Best 1200-Watt Microwaves
Best 1200-Watt Microwaves compared by installation fit, heating performance, controls, and real ownership cost.
At a Glance
Best 1200-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 7 models below, spanning TOSHIBA Microwave Oven with Smart Sensor at $182.99 up to Panasonic NN-SN67KS Microwave Oven at $289.95, 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 1200-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 $182.99 on the TOSHIBA Microwave Oven with Smart Sensor to $289.95 on the Panasonic NN-SN67KS 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 Sharp SMC2266KS 2.2 cu. ft. 1200W Stainless Steel Countertop lists 2.2 (cu. ft. or quart, per the listing) versus 1.2 on the Panasonic NN-SN67KS Microwave Oven, 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 Sharp SMC2266KS 2.2 cu. ft. 1200W Stainless Steel Countertop holds the highest published rating in this comparison at 4.5 from 339 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 Microwave Oven with Smart Sensor has the largest review base here at 3,923 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 1200-Watt Microwaves
Sharp SMC2266KS 2.2 cu. ft. 1200W Stainless Steel Countertop
About this pick
At 16.5 inches, the turntable here is noticeably larger than most in this wattage class, enough to fit two dinner plates side by side without overlap. Two-stage cooking and a dedicated Melt/Soften function cover tasks a basic reheat button can't - softening butter or chocolate without turning it into a puddle.
At 2.2 cu. ft. it also has the largest cavity in this comparison, useful if a large casserole dish or stockpot needs to fit.
Best for: buyers comparing 1200-watt microwaves who want the strongest all-around balance of features and reliability
Check price on AmazonPros
- +16.5-inch turntable, large enough for two dinner plates side by side
- +Dedicated Melt/Soften function for butter, chocolate, and similar tasks
- +2.2 cu. ft. cavity, the largest in this comparison
Cons
- −Newer listing with a shorter track record than the Toshiba pick below
- −Confirm current price and included accessories on the listing before buying
LG Countertop Microwave
About this pick
Same Smart Inverter technology as LG's other NeoChef models - continuous variable power instead of on/off cycling, which shows up as more even reheating on dense foods like rice or casseroles. Seven sensor cook presets are labeled by specific food rather than generic settings.
The glass touch panel and EasyClean interior liner are both aimed at reducing wipe-down time, a small but real convenience difference from microwaves with physical buttons and ridged interior panels.
Best for: buyers comparing 1200-watt microwaves who want a close alternative worth cross-checking against the top pick
Check price on AmazonPros
- +Smart Inverter delivers continuous variable power instead of on/off cycling
- +Seven sensor cook presets labeled by specific food, not generic settings
- +EasyClean interior liner wipes down faster than a ridged cavity
Cons
- −Newer listing with a shorter track record than the Toshiba pick below
- −Confirm current price and included accessories on the listing before buying
GE Countertop Microwave Oven
About this pick
GE's sensor here tracks moisture rather than just steam volume, adjusting cook time as food dries out rather than following a fixed timer - useful for foods that unevenly release moisture, like a baked potato. Eight auto-cook settings and one-touch express buttons cover most daily reheating without navigating a menu.
Child-lock is a genuine safety feature worth checking if young kids are in the house - it's absent on several other picks in this lineup.
Best for: buyers comparing 1200-watt microwaves who want a middle-ground option on price relative to its feature set
Check price on AmazonPros
- +Moisture-tracking sensor adjusts cook time as food dries, not a fixed timer
- +Eight auto-cook settings plus one-touch express buttons
- +Child-lock control, not present on every pick in this comparison
Cons
- −Costs more than the least expensive pick in this comparison
- −Confirm current price and included accessories on the listing before buying
TOSHIBA Microwave Oven with Smart Sensor
About this pick
The position-memory turntable is a small mechanical detail worth knowing about - it resets to its starting position after each use, so a large dish doesn't end up rotated awkwardly against the door when you open it. At 1.6 cu. ft. it's sized for family-scale reheating rather than single servings.
It's also the least expensive pick in this comparison, without giving up multi-stage cooking or the memory function found on pricier picks here.
Best for: buyers comparing 1200-watt microwaves who want more usable chamber space for bigger dishes
Check price on AmazonPros
- +Position-memory turntable resets to its starting spot after each use
- +1.6 cu. ft. cavity sized for family-scale dishes
- +Multi-stage cooking and a memory function for repeat settings
Cons
- −Fewer sensor cook presets than the Panasonic pick below
- −Confirm current price and included accessories on the listing before buying
TOSHIBA Flatbed Microwave Oven with Inverter Technology
About this pick
The flat interior is the real differentiator here - no turntable means no rotation noise, no stalling on an oversized dish, and no plate bumping against the cavity wall. It also means multiple small dishes can heat side by side instead of needing to be centered on a rotating platform.
Inverter technology delivers the same continuous variable power as LG's Smart Inverter, so reheated food is less likely to come out with hot edges and a cold center.
Best for: buyers comparing 1200-watt microwaves who want a smaller footprint for limited counter or cabinet space
Check price on AmazonPros
- +Flat interior avoids turntable noise, stalling, and plate-centering issues
- +Multiple dishes can heat side by side instead of needing to be centered
- +Inverter technology for continuous variable power instead of on/off cycling
Cons
- −Newer listing with a shorter track record than the Toshiba pick above
- −Confirm current price and included accessories on the listing before buying
LG Countertop Microwave
About this pick
This is the larger sibling of the LG NeoChef listed earlier in this comparison - same Smart Inverter and seven sensor cook presets, but stepped up to a 2.0 cu. ft. cavity. LED interior lighting and an EZ On function for single-touch start are the added extras here.
It costs more than the smaller LG above for the extra cavity room and lighting - worth it only if the smaller 1.5 cu. ft. cavity felt tight.
Best for: buyers comparing 1200-watt microwaves who want the lowest cost in this comparison
Check price on AmazonPros
- +Same Smart Inverter and sensor cook presets as the smaller LG, in a larger 2.0 cu. ft. cavity
- +LED interior lighting, not present on the smaller LG listing
- +EZ On function starts common cook times with one touch
Cons
- −Costs more than the smaller LG NeoChef in this comparison for the same core technology
- −Confirm current price and included accessories on the listing before buying
Panasonic NN-SN67KS Microwave Oven
About this pick
Panasonic's inverter delivers what it calls a seamless power stream rather than pulsed cycling, and with 16 sensor cook settings - more than any other pick in this lineup - it's built around adjusting automatically rather than relying on manual power-level guesses. Turbo defrost is also noticeably faster than the standard weight/time defrost most competitors use.
The 1.2 cu. ft. cavity is smaller than several cheaper options here - the premium buys sensor precision and defrost speed, not extra room.
Best for: buyers comparing 1200-watt microwaves who want a fuller feature set and are willing to pay more for it

Frequently Asked Questions
What do most 1200-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 1200-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 1200-watt microwaves has the most real owner feedback?
Of the products with published rating data, TOSHIBA Microwave Oven with Smart Sensor carries the largest review base at 3,923 reviews and a 4.3 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 1200-watt microwaves?
Prices across the models we compared ran from about $182.99 to $289.95 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.
