A cheap microwave should reheat coffee without cold spots, pop a bag of popcorn without burning half of it, and last longer than the first time you need to mute the beep. The budget countertop market is flooded with 700-watt boxes that look identical, but the differences in interior build quality, child lock logic, and real-world evenness separate a buy-it-once appliance from a six-month regret.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I study specification sheets, cross-reference owner complaints across hundreds of verified reviews, and track failure patterns like chipping interior paint and flimsy door clips to find the units that actually deliver consistent heating for the price.
Whether you need a dorm-friendly compact or a slightly larger unit for a small kitchen, this guide breaks down the top contenders to help you find the best cheap microwave that balances power, features, and durability.
How To Choose The Best Cheap Microwave
Picking a budget microwave means weighing trade-offs between power, capacity, control logic, and physical build quality. Here are the four specs that define whether a low-cost unit will serve you well or end up as countertop clutter.
Wattage — The Real Heating Speed
Most entry-level microwaves run at 700 watts, which is fine for reheating coffee, soup, and single servings. A 900-watt unit, like the TOSHIBA ML-EM09PA, heats food noticeably faster and delivers more even results for frozen dinners and larger portions. If you only need quick reheats, 700W is adequate. If you cook or defrost regularly, the step up to 900W is worth the small price premium.
Interior Material — Stainless vs. Painted Steel
Painted or plastic-coated interiors chip over time, as reported on the COMFEE’ model, creating potential arcing and fire hazards. Stainless steel interiors resist corrosion and clean up easily. All the units in this guide use either stainless or glass interiors, but always confirm the inner lining spec before buying — it’s a durability red line.
Child Lock Logic — Simple Disable vs. Hidden Menus
Every modern microwave includes a child lock, but the implementation varies wildly. The COMFEE’ and TOSHIBA use a simple two-step hold to lock and unlock, while the Frigidaire EMW736BLK forces you through a power-level-and-time sequence to disable it. If you want quick daily use, pick a model with a straightforward disable process.
Door Construction — Handle vs. Push-Button Release
Several reviews on the Emerson MW7601SL describe cheap plastic door clips breaking during first use, and the Frigidaire Retro’s door only opens to about 95 degrees, limiting access if placed in a corner. A solid door latch with a mechanical handle is generally more reliable than a hidden push-button mechanism on budget units.

In‑Depth Reviews
1. TOSHIBA ML-EM09PA(SS) Small Microwave Oven
The TOSHIBA ML-EM09PA brings 900 watts of real measured output into a compact 0.9-cubic-foot footprint. That extra 200 watts over the standard 700W units means frozen dinners heat through in about two-thirds the time and moisture distribution is noticeably more even. The stainless steel interior resists chipping and is easy to wipe down after splatters.
Six auto menus cover popcorn, pizza, potato, and reheat, plus defrost by weight or time. The mute function lets you silence the end-of-cycle beep, a feature often missing at this price level. The child lock is a straightforward two-step hold, so you won’t find yourself Googling how to unlock it like with some budget models.
The only consistent critique is the noise level — several owners note it runs louder than their previous microwaves. If you’re sensitive to motor hum during operation, this is worth considering. Otherwise, it’s the most capable unit in this roundup for the money.
What works
- Faster, more even heating than 700W alternatives
- Stainless steel interior withstands wear
- Simple mute and child lock controls
What doesn’t
- Audible during operation
- Display only shows time, not power level
2. COMFEE’ EM720CPL-PM Countertop Microwave Oven
The COMFEE’ EM720CPL-PM is the go-to choice if you want a microwave that doesn’t force you to listen to beeps every time you open the door. The dedicated sound on/off button silences all tones — a rare convenience in the 700W compact segment. ECO mode cuts standby power consumption by roughly half, which matters if the microwave stays plugged in 24/7.
At 0.7 cubic feet with a 10.6-inch turntable, it handles standard dinner plates and leftovers without issue. The stainless steel inner cavity is a durability plus at this price. Presets include popcorn, potato, pizza, frozen veggies, beverage, and reheat, plus two defrost modes.
The interior paint chipping reported after 18 months of use is the main longevity concern. It’s not universal, but enough owners have flagged it that you should inspect the cavity periodically. For light-duty reheating in a dorm, office, or small apartment, this remains a solid value.
What works
- One-button mute for all beeps
- ECO mode reduces standby power
- Stainless steel interior at low price
What doesn’t
- Interior paint may chip after extended use
- 700W is slower for frozen meals
3. Farberware 0.7 Cu. Ft. Countertop Microwave Oven
The Farberware 0.7 cu ft microwave offers a balanced feature set for the sub- tier. The 700-watt output is standard for this size, but the ten power levels give you more control over delicate tasks like melting butter or softening cream cheese than the six-level units. The clear LED display and interior light make it easy to monitor progress.
Six one-touch presets (popcorn, potato, pizza, frozen, reheat, beverage) plus defrost by weight or time cover the basics well. The stainless steel cavity is easy to clean, and the child safety lock is standard. Real-world reports highlight quiet operation and even heating for leftovers.
Where it stumbles is physical footprint — some owners found it larger than expected for a 0.7-cu-ft unit, taking up more counter space than comparable models. If you have a tight kitchen, measure first. For a straightforward, no-gimmick microwave that heats reliably, it delivers.
What works
- Ten power levels for precise cooking
- Quiet operation with clear LED display
- Stainless steel interior resists stains
What doesn’t
- Larger external dimensions than expected
- Child lock may require second hand to disable
4. FRIGIDAIRE EMW788RETRO 0.7 cu. ft. Retro Microwave
The Frigidaire Retro EMW788RETRO trades pure power for character. The oversized knob and azure-argent finish turn a functional appliance into a design statement. At 700 watts and 0.7 cubic feet, the heating performance is adequate for reheating coffee, soup, and simple leftovers, but it won’t accelerate a frozen lasagna the way a 900W unit would.
The child safety lock is present, and the digital touch panel integrates a timer and express cook functions. The stainless steel interior is a welcome spec at this tier. Owners consistently praise the build quality and quiet operation, and many say it looks far more expensive than it is.
The main functional quirk is the door opening only about 95 degrees, making it tricky to place in a corner or against a wall. Large plates also struggle to fit the interior. If you value aesthetics over raw speed and don’t cook large items, this retro model adds charm without sacrificing reliability.
What works
- Striking retro aesthetic with solid build
- Quiet operation and simple knob dials
- Stainless steel interior for easy cleaning
What doesn’t
- Door only opens ~95 degrees
- 700W is slow for defrosting larger items
5. BLACK+DECKER 0.7 Cu. Ft. Countertop Compact Microwave Oven
The BLACK+DECKER 0.7 cu ft model is frequently cited by van-lifers and RV owners as the smallest reliable microwave they can fit into a tight galley. The 700-watt output is paired with a handless front design for a clean look and easy wipe-down. The LED interior lighting and silent operation (quiet beep) make it unobtrusive.
Ten power levels and six one-touch programs mirror the Farberware’s feature set, including popcorn, potato, pizza, and defrost by weight or time. The memory function saves your most-used settings, a welcome convenience at this price point. The stainless steel interior is standard.
The most common gripe is that the rubber feet lack grip, causing the unit to slide when you pull the door open. Some owners also note the glass turntable can shift off-axis during operation. These are minor annoyances, not dealbreakers, for a unit this compact and affordable.
What works
- Extremely compact — ideal for vans, RVs, dorms
- Quiet beep and stainless steel interior
- Memory function for custom settings
What doesn’t
- Rubber feet let it slide when opening
- Turntable can shift off-axis
6. Emerson MW7601SL Countertop Microwave Oven
The Emerson MW7601SL stands out with its reflective mirrored finish glass door — a design detail that disguises the appliance as a decoration piece when not in use. The 700-watt, 0.7-cubic-foot interior is standard for the category, and the ten power levels give you granular control. Six presets (popcorn, pizza, potato, frozen veggie, beverage, reheat) handle daily tasks.
The time and weight defrost functions work well, and the LED display is clear at a distance. Owners who bought it for small kitchens praise the compact footprint and quiet cooking cycle. The child lock requires holding the clear button, which is straightforward once you know it.
The build quality is the weak link. Multiple verified reviews report the plastic door clips snapping on the first use, and the interior door cover is also plastic and prone to breaking. If you need something purely functional without visual flair, you are better off with a model that has a sturdier door latch.
What works
- Mirrored glass door looks premium
- Ten power levels and six presets
- Compact footprint for small cabinets
What doesn’t
- Plastic door clips prone to breaking
- Interior cover can shatter on first use
7. FRIGIDAIRE EMW736BLK 0.7 Cu. Ft. Microwave
The Frigidaire EMW736BLK is the entry-level name-brand option for buyers who trust the badge and want the lowest possible sticker. The 700-watt, 0.7-cubic-foot spec is generic, but the digital touch panel with express cooking and timer functions adds a degree of polish. Six auto-cook settings cover popcorn, baked potato, pizza, frozen, reheat, and beverage.
The child safety lock system is overly complicated — you need to press a sequence involving the power level and time buttons to disable it. Several first-time users had to Google the unlock procedure, which is frustrating for a simple microwave. The glass turntable is included, and the interior is glass, not painted steel.
The door durability is a major concern. One verified review described the door falling off after two months, and Frigidaire’s customer support directed the owner to a third-party service center with a poor reputation. If you are buying for a dorm or a space where durability is less critical, the low entry cost is tempting, but the long-term reliability data is troubling.
What works
- Very low entry price for a known brand
- Digital panel with six auto-cook settings
- Glass interior for easy cleaning
What doesn’t
- Confusing child lock disable process
- Door assembly may fail within months
Hardware & Specs Guide
Wattage Output & Heating Speed
700 watts is the baseline for cheap microwaves. It reheats a 12-ounce mug of coffee in about 90 seconds and handles medium-sized leftovers. 900 watts (as seen on the TOSHIBA ML-EM09PA) cuts that time by roughly 25% and improves evenness because the magnetron delivers energy faster, reducing cold spots. For defrosting ground meat or heating a full frozen dinner, the higher wattage is noticeably better. Always check the real output wattage, not the input power draw, which is typically higher.
Interior Material & Turntable
Stainless steel interiors resist chipping, corrosion, and arcing far better than painted or plastic-lined cavities. Glass interiors are a common budget compromise — they clean easily but can crack under thermal stress if a hot dish is placed directly on them. Most 0.7-cu-ft models include a 10-inch glass turntable. A removable turntable makes cleaning easier, but ensures the microwave is level, or the plate may wobble during operation, as reported on the BLACK+DECKER unit.

Final Thoughts: The Verdict
For most households shopping for a cheap microwave, the best all-around pick is the TOSHIBA ML-EM09PA because its 900-watt output heats evenly and quickly, the stainless steel interior outlasts painted cavities, and the simple child lock and mute function remove daily frustration. If you prioritize silence and standby efficiency over raw speed, grab the COMFEE’ EM720CPL-PM. And for a tiny footprint in a van, dorm, or RV, nothing beats the BLACK+DECKER 0.7 cu ft.
