if you need a desk-sized fridge with a certified figure. 207 kWh a year, the lowest certified annual figure here, under 42 dB, 2-year compressor warranty. Accept a narrow 28.4–35.6°F range and no freezer.
Buy the Midea 2.7 if you want a certified fridge-only unit. 255 kWh a year in the first bullet, about 94.4 per cubic foot by our arithmetic, and the best rank of the fully documented three. Accept no freezer and no noise figure.
Buy the BLACK+DECKER if you want the best-selling certified fridge. ENERGY STAR in the title, #110 overall, desk-sized. Look up the annual kWh by model number BCRK17B, because the listing gives only 70 watts.
Buy the Upstreman if you want the largest certified box and a low noise figure. 3.2 cubic feet, 38 dB, ENERGY STAR in a bullet. Accept no kWh figure and a freezer that will not hold ice cream.
Buy the Cucina Magica if footprint is tight and you need a freezer. 14.96 inches square, 0.5 kWh a day claimed and a freezer at 6.8°F or below. Accept that the figure carries no certification.
Buy the Feelfunn if you want the lightest, quiet small fridge with a low claimed figure. 0.55 kWh a day, ≤38 dB, 26.5 pounds. Ask about the freezer before you rely on it.
Buy the Frostorm if quiet and a true freezer matter more than the lowest energy use. 30 dB claimed, a freezer to -24°C and the best rank here. Accept the highest kWh per cubic foot of the seven figures.
Buy the EUHOMY if you want a large fridge-first unit with a low best-case figure. As low as 0.66 kWh a day over 3.2 cubic feet. Accept the qualifier, a micro-freezer and scarce stock at capture.
Buy the Frigidaire for the retro look, not the efficiency claim. “Energy Saving” is the only evidence on the listing. Ask for the EnergyGuide figure first.
Frequently Asked Questions
What is the best energy efficient mini fridge?
For most buyers, the Midea 3.1 Cu Ft Mini Fridge with Freezer. Its listing states ENERGY STAR certification in the title and 270 kWh a year in a bullet, one of only three listings among the ten here to give both. Divided by its 3.1 cubic feet, that is about 87.1 kWh per cubic foot per year, by our arithmetic, the best ratio of the certified fridges, and it achieves that while running a freezer set from -11.2 to 5 degrees Fahrenheit. It also carries a 2-year compressor warranty and is sold by Amazon.com. If you need something small enough for a desk, the Midea 1.6 gives the lowest certified annual figure on the page, 207 kWh a year. Two uncertified fridges, the Cucina Magica and the EUHOMY, claim better ratios, but their figures are seller claims with no certification behind them, and one is qualified as a best case.
What is the best ENERGY STAR mini fridge?
Five of the ten listings here state ENERGY STAR certification: the Midea 3.1, Midea 1.6, Midea 2.7, BLACK+DECKER 1.7 and Upstreman 3.2. Of those, only the three Midea models also print an annual kWh figure, so they are the only certified fridges you can compare on the listing alone. The Midea 3.1 has the best ratio, about 87.1 kWh per cubic foot per year by our arithmetic, and a true freezer. The Midea 2.7 is the fridge-only choice at about 94.4, and the Midea 1.6 is the smallest at 207 kWh a year. BLACK+DECKER is the best seller among the certified five, at #110 overall, but gives 70 watts rather than kWh. Upstreman is the largest certified box at 3.2 cubic feet and gives no figure. We did not check any model in the ENERGY STAR database, so confirm by model number before buying.
How many kWh does a mini fridge use per year?
On this page, the stated figures run from about 182.5 to 270 kWh a year, with the daily figures converted at 365 days by our arithmetic. The three certified annual figures are 207 kWh for the Midea 1.6, 255 kWh for the Midea 2.7 and 270 kWh for the Midea 3.1. The four uncertified daily figures are 0.5 kWh for the Cucina Magica, 0.55 for the Feelfunn, 0.6 for the Frostorm and as low as 0.66 for the EUHOMY. Bigger fridges use a little more in total but much less per cubic foot: every fridge here of 2.7 cubic feet or more that gives a figure lands under 95 kWh per cubic foot per year, while the small ones land above 115. Real use rises with a colder thermostat setting, a warm room, poor ventilation behind the fridge and frequent door opening, so treat any listed figure as a guide rather than a guarantee.
Is an ENERGY STAR mini fridge worth it?
For a fridge that runs all day, every day, a certification is the most reliable efficiency evidence a listing can give. It means the model met ENERGY STAR’s threshold for its size class, which is set below the federal minimum, and it means you can look the model up and see its annual kWh. On this page, the certified fridges with figures sit between 207 and 270 kWh a year. Some uncertified fridges claim similar or lower figures, and they may be accurate, but nothing outside the listing has checked them. The practical answer is to treat the certification as the floor of your evidence: buy a certified model with a stated figure where you can, and if you choose an uncertified one, ask the seller for the EnergyGuide label before relying on its number. We print no running costs, because tariffs vary; compare kWh instead.
Are mini fridges with freezers less energy efficient?
Keeping a compartment below freezing takes more energy than chilling a fridge, so a true freezer adds to annual use. But the figures on this page show it does not have to make a fridge inefficient. The Midea 3.1 runs a freezer set as cold as -11.2 degrees Fahrenheit and still has the best certified ratio here, about 87.1 kWh per cubic foot per year by our arithmetic. Small fridges with freezers are harder: the Frostorm, with a 0.2 cubic foot freezer in a 1.6 cubic foot box, has the highest ratio of the seven listings that give a figure, about 136.9. Also check what kind of freezer you are getting. Upstreman says its freezer is not suitable for ice cream or ice cubes, and EUHOMY’s micro-freezer runs from 23 to 41 degrees. If you never freeze food, a fridge-only box like the Midea 2.7 avoids the extra load.
Are thermoelectric mini fridges energy efficient?
As a rule, no. Thermoelectric personal fridges cool with a solid-state module rather than a compressor, and they tend to run continuously, using a lot of energy for the small amount of cooling they deliver. Many can only get a set number of degrees below room temperature, so in a warm room they struggle to keep food properly cold at all. That is general context, not a measurement of any product, and none of the ten fridges here is thermoelectric; every one is a compressor model, the same basic type as a kitchen refrigerator. If energy use is your priority, start with a small compressor fridge and look for an ENERGY STAR claim and a kWh figure. If you want a cooler-style box for skincare or drinks on a desk, accept that it will usually use more energy for its size than anything on this page.
Does a lower thermostat setting use more energy?
Yes. The colder you set a fridge, the longer its compressor has to run to hold that temperature against the warmth of the room, and the more energy it uses. Two listings here recognise this. Frostorm recommends setting 3 on its 1 to 5 thermostat for daily use and says that setting gives optimal freshness and energy efficiency. EUHOMY also recommends setting 3 on its 7-position knob. The Midea 1.6 is a special case: its thermostat range runs from 28.4 to 35.6 degrees Fahrenheit, colder than most, so its warmest setting is still quite cold. For a fridge section, a setting that keeps food around the high 30s is usually enough. Placement matters too: leave space behind and around the fridge so it can shed heat, keep it out of direct sun and away from heaters, and let the unit stand before first use when the listing asks.
How do I check if a mini fridge is really ENERGY STAR certified?
Use the ENERGY STAR product finder, which lists certified models by brand and model number, and search for the exact model on the listing. The numbers for the five fridges here that claim certification are WHD-113FSS1, WHS-65LB1 and MERM26B0ABB for Midea, BCRK17B for BLACK+DECKER and BR321 for Upstreman. We did not run those checks for this guide, so treat the claims as the listings state them until you do. A database entry usually gives the annual kWh as well, which is useful for the two certified listings, BLACK+DECKER and Upstreman, that give no kWh figure. If the model is not in the database, ask the seller why. Separately, compact refrigerators sold in the US carry a yellow EnergyGuide label with an estimated annual kWh, and any seller should be able to tell you what it says.
Final Verdict
ENERGY STAR and 270 kWh a year stated, the best certified ratio by our arithmetic, and a freezer to -11.2°F.
207 kWh a year with ENERGY STAR, the lowest certified annual figure here, in a desk-sized cube.
The best-selling certified fridge, #110 overall; look up its annual kWh by model number.
Ten mini fridges claim efficiency, and the listings back it up in very different ways. Five state ENERGY STAR certification. Seven print a kWh figure. Three, all Midea, give both. One, the Frigidaire, says “Energy Saving” and gives neither, which on its own listing is an unverified claim.
The numbers that exist sit close together. From about 182.5 to 270 kWh a year, by our arithmetic, and from about 62.9 to 136.9 kWh per cubic foot. The lowest ratios belong to two uncertified fridges, one with a best-case qualifier. Among the certified fridges with figures, the Midea 3.1 stores the most per kWh, and does it with a true freezer.
Popularity points the other way. The three best-selling fridges here each have half the evidence, and the fully documented Midea listings sit around #7,000 to #9,826 overall. If efficiency is why you are buying, read past the rank.
So buy a mini fridge by the label and the number. Look for ENERGY STAR in writing, confirm it by model number, find the annual kWh, divide by capacity, and treat any efficiency word without those as a claim still waiting for evidence.
If you buy one fridge from this page, make it the Midea 3.1 Cu Ft Mini Fridge with Freezer: ENERGY STAR and 270 kWh a year stated, about 87.1 kWh per cubic foot by our arithmetic, a freezer to -11.2°F, and sold by Amazon.com. If it must fit under a desk, the Midea 1.6 gives the lowest certified annual figure here, 207 kWh a year.
