Best 900-Watt Microwaves
Best 900-Watt Microwaves compared by installation fit, heating performance, controls, and real ownership cost.
At a Glance
Best 900-Watt Microwaves can look similar on a spec sheet but differ in ways that matter once one is actually installed and used day to day: actual heating speed, recipe adjustment, and cavity size are the details most listings gloss over in favor of headline wattage and capacity numbers.
We compared all 5 models below, spanning Chefman Countertop Microwave Oven 0.9 Cu. Ft. at $79.88 up to TOSHIBA Microwave Oven at $117.99, with a focus on measuring real time to heat a fixed volume of water or food to a target temperature, and cross-checked power control and electrical draw against the current listing data rather than repeating manufacturer marketing claims.
5 Criteria to Look For Before Buying a 900-Watt Microwave
Key buying criteria so you get the right fit the first time.
Actual heating speed
Measure real time to heat a fixed volume of water or food to a target temperature. In this comparison, prices run from $79.88 on the Chefman Countertop Microwave Oven 0.9 Cu. Ft. to $117.99 on the TOSHIBA Microwave Oven, so it's worth confirming what specifically justifies the higher price rather than assuming the pricier pick is automatically better on this point.
Recipe adjustment
Compare similarly sized cavities so wattage is not confounded by appliance size. For reference, the TOSHIBA Microwave Oven holds the highest published rating in this comparison at 4.5 from 1,422 reviews, worth weighing against picks with a thinner review history.
Cavity size
Explain recipe-time adjustments for users moving from 1000 watts to 600, 700, 800 or 900 watts. The BLACK+DECKER Countertop Microwave Oven has the largest review base here at 12,300 reviews, which is a stronger real-world reliability signal than rating alone on a newer, less-reviewed listing.
Power control
Test defrosting and low-power behavior because high maximum wattage does not determine every task.
Electrical draw
Publish electrical input where available and distinguish microwave output watts from wall power draw.
Best 900-Watt Microwaves
Chefman Countertop Microwave Oven 0.9 Cu. Ft.
About this pick
The memory function lets you save a frequently used time-and-power combo for one-touch recall, useful if you reheat the same coffee mug or plate size daily and don't want to re-enter settings each time. Six presets cover the usual popcorn, pizza, and leftover categories.
At $79.88 it's the least expensive pick in this comparison, without giving up the memory function found on pricier competitors.

BLACK+DECKER Countertop Microwave Oven
About this pick
Six presets are labeled by specific food rather than generic power levels, and the dinner-plate setting in particular is a detail not every competitor includes. The 10.6-inch turntable is fully removable for easier cleaning, and interior lighting lets you check on food without opening the door and losing heat.
Push-button door release is simpler to operate one-handed than a pull-handle design if your other hand is holding a plate.
Best for: buyers comparing 900-watt microwaves who want a close alternative worth cross-checking against the top pick
Check price on AmazonPros
- +Six food-specific presets, including a dedicated dinner plate setting

TOSHIBA Microwave Oven
About this pick
Eleven power levels is one more increment than the 10-level standard most competitors in this comparison use, giving slightly finer control between low and high settings. Two-step child lock requires a specific sequence rather than a single button, harder for a young child to trigger by accident.
At 1400W input power, it also draws less from the wall circuit than some competitors at a similar output, worth checking if you're on a shared kitchen circuit.
Best for: buyers comparing 900-watt microwaves who want a middle-ground option on price relative to its feature set
Check price on AmazonPros
- +11 power levels, one more increment than the 10-level standard
- +Two-step child lock requires a specific sequence, not a single button
- +1400W input draw, worth checking against your kitchen circuit
Cons
- −Fewer presets than the BLACK+DECKER picks in this comparison
- −Confirm current price and included accessories on the listing before buying
TOSHIBA Microwave Oven
About this pick
Functionally the same Toshiba unit as the pick above - same two-step child lock, same 11 power levels, same 10.6-inch turntable - just currently listed at a higher price.
There's no functional reason to pay more for this listing unless the cheaper one is out of stock; compare both before buying.
Best for: buyers comparing 900-watt microwaves who want more usable chamber space for bigger dishes
Check price on AmazonPros
- +Same two-step child lock and 11 power levels as the lower-priced Toshiba listing
- +Same 10.6-inch turntable and 6 preset menus
- +Identical hardware to a cheaper listing in this comparison
Cons
- −No functional upgrade over the cheaper Toshiba listing in this comparison

BLACK+DECKER Countertop Microwave Oven 0.9 Cu Ft
About this pick
This is a step up from the other BLACK+DECKER in this comparison, adding a memory function for recalling a favorite setting and a one-touch start for the most common cook time. Six preset menus and 10 power levels otherwise match its sibling.
The memory function is the real differentiator here - worth the extra cost only if you'd actually use a saved custom setting regularly rather than relying on the presets.
Best for: buyers comparing 900-watt microwaves who want a smaller footprint for limited counter or cabinet space

- +Memory function recalls a favorite time-and-power setting

Frequently Asked Questions
What do most 900-watt microwaves listings leave out?
Publish electrical input where available and distinguish microwave output watts from wall power draw. Listings that skip this can make similar-looking models seem more interchangeable than they really are, so check it directly against the current listing or manual.
Is it safe to keep using a 900-watt microwave with a damaged door or seal?
No. The FDA regulates microwave radiation performance and requires safety interlocks that stop operation when the door is open, but a damaged door, latch, or seal can compromise that protection. Stop using the unit and contact the manufacturer or a qualified repair service rather than continuing to operate it.

Of the products with published rating data, BLACK+DECKER Countertop Microwave Oven carries the largest review base at 12,300 reviews and a 4.4 average, the strongest real-world reliability signal in this lineup.
