Most Leave the Turntable Unsized on the Best 700 Watt Microwave

Affiliate Disclosure: As an Amazon Associate, we earn from qualifying purchases. This does not affect the price you pay.

Line up ten 700 watt microwaves and the headline numbers stop helping almost at once. Every listing on this page says 700 watts and 0.7 cubic feet. Not one of them steps outside that pair. Whatever separates the best 700 watt microwave from the rest of the shelf, it is not the number in the title.

The number that tells you what fits inside is the turntable, and seven of the ten leave it out. BLACK+DECKER says “removable 10” glass turntable”. The newer COMFEE says “10-inch glass turntable”. Sharp says “10" Carousel turntable”. The Nostalgia mentions a “rotating glass carousel” with no size, and the other six do not give a turntable figure at all.

Only one listing measures the cavity. The COMFEE CMO-C20M1WH gives “Internal dimensions: 12 x 11.9 x 8 (W*D*H)”. Multiply those out and you get about 0.66 cubic feet, by our arithmetic, a close match for the 0.7 on the label. It is the only listing that lets you check whether a particular plate, bowl or container will go in and turn. For the other nine, the plate question has to be answered from the turntable, or not at all.

Only one listing separates input from output. BLACK+DECKER prints “Rated Input Power(Microwave):1050W” beside its 700 cooking watts. That is the figure that matters for a dorm power strip, an office circuit or a small kitchen already running a kettle. The other nine give the 700 and nothing about what they draw from the wall.

And one listing gives an outline its own cavity cannot fit inside. The Nostalgia’s spec fields read 11.7 by 12.01 by 7.53 inches. That box holds about 1,058 cubic inches, by our arithmetic. A 0.7 cubic foot cavity is about 1,210 cubic inches. A microwave cannot be smaller on the outside than on the inside, so at least one of those figures is wrong, and the listing does not tell you which.

So this guide sorts the ten by what each listing lets you check. We set the stated turntable and cavity against the stated exterior, count the power levels and preset programs, flag where fields conflict, and note which listings say anything about input power, clearance or mounting. We also explain, as general guidance, why food made for a stronger oven takes longer in a 700 watt one, without inventing cook times that no listing gives.

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 ranks run from #77 to #144,795, and the best-ranked of them, the Chefman, is one of the seven that does not size its turntable.

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 product here states 700 watts and 0.7 cubic feet. Turntable sizes are quoted only where a listing prints one; the Nostalgia mentions a glass carousel without a size. Exterior figures are the listings’ Width, Length and Height fields, reordered as width by depth by height and rounded to two decimals where a field ran to many places; the Farberware labels its 17.75-inch figure as length and its 12.91-inch figure as width. The Frigidaire’s bullet gives 10 inches of height and its spec table 10.5. The Nostalgia’s fields describe a box of about 1,058 cubic inches, smaller than a 0.7 cu ft cavity (about 1,210 cubic inches), by our arithmetic, so we do not treat them as an exterior. Ranks are overall Best Sellers Ranks as returned on 5 October 2026. Nine were sold by Amazon.com at capture; the Danby was sold by Homestead Decor. The Danby, Sharp and GE were flagged as scarce stock. Star ratings and review counts were not captured for any product here.

How We Chose These Ten

We researched current listings, compared manufacturer specifications and documentation, and read each listing’s claims about power, capacity, turntable, controls and size 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 microwaves.

• 700 watt countertop microwaves only — every product here states 700 watts of microwave power in its title or bullets, and every one turns out to be a 0.7 cubic foot unit. Over-the-range, built-in and convection combination ovens were not in the running.
• New units, verified buy box — each product was the buy-box offer and in stock on amazon.com on 5 October 2026. Three, the Danby, Sharp and GE, were flagged as scarce stock at capture.
• Turntable and cavity recorded exactly as printed — a turntable diameter only where the listing gives one, and interior dimensions only where the listing gives them. Where a listing is silent, the table says “Not stated” and we do not estimate a cavity from the exterior.
• Input and output kept apart — 700 watts is the cooking output on every listing. A rated input figure is recorded only where it is printed, which happened once.
• Plate fit is our arithmetic — where we say a plate of a given size would or would not fit, we are comparing a plate diameter with the stated turntable or cavity figures. That judgement is ours, not the manufacturer’s.
• Controls counted from the listing — power levels and preset programs are counted only where a listing names or numbers them. Where a count is missing, it is marked not stated, even if the unit probably has the feature.
• Conflicts reported, not resolved — where two fields on one listing disagree, we print both. Where a figure cannot describe the product, we say so and do not use it.
• Popularity from Best Sellers Rank only — ranks are quoted exactly as returned on 5 October 2026. Ranks move constantly, and the COMFEE EM720CPL-PM carries a rank in Compact Microwave Ovens as well as Countertop Microwave Ovens.

The Ten 700 Watt Microwaves in Detail

Three Turntables, One Cavity, Seven Silences

Every listing here states 700 watts and 0.7 cubic feet, so the figures that separate them are the ones that describe what fits inside. The table below sets out every turntable and cavity figure the ten listings give, against their stated exteriors. The last column is our arithmetic: what the stated figures let you conclude about a plate. Where a listing gives nothing, we conclude nothing.

Where a turntable is stated, it is 10 inches. BLACK+DECKER, Sharp and the newer COMFEE all say so. A 10-inch glass tray carries a plate up to 10 inches across without overhang. Dinner plates commonly run from about 10 to 12 inches, so anything above the smallest will sit over the edge of the glass. That does not stop a plate turning, as long as it clears the walls, but it does mean the turntable figure alone cannot tell you about an 11-inch plate.

The cavity figure can, and only one listing gives it. On the COMFEE CMO-C20M1WH, the floor is 12 inches wide and 11.9 deep. A round plate spinning on the tray needs to clear the shorter of those, so it has to be under 11.9 inches across, and in practice a little less to allow for the door and the curved corners. That is our arithmetic, not COMFEE’s claim. On the stated figures, a 10.5 or 11-inch plate looks reasonable; a 12-inch one does not.

The exteriors cannot stand in for the cavity. Nine credible outlines sit between about 17 and 18 inches wide and 12.3 to 13 inches deep. But a microwave’s control panel, side walls and door take an unknown share of that, and the one listing that gives both, the COMFEE, shows how variable the gap can be: five inches of difference across the width, about 0.6 of an inch across the depth, by our arithmetic. Estimating a cavity from someone else’s ratio would be guessing, so we have not done it.

The Nostalgia is the warning case. Its fields describe a box of about 1,058 cubic inches. Its label claims a 0.7 cubic foot cavity, about 1,210 cubic inches. The outside cannot be smaller than the inside, so the listing’s outline is wrong somewhere. If a listing’s exterior cannot be trusted, neither can any plate-fit reasoning built on it.

Why 700 Watts Takes Longer, and How to Adjust

Every unit here delivers 700 watts of cooking power. Many frozen meals and packaged foods print their heating instructions for stronger ovens, and some give a separate line for lower-wattage ones. This section is general guidance, not a claim from any listing, and we do not give cook times, because no listing here does and the right time depends on the food, the quantity, the container and the starting temperature.

The basic arithmetic. A microwave’s output is the rate at which it puts energy into the food. 700 watts is 70% of 1,000 watts, and about 64% of 1,100 watts, by our arithmetic. To deliver the same energy to the same dish, a 700 watt oven has to run longer than a stronger one. The relationship is not perfectly proportional in practice, because heat spreads through food by conduction and is lost to the air at the same time, but the direction is never in doubt: less power, more time.

Use the lower-wattage line when the package gives one. Many packages print a time for a range of wattages. If yours does, follow the line that includes 700 watts rather than adjusting the higher figure yourself. If it gives only one time, written for a stronger oven, start with that time, then check, stir or turn the food and add time in short steps until it is hot throughout. The +30 seconds key on the BLACK+DECKER, COMFEE, Sharp and Chefman listings exists for exactly this.

Stir, rotate and let it stand. Microwaves heat unevenly, and lower power gives cold spots longer to persist. Stirring halfway, turning a dish that does not fit flat on the turntable, and allowing the standing time printed on the package all help heat even out. For leftovers and anything containing meat, check that the food is steaming hot in the middle, not just at the edges.

Use the power levels, not just full power. On a 700 watt unit, full power is already modest, so it is tempting to leave every job on high. But defrosting and reheating dense food work better at a lower setting for longer, so the outside does not cook while the middle stays frozen. Seven listings here state ten power levels and the CMO-C20M1WH states eleven. The EM720CPL-PM and GE do not give a count.

Cook-by-weight programs take some of the guessing out. The Frigidaire and Danby both state cook by weight, and most of the page offers defrost by weight. Entering a weight lets the microwave choose the time for its own output, which avoids the translation problem entirely for the foods those programs cover.

If most of what you cook is written for 1,000 watts or more, a stronger oven may simply be the better fit. The alternatives table below points to the 1,000 watt and mid-size classes.

Input Watts, Output Watts and the Plug

A microwave’s headline wattage is its cooking output: the microwave energy delivered into the cavity. What it draws from the socket is higher, because converting electricity into microwaves is not perfectly efficient and the fan, light, turntable motor and electronics all need power too. Only one listing here prints both figures.

Why it matters in a dorm or office. A small microwave often ends up on a shared circuit with a mini fridge, a kettle, a coffee maker or a space heater. Knowing what each one draws lets you avoid tripping a breaker every time two run together. BLACK+DECKER’s 1050 watts, about 9.5 amps at its stated 110 volts by our arithmetic, is a usable figure. The other nine leave you to look on the rating plate on the back of the unit after it arrives. Many halls of residence and offices have their own rules about which appliances are allowed; check them before you buy.

Do not read the BLACK+DECKER figure onto the others. The COMFEE EM720CPL-PM shares the BLACK+DECKER’s outline exactly and may well draw the same, but its listing does not say so. The rest are different designs from different brands. A 700 watt output does not fix the input, which depends on the design.

Standby is the other draw. Only the COMFEE EM720CPL-PM mentions it, with an ECO mode that “Minimize 50% standby power”. The listing does not give the standby figure before or after, so it is a relative claim. A microwave that sits plugged in all day with its clock lit draws a little all the time; whether that matters depends on your electricity rules more than your bill.

Power Levels, Presets and the Shortcuts

With output and capacity identical, the controls are where the ten listings actually differ in what they let you do. Here is every count the listings give.

Ten levels is the norm, and two listings do not count theirs. Seven say ten, the CMO-C20M1WH says eleven, and the EM720CPL-PM and GE give no number. Both of those almost certainly have adjustable power, but a listing that does not count its levels is a listing you cannot compare.

Six presets is the norm, and the spread runs from three to eight. The Chefman offers three, the GE four, the Nostalgia eight, and most of the rest six. More is not automatically better: a preset is only useful if it matches something you cook, and the Nostalgia does not name its eight. For a dorm or office microwave that mostly reheats, a +30 seconds key and number-key start may matter more than the menu.

Three listings state a mute. The Chefman, the COMFEE EM720CPL-PM and the Danby. In a shared room or a quiet office, being able to silence the end-of-cycle beeps is a real point in a microwave’s favour.

Popularity Runs Against the Paperwork

Star ratings were not captured for this roundup, so the only popularity measure here is Amazon’s Best Sellers Rank, as returned on 5 October 2026. Ranks move constantly. Read the order, not the precise numbers.

The best seller states the least about its inside. The Chefman, at #77 overall, gives no turntable or cavity figure. The Nostalgia, at #632, gives an outline that cannot be right. The COMFEE CMO-C20M1WH, the only listing with a measured cavity, sits seventh at #6,685. Only the BLACK+DECKER pairs a top-five category rank with a stated turntable, which is a large part of why it is our pick.

Best Alternatives

What Each Step Up Actually Buys

The basic box — Chefman, Farberware, Frigidaire, COMFEE EM720CPL-PM. 700 watts, 0.7 cubic feet, ten power levels where counted, and three to six presets. No turntable size, no cavity, no input figure. The Chefman buys the best rank and the lowest credible height; the EM720CPL-PM buys mute and ECO mode; the Farberware buys multi-stage cooking; the Frigidaire buys cook by weight and an extra seven-tenths of an inch of width.

The sized turntable — BLACK+DECKER and Sharp. A stated 10-inch turntable, which lets you confirm that a 10-inch plate sits flat. The BLACK+DECKER adds the only input figure on the page and six named presets including dinner plate; the Sharp adds two-stage cooking and LED lighting, and leaves out its weight.

The measured cavity — COMFEE CMO-C20M1WH. A 10-inch turntable and a stated 12 by 11.9 by 8 inch interior, so you can check plates, bowls and containers before you buy. Eleven power levels. It is the only listing on the page that fully answers the plate question from the manufacturer’s own figures.

The specialists — GE, Danby, Nostalgia. The GE buys clearance guidance and a replacement warranty. The Danby buys under-cabinet mounting and an 18-month in-home warranty, at the cost of a third-party seller and the lowest rank. The Nostalgia buys retro styling and eight presets, with an outline that has to be confirmed before you trust it.

Price is not the step. On this page the extra information, a sized turntable, a measured cavity, an input figure, does not follow brand or styling. It follows which listings chose to print it.

What to Check Before You Buy

Measure Your Largest Plate

Dinner plates commonly run from about 10 to 12 inches across. Every stated turntable here is 10 inches, so a larger plate overhangs the glass, and only the COMFEE CMO-C20M1WH gives a cavity figure that tells you whether it can still turn: just under 11.9 inches, by our arithmetic. If your plates are larger than 10 inches and the listing gives no cavity, ask the seller.

Plan for the Space Around It, Not Just the Box

Credible outlines here run from about 17 to 18 inches wide and 9.53 to 10.5 inches high. GE alone states clearance: 3 inches each side and above, 1 inch behind. On its figures, that is a space about 23.3 inches wide and 13.1 inches high, by our arithmetic. Check your own unit’s manual for its requirement before you box it into an alcove.

Confirm the Height Under Cabinets

The Chefman is lowest at 9.53 inches; the Frigidaire is 10 or 10.5 inches depending on the field. Under a low wall cabinet, half an inch matters, and so does the door handle and any clearance above. Use the larger figure where a listing gives two.

Find Out What It Draws From the Wall

Only the BLACK+DECKER states a rated input, 1050 watts at 110 volts. On a shared dorm or office circuit, add up everything that might run at once. For the other nine, the rating plate on the back of the unit gives the figure; look before you plug it into a crowded power strip.

Count the Power Levels You Will Use

Seven listings state ten levels and one states eleven. Low settings matter at 700 watts for defrosting and gentle reheating. If a listing does not count its levels, as the EM720CPL-PM and GE do not, you cannot compare its control range.

Check the Presets Against What You Cook

Counts run from three on the Chefman to eight on the Nostalgia. A dinner plate preset, a reheat button or cook-by-weight is more useful than a long list of programs you will never press. Unnamed presets, as on the Nostalgia, cannot be judged from the listing.

Treat Impossible Dimensions as a Red Flag

The Nostalgia’s outline, about 1,058 cubic inches, is smaller than a 0.7 cubic foot cavity, about 1,210 cubic inches, by our arithmetic. When a listing’s figures cannot describe the product, ask for confirmed dimensions before you clear the space, and do not use them to judge plate fit.

Common Mistakes

• Assuming 0.7 cu ft tells you plate size. All ten say 0.7; only one gives a cavity, 12 x 11.9 x 8 inches.
• Reading the turntable as the plate limit. A 10-inch turntable carries a 10-inch plate flat; whether an 11-inch one turns depends on the cavity.
• Following a package time written for a stronger oven. 700W is 70% of 1,000W by our arithmetic; check, stir and add time in short steps.
• Measuring for the box, not the clearance. GE asks for 3 inches each side and above, turning 17.31 inches of width into about 23.3.
• Trusting an impossible outline. The Nostalgia’s listed box is about 1,058 cubic inches, smaller than its own 0.7 cu ft cavity.
• Ignoring the plug draw. The one stated input is 1050W, about 9.5 amps at 110 V; a shared dorm circuit adds up fast.
• Taking the smaller height figure. The Frigidaire is 10 inches in one field and 10.5 in another; plan for 10.5.
• Buying on rank alone. The #1 Countertop Microwave Oven here, the Chefman, states neither turntable nor cavity.

Who Should Buy Which

Buy the BLACK+DECKER EM720CB7 if you want the best-documented 700 watt microwave. A stated 10-inch turntable, the only stated input figure, 1050 watts, ten power levels and six named presets, sold by Amazon.com at #4 in its category. Accept that it gives no cavity size.

Buy the COMFEE CMO-C20M1WH if plate fit is the question. The only stated interior, 12 by 11.9 by 8 inches, a 10-inch turntable and eleven power levels. Accept a rank well behind the top sellers and an interior depth very close to its exterior depth.

Buy the Chefman if you want the best seller and a low, simple box. #1 in Countertop Microwave Ovens, 9.53 inches tall, mute and number-key starts. Accept only three presets and no turntable or cavity figure.

Buy the COMFEE EM720CPL-PM if quiet and standby matter. Mute and a 50% standby reduction claim, in the BLACK+DECKER’s exact outline. Accept that power levels, turntable and input are not stated.

Buy the Sharp if you want a sized turntable and two-stage cooking. 10-inch carousel, ten levels, express up to six minutes. Accept scarce stock and no listed weight.

Buy the GE if you want a familiar brand and honest space planning. The only clearance figures on the page and a replacement warranty. Accept four presets and no power level count.

Buy the Nostalgia if style comes first. Retro ivory, eight presets, ten levels and a top-five category rank. Get confirmed dimensions first; the listed ones cannot be right.

Buy the Farberware if you like chained settings. Ten levels with multi-stage cooking and six one-touch programs. Accept swapped-looking dimension labels and no model number.

Buy the Frigidaire if cook-by-weight is how you like to work. Ten levels and weight-based programs. Accept 18 inches of width and a height of 10 or 10.5 inches depending on the field.

Buy the Danby if it has to hang under a cabinet. A hanging kit in the box and an 18-month in-home warranty. Accept a third-party seller, scarce stock and the heaviest body here.

Frequently Asked Questions

Final Verdict

Ten 700 watt microwaves share one power figure and one capacity, and most of them stop there. All ten say 700 watts and 0.7 cubic feet. Three size their turntable, all at 10 inches. One measures its cavity. One states its input. One prints an outline that cannot hold its own interior.

Plate fit is the question the listings mostly duck. A 10-inch turntable confirms a 10-inch plate; only the COMFEE CMO-C20M1WH’s stated 12 by 11.9 inch floor lets you reason about anything larger, and on our arithmetic a plate just under 11.9 inches is the ceiling. For the other seven, measure your plates and ask.

At 700 watts, time is the trade. Food labelled for stronger ovens will need longer here. Use the package’s lower-wattage line where there is one, stir and check, add time in short steps and use the lower power levels for defrosting. If most of what you heat is written for 1,000 watts, consider moving up a class.

If you buy one microwave from this page, make it the BLACK+DECKER EM720CB7: a stated 10-inch turntable, the only stated input figure, ten power levels and six named presets, sold by Amazon.com and ranked #4 in its category. If you need to know your plates will turn before you order, the COMFEE CMO-C20M1WH is the only listing that tells you.
