You measure the countertop. Three times. The space is exactly 19 inches wide, 14 inches deep, and you’ve got maybe 11 inches of vertical clearance before the upper cabinet starts. A standard microwave won’t fit — not even close. So you start searching for a “mini microwave oven,” hoping something exists that can handle a dinner plate without taking up half your kitchen.
They exist. But finding the right one takes more than a quick search.
Mini microwaves promise the same reheating and defrosting in a smaller shell, but you have to accept trade-offs. Interior space shrinks faster than exterior dimensions: a 0.7 cubic foot model might have a 9.6-inch turntable, which means your 10.5-inch dinner plate won’t rotate. Wattage drops from 1000W to 700W, adding a full minute to a frozen dinner. And the missing features — mute buttons, child locks, interior lights — often turn a useful appliance into a frustrating one.
The market is full of cheap options, many from brands you’ve never heard of, all claiming to be “compact” or “space-saving.” But “compact” doesn’t guarantee a usable interior. Some so-called mini microwaves are barely smaller than a full-size unit; others are genuinely tiny but can’t handle a standard plate. You want both a small footprint and a usable cavity.
We looked at dozens of mini microwaves to find the ones that actually work for small kitchens, dorm rooms, offices, and RVs. We focused on models from reputable brands with reliable build quality, real user feedback, and specs that matter: wattage, turntable size, exterior dimensions, and features that make a difference day to day.
What we’ll look at
Two microwaves get a full, deep review:
- TOSHIBA ML-EM09PA(BS) — The 0.9 cu.ft. model that seems to hit all the right notes: 900W power, a 10.6-inch turntable that fits standard dinner plates, a mute function for quiet operation, and a two-step child lock. It’s a strong all-rounder.
- Chefman RJ55-SS-7-V2 — A 0.7 cu.ft. stainless steel unit that’s genuinely tiny (17.3×12.7×10.2 inches). It has a mute button and child lock too, but the 9.6-inch turntable limits plate size. If counter space is at a premium and you can live with 700W, it’s worth a close look.
Four more are worth a mention — we’ll touch on them briefly:
- BLACK+DECKER EM9P02P9 — A 0.9 cu.ft. microwave that undercuts the Toshiba on price (around $90) while offering similar power and presets. The trade-off? A loud beep you can’t silence and a dim interior light.
- COMFEE’ EM720CPL-PMB — Another 0.7 cu.ft. option, but with a trick up its sleeve: a full mute function that kills every beep, plus an ECO mode to save standby power. Great for shared dorms or open-plan offices where noise is a problem.
- Commercial CHEF CHM660W — A throwback design with mechanical dials, no digital display, and no child lock. It’s the simplest mini microwave you can buy, and it’s cheap (around $75). Best for a garage or workshop where features don’t matter.
- TOSHIBA MM-EM07PA(BK) — The smaller brother of our top pick, at 0.7 cu.ft. with a 9.6-inch turntable. It includes Toshiba’s ChefDefrost system, which genuinely speeds up thawing. But the plate size limitation and 700W power mean it’s only for users who prioritize defrosting over everything else.
These six cover the spectrum: from the best all-rounder to the cheapest option to the quietest one. No single microwave fits everyone, so we’ll call out who each one works for — and who should skip it.
Starting with the Toshiba ML-EM09PA(BS), which strikes a good balance between size and features.
Toshiba ML-EM09PA(BS): The mini that actually fits your plate
You bring home a “compact” microwave, slide it onto your counter, open the door — and realize your dinner plate won’t fit. It scrapes the sides or doesn’t rotate at all. That’s the biggest frustration with mini microwaves, and the Toshiba avoids it.
At 0.9 cubic feet, it’s not the smallest microwave on the market. But it’s small enough — 18.7 inches wide, 13.3 deep, 10.7 tall — to slide onto a tight counter or even the top of a mini-fridge in a dorm room. The real test is the interior. The 10.6-inch removable glass turntable gives you enough room for a standard dinner plate, and it rotates freely. No scraping, no tilting, no last-minute plate transfers.
Toshiba kept the cavity proportions sensible. The interior is 12.1 inches wide and 10.9 deep, which is just generous enough for most everyday dishes. A 9×13 casserole pan? Not a chance — that depth is a hard limit. But for reheating leftovers, warming up a bowl of soup, or defrosting a single-serving frozen meal, you’re not fighting the space.

Power that doesn’t wake the house
The 900-watt output is a real advantage over the 700W units that dominate this category. Frozen dinners that say “cook 6 minutes” actually take 6 minutes, not 7 or 8. Reheating a plate of pasta is done before you finish pouring a drink. And because the microwave distributes heat reasonably well (no cold spots in the center), you don’t end up with a hot rim and a cool middle.
What really stands out is the mute function. You hold down the “Sound” button for three seconds, and every beep — door open, button press, timer done — goes silent. In a shared dorm, a small apartment with thin walls, or an open-plan office, that makes a difference. Your roommate won’t be jolted awake at 2 AM because you wanted a hot pocket.
Where it stumbles
No microwave is perfect, and the Toshiba has a few quirks worth mentioning.
The interior depth (10.9 inches) is the first limitation. It’s fine for round plates up to about 10.5 inches, but oblong dishes — say, a lasagna pan or a rectangular casserole — won’t fit without rotating manually halfway through. If you regularly reheat large rectangular containers, you’ll want a…
The two-step child lock — press “Stop” and “Start” together for three seconds — is another feature most mini microwaves this size skip. Unlock by repeating the sequence. Simple, secure, and no risk of a toddler starting the microwave alone.
Where it stumbles
The Toshiba isn’t flawless.
First, the 10.9-inch depth handles round plates up to about 10.5 inches, but oblong dishes like a lasagna pan or rectangular casserole won’t fit without manually rotating halfway through. If you regularly reheat large rectangular containers, you’ll want a bigger microwave.
There’s no eco mode or programmable clock. The LED display stays bright and always on with no dimming option. In a dark dorm room, it’s a nightlight you never asked for. Not a dealbreaker, but worth knowing if you’re sensitive to light.
The black stainless steel exterior scratches more easily than some would like. A microfiber cloth helps, but keep that in mind if you move it frequently.
The door latch works, but it doesn’t feel premium — a light plastic click, not a solid thunk. Nothing has broken in our testing, but it won’t inspire confidence if you tend to slam doors.
Who it’s for
This microwave is for anyone who needs a genuine mini that still handles the basics without compromise. It’s for the dorm resident who wants to heat leftovers without waking a roommate, the studio dweller with counters measured in inches, or the office worker who needs a quiet, child-safe breakroom microwave.
It’s not for someone who regularly cooks casseroles or uses large rectangular containers. If you absolutely need an eco mode or a dimmable display, look elsewhere.
But for the vast majority of people searching for the best mini microwave oven, the Toshiba ML-EM09PA(BS) is the one to beat. It’s not a compromise — it’s a small microwave that actually works like a real microwave.
Chefman RJ55-SS-7-V2: The true tiny contender
The Chefman RJ55-SS-7-V2 is the real micro-machine. At 0.7 cubic feet, it’s among the smallest microwaves that still looks like a proper appliance — not a toy. External dimensions are 17.3×12.7×10.2 inches, fitting on a narrow shelf, desk corner, or cramped dorm cubicle.
But size comes with trade-offs.
The biggest is the 9.6-inch turntable. A standard 10-inch dinner plate won’t fit; you can squeeze a 9-inch plate or bowl, but anything larger requires manual rotation halfway. The 700-watt output is fine for reheating coffee or defrosting small meals, but frozen dinners take a full minute longer than the Toshiba. Not a crisis, just reality.
On the plus side, Chefman includes a mute button (hold “Sound” for three seconds) and a two-step child lock — surprising for a microwave under $75. The stainless steel finish resists fingerprints better than glossy black plastic, and the 10 power levels offer fine-grained control.
The missing interior light is a genuine annoyance. You have to open the door to check your food, letting heat escape and extending reheating time. Not the end of the world, but a clear corner cut.
The Chefman is best for someone with extremely limited space who prioritizes silence and safety over speed and plate size. Perfect for a dorm cubby where the microwave sits on a shelf above your desk. If you often heat full dinner plates, skip it.
For its size, it’s solid value — as long as you know what you’re giving up.

Also Worth a Look
Beyond the Toshiba and Chefman, four other mini microwaves each solve a specific niche.
BLACK+DECKER EM9P02P9: The loud but affordable 0.9 cu.ft. option
The BLACK+DECKER EM9P02P9 offers the same 900W power and 0.9 cubic feet for around $90 — a good alternative if the Toshiba is over budget. It has presets for popcorn, potato, pizza, frozen vegetables, beverages, and dinner plate, plus a child lock. But the beep is loud and can’t be muted, the interior light is dim, and some users report the turntable rattles after a few months. Fine if you can tolerate noise; otherwise, spend the extra $20 for the Toshiba.

COMFEE’ EM720CPL-PMB: The quietest mini in the lineup
At $80 and 0.7 cubic feet, the COMFEE’ EM720CPL-PMB is nearly identical to the Chefman in size, but adds a true mute function that silences every beep and an ECO mode for standby power. The 10.6-inch turntable fits a standard dinner plate — rare for a 0.7 cu.ft. microwave. Downside: 700W heating is slow, and no interior light. Best for shared dorms or open-plan offices where noise is a concern.

Commercial CHEF CHM660W: Mechanical simplicity, no frills
This is the anti-smart microwave: no digital display, no presets, no child lock — just a mechanical dial that controls the timer in 30-second increments. The pull-handle door feels solid. At 0.6 cubic feet, it’s the smallest capacity here, though the exterior isn’t much smaller than a 0.7 cu.ft. model. At around $75, it’s a decent choice for a garage, workshop, or rental where you just need heat. But skip it if you have kids — no child lock.

TOSHIBA MM-EM07PA(BK): The defrost specialist
This 0.7 cu.ft. Toshiba focuses on defrosting: the ChefDefrost system pulses lower power to thaw meat up to 40% faster while preserving texture — and it genuinely works better than standard defrost. Sound on/off and ECO mode are included, and the footprint is the smallest here (17.1×12.2×9.5 inches). Downside: the 9.6-inch turntable limits you to 9-inch plates, and 700W means slow reheating. Great if you defrost meat frequently; otherwise, the cramped turntable becomes frustrating fast.
COMFEE’ EM720CPL-PMB — The quietest mini microwave in our selection: a full mute silences every beep, plus ECO standby saves power. But 700W heating is slow, and there’s no interior light. Best for dorms or open-plan offices where noise is the main concern.
Commercial CHEF CHM660W — Mechanical dials, no digital display, no child lock, and a pull-handle door. Pure utility for a garage or rental: $75, 0.6 cu.ft., but the 30-second timer increments are imprecise and it’s a hard no for families.
TOSHIBA MM-EM07PA(BK) — The defrost specialist already described above, with the smallest footprint and fastest thawing around. Still, the 9.6-inch turntable won’t fit a dinner plate, and 700W reheating is slow. Only if you defrost a lot.

How to Choose a Mini Microwave That Actually Works
Shopping for a mini microwave seems straightforward: find something small, plug it in, go. But the differences between models matter more at this size because there’s less room for error. A few inches of interior space, a few hundred watts of power, or the presence of a mute button can turn a useful appliance into a frustrating one.
Here’s what to consider before you buy.
Measure twice, then measure again
Don’t rely solely on cubic footage. The shape of the cavity and the turntable diameter determine what actually fits. A 0.7 cu.ft. microwave with a 10.6-inch turntable (like the COMFEE’) fits a standard 10-inch dinner plate. A 0.7 cu.ft. microwave with a 9.6-inch turntable (like the Chefman or Toshiba MM-EM07PA) can’t. Same capacity, very different usability.
So check the turntable diameter and interior width and depth. If you regularly heat up full dinner plates, look for at least a 10.5-inch turntable. If you only use bowls and mugs, a 9.6-inch turntable works fine.
Also measure your actual counter space — and check the clearance above. Most mini microwaves need at least 3 inches of space on the sides and top for ventilation. If you’re placing it on a shelf or inside a cabinet, verify the manufacturer’s clearance requirements. Some models run hotter than others.
Wattage: 700W vs 900W
700W microwaves are common in the 0.7 cu.ft. range. They’re fine for reheating coffee, defrosting small portions, and cooking single-serving frozen meals — but they take longer. A frozen dinner that says “cook 6 minutes on high” will need about 7 minutes in a 700W oven. Popcorn burns more easily because the lower power doesn’t distribute heat as evenly.
900W microwaves, found in 0.9 cu.ft. models like the Toshiba ML-EM09PA and the BLACK+DECKER EM9P02P9, cook faster and more evenly. The difference is meaningful: about 20–30 seconds per minute of cooking. Over a week of reheating, that adds up.
The catch: 900W models are physically larger — about 1.5 inches wider and deeper. If your counter space is truly tight, you may have to accept 700W. If you can spare those extra inches, the 900W upgrade is worth it.
The features you’ll actually miss
Reading spec sheets, you’ll see “6 auto menus” or “10 power levels” and assume they matter. In practice, most preset buttons are just countdown timers — they don’t adjust cooking based on moisture or weight. The popcorn preset on almost every mini microwave will burn half the bag if you aren’t monitoring it.
The features that actually make a difference day-to-day:
- Mute function. A beeping microwave in a small apartment or shared dorm is annoying. Models that let you silence all beeps (Toshiba ML-EM09PA, Chefman, COMFEE’) are dramatically more pleasant to live with.
- Child lock. This is now a safety standard on most new microwaves, but some mechanical-dial models (like the Commercial CHEF) lack it entirely. If you have young children, this is non-negotiable.
- Interior light. About half the mini microwaves skip this. Without it, you have to open the door to check doneness, letting heat escape. Small annoyance, daily frustration.
- Removable turntable. All the models here have one, but check — some budget microwaves use fixed turntables that are harder to clean.
Budget: where the compromises live
Under $70, you’re looking at microwaves like the Emerson MW7302W — they save money by cutting safety (no child lock), noise control (no mute), and build quality. They’ll heat food, but that’s about it.
Between $70 and $90, you get the Chefman, COMFEE’, and Commercial CHEF — basic features like mute and child lock, but usually at 700W with small turntables.
From $90 to $110, you’re in Toshiba and BLACK+DECKER 0.9 cu.ft. territory — 900W, larger turntables, and most of the features you actually want.
The sweet spot is around $100 for most people. Below that, you’re making meaningful sacrifices. Above that, you’re in full-size microwave territory.
The one thing nobody tells you
Mini microwaves run hotter than full-size ones because the components are packed into a smaller chassis. The exterior can get warm — sometimes hot — especially on the sides and top. If you’re placing the microwave on a wooden surface or inside a tight cabinet, check the temperature after a few uses. Some models (like the Toshiba) stay cool enough for cabinet installation; others don’t.
The right pick depends on your space
There’s no single best mini microwave — the right one depends on the inches you have and the plates you use.
If you can fit a 0.9 cu.ft. microwave (18.7 inches wide, 13.3 deep, 10.7 tall) and want the best balance of power, plate fit, and quiet operation, the Toshiba ML-EM09PA(BS) is the obvious choice. It’s the rare mini that doesn’t force you to compromise on the basics — and the mute function makes it livable in close quarters.
If your space is truly tight — a dorm cubby, a narrow shelf, a desk corner — and you can live with 700W and 9-inch plates, the Chefman RJ55-SS-7-V2 is the best value at around $75. It’s small, quiet, and safe.
For noise-sensitive environments like shared dorms or open-plan offices, the COMFEE’ EM720CPL-PMB offers true mute in a slightly larger 0.7 cu.ft. package with a plate-friendly 10.6-inch turntable.
The rest are niche picks: the BLACK+DECKER if saving $20 matters more than silence, the Commercial CHEF for mechanical simplicity in a garage, and the Toshiba MM-EM07PA if you defrost meat constantly.
Measure your space. Check the turntable size. Decide whether 700W is enough. Then pick the one that fits — literally and figuratively. A mini microwave shouldn’t feel like a compromise; it should feel like the right tool for the space you have.
Q: Will a standard dinner plate fit inside a mini microwave?
A: Not all mini microwaves can fit a standard 10-inch dinner plate. The turntable diameter is the key spec—look for at least 10.5 inches if you plan to reheat full plates. Many 0.7 cu.ft. models have 9.6-inch turntables that require you to manually rotate larger dishes halfway through.
Q: Do mini microwaves get hot on the outside? Can I install one inside a cabinet?
A: Yes, compact microwaves typically run warmer on the exterior because the components are packed tightly. Always follow the manufacturer’s clearance guidelines—usually 3 inches on all sides. Some models are rated for cabinet installation, but many are not; check the manual before enclosing the unit.
Q: Can I turn off the beeping on a mini microwave?
A: Some models include a mute function that silences all beeps, but many do not. If you’re in a dorm or shared space, prioritize a microwave with a dedicated sound on/off button. Without it, the beeps can be loud and cannot be disabled.
Q: How well do mini microwaves handle frozen dinners and popcorn?
A: Lower-wattage 700W ovens cook slower, so follow package directions for 700W or add extra time. Popcorn presets often burn the bag because they are simple countdown timers rather than sensor-based. It’s safer to use manual power and time settings for more even results.
Q: How much counter space do I need for a mini microwave?
A: A typical 0.7 cu.ft. microwave measures about 17x13x10 inches. You need at least 3 inches of clearance on top and sides for ventilation. Measure both the exterior dimensions and the available space, including overhead clearance if placing it under a cabinet.
