Sharp SMC1161KB 1.1 cu. ft. 1000W Black Countertop Microwave Oven
β See why we picked itBest 1000-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 8 models below, spanning Sharp SMC1162KS 1.1 cu. ft. 1000W Stainless Steel Countertop at $129.99 up to BLACK+DECKER Over the Range Microwave Oven at $269.02, 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 1000-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 $129.99 on the Sharp SMC1162KS 1.1 cu. ft. 1000W Stainless Steel Countertop to $269.02 on the BLACK+DECKER Over the Range 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. Capacity varies too: the BLACK+DECKER Over the Range Microwave Oven lists 1.7 (cu. ft. or quart, per the listing) versus 0.9 on the LG Countertop Microwave, which changes what size dish or plate actually fits.
Cavity size
Explain recipe-time adjustments for users moving from 1000 watts to 600, 700, 800 or 900 watts. For reference, the TOSHIBA Countertop Microwave Oven with Smart Sensor holds the highest published rating in this comparison at 4.6 from 397 reviews, worth weighing against picks with a thinner review history.
Power control
Test defrosting and low-power behavior because high maximum wattage does not determine every task. The TOSHIBA Countertop Microwave Oven has the largest review base here at 32,559 reviews, which is a stronger real-world reliability signal than rating alone on a newer, less-reviewed listing.
Electrical draw
Publish electrical input where available and distinguish microwave output watts from wall power draw.
Best 1000-Watt Microwaves
TOSHIBA Countertop Microwave Oven

About this pick
The humidity sensor here isn't just a spec-sheet checkbox - it reads steam coming off the food and adjusts both time and power automatically, so a bag of popcorn or a bowl of rice doesn't need a manual power-level guess. Six preset menus and 10 power levels cover the usual reheat, defrost, and cook range without digging through a manual, and the 12.4-inch turntable fits a dinner plate without scraping the cavity wall.
The same core unit shows up two spots down on this list at a lower price - worth comparing both listings before paying full price here, since the hardware inside is identical.
Best for: buyers comparing 1000-watt microwaves who want the strongest all-around balance of features and reliability
Check price on AmazonPros
- +Humidity sensor adjusts time and power automatically instead of requiring a manual power-level guess
- +12.4-inch turntable large enough for a full dinner plate
- +Six preset menus cover common reheat and cook tasks without manual setup
Cons
- βAn identical Toshiba unit is listed cheaper elsewhere in this comparison - check both before buying
- βConfirm current price and included accessories on the listing before buying
TOSHIBA Countertop Microwave Oven

About this pick
Functionally this is the same Toshiba unit as the Best Overall pick above - same humidity sensor, same six presets, same 1.2 cu. ft. cavity - just currently listed lower.
There's no functional reason to pay more for the other listing unless this one is out of stock; price and availability are the only real decision point between the two, since the hardware and software inside are identical.
Best for: buyers comparing 1000-watt microwaves who want a close alternative worth cross-checking against the top pick
Check price on AmazonPros
- +Same humidity-sensor cooking and preset menus as the pricier listing of this unit
- +Currently the lower-priced way to get this exact model
- +1.2 cu. ft. cavity with a 12.4-inch turntable
Cons
- βNo functional upgrade over the pricier listing of the same unit - price is the only difference
- βConfirm current price and stock before buying, since Amazon listings for the same model can shift
TOSHIBA Countertop Microwave Oven with Smart Sensor

About this pick
A third Toshiba variant in this lineup, but this one trims external depth to 14.8 inches and adds a mute mode plus a memory function that recalls your last-used settings - useful if the same two or three dishes get reheated daily and you're tired of re-entering the same time and power level. Thirteen preset menus is also the most of any pick here, versus six on the two Toshiba models above.
It's a newer listing than its Toshiba siblings, so it has less of an owner track record behind it - worth weighing against the two above if a longer history of feedback matters more to you than the extra presets and quieter operation.
Best for: buyers comparing 1000-watt microwaves who want a middle-ground option on price relative to its feature set
Check price on AmazonPros
- +Mute mode silences the beep, useful for early-morning or late-night reheats
- +Memory function recalls the last-used time and power setting
- +13 preset menus, the most of any pick in this lineup
Cons
- βNewer listing with a shorter track record than its Toshiba siblings
- βConfirm current price and included accessories on the listing before buying
GE 30" Over-the-Range Microwave

About this pick
This is the only over-the-range model in the lineup, doubling as a range hood with a 300 CFM vent and a behind-the-door charcoal filter option for kitchens without external ducting. At 1.6 cu. ft. it also has more usable capacity than every countertop model here except the BLACK+DECKER.
Over-the-range installation is a bigger commitment than a countertop swap - budget for professional install if your kitchen doesn't already have compatible mounting and venting in place.
Best for: buyers comparing 1000-watt microwaves who want the lowest cost in this comparison
Check price on AmazonPros
- +Doubles as a range hood with a 300 CFM vent
- +Charcoal filter option for kitchens without external ducting
- +1.6 cu. ft. cavity, more than every countertop model in this comparison except one
Cons
- βRequires over-the-range mounting and venting, not a simple countertop swap
- βConfirm installation requirements and included accessories on the listing before buying
LG Countertop Microwave

About this pick
LG's Smart Inverter swaps the usual on/off power cycling for continuous variable power, which in practice means less rubbery reheated meat and more even melting - a real mechanical difference from the stop-start heating most microwaves in this lineup use. Auto Cook also covers seven specific foods by name, including bacon, oatmeal, and frozen entrΓ©es, rather than generic reheat and defrost buttons.
At 0.9 cu. ft. it has the smallest cavity in this comparison - a real tradeoff if you regularly heat a full dinner plate or a large bowl.
Best for: buyers comparing 1000-watt microwaves who want a fuller feature set and are willing to pay more for it
Check price on AmazonPros
- +Smart Inverter delivers continuous variable power instead of on/off cycling
- +Auto Cook presets for seven specific foods, not just generic reheat and defrost
- +EasyClean interior wipes down without scrubbing
Cons
- βSmallest cavity in this comparison at 0.9 cu. ft.
- βConfirm current price and included accessories on the listing before buying
BLACK+DECKER Over the Range Microwave Oven

About this pick
At 1.7 cu. ft. this has the largest usable cavity in the entire lineup, plus a multi-stage cooking mode that chains two power-and-time settings into one run - handy for a defrost-then-cook sequence without restarting the microwave partway through. The 1/2/3 speed keys jump straight to one, two, or three minutes at full power for quick reheats without punching in a time.
It's also the most expensive pick here, nearly double the cheapest option in this comparison. That premium buys cavity size and installation flexibility, not extra heating power, which is the same 1000W as everything else in this lineup.
Best for: buyers comparing 1000-watt microwaves who want another option worth a look if the picks above do not fit
Check price on AmazonPros
- +Largest usable cavity in this comparison at 1.7 cu. ft.
- +Multi-stage cooking chains two power and time settings into one run
- +1/2/3 speed keys jump straight into common short cook times
Cons
- βMost expensive pick in this comparison, nearly double the cheapest option
- βConfirm installation requirements and included accessories on the listing before buying

Frequently Asked Questions
What do most 1000-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 1000-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.
Which 1000-watt microwaves has the most real owner feedback?
Of the products with published rating data, TOSHIBA Countertop Microwave Oven carries the largest review base at 32,559 reviews and a 4.4 average, the strongest real-world reliability signal in this lineup. Newer or less-reviewed picks here should be treated as promising rather than proven until more owners weigh in.
What should I expect to pay for 1000-watt microwaves?
Prices across the models we compared ran from about $129.99 to $269.02 at the time of writing. Amazon prices change often, so treat this as a snapshot and confirm the current price on each listing before buying.
