Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu
↓ See why we picked itBest 800-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. In this lineup alone, rated output ranges from 700W on the COMFEE' Countertop Microwave Oven up to 800W on the Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu, a real difference in heating speed that a single star rating won't tell you.
We compared all 5 models below, spanning COMFEE' Countertop Microwave Oven at $69.97 up to Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu at $129.99, 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 800-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. For example, the Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu is rated at 800W while the COMFEE' Countertop Microwave Oven is rated at 700W, a gap that changes real cook and reheat times even though both are '800-watt microwaves.'
Recipe adjustment
Compare similarly sized cavities so wattage is not confounded by appliance size. In this comparison, prices run from $69.97 on the COMFEE' Countertop Microwave Oven to $129.99 on the Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu, so it's worth confirming what specifically justifies the higher price rather than assuming the pricier pick is automatically better on this point.
Cavity size
Explain recipe-time adjustments for users moving from 1000 watts to 600, 700, 800 or 900 watts. Capacity varies too: the Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu lists 0.9 (cu. ft. or quart, per the listing) versus 0.6 on the Commercial Chef 0.6 Cu. Ft. Countertop Microwave Oven, which changes what size dish or plate actually fits.
Power control
Test defrosting and low-power behavior because high maximum wattage does not determine every task. For reference, the Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu holds the highest published rating in this comparison at 4.4 from 13,043 reviews, worth weighing against picks with a thinner review history.
Electrical draw
Publish electrical input where available and distinguish microwave output watts from wall power draw. The COMFEE' Countertop Microwave Oven has the largest review base here at 28,289 reviews, which is a stronger real-world reliability signal than rating alone on a newer, less-reviewed listing.

Nostalgia Retro Countertop Microwave Oven - Large 800-Watt - 0.9 cu
About this pick
At a genuine 800 watts, this is the only pick in the lineup running hotter than the 700W standard most competitors here use - food heats measurably faster on the same setting. Twelve pre-programmed settings is also the most of any pick in this comparison, covering specific foods rather than generic power levels.
The chrome handle and retro-styled control panel are a real aesthetic choice if a vintage look fits your kitchen, and the 0.9 cu. ft. cavity is the largest here - together they're part of why it's also the most expensive pick.

Chefman Countertop Microwave Oven 0.7 Cu. Ft.
About this pick
At 700W this runs cooler than the Nostalgia Retro pick above, so expect somewhat longer heating times on the same food - the tradeoff is a smaller footprint and a lower price. Six presets keep the interface simple without the 12-option menu of the pricier pick.
The child lock built into the handle is a detail worth having if young kids are around, since it can't be triggered by an accidental bump the way a separate button lock can.
