Buy too small and the fridge kills the party; buy too big and you're hauling weight and burning fuel for nothing. Our tracked set spans 1,000–3,700 W rated — here's the sizing method.

The method
List everything you'll run at once, add the running watts, then check the biggest motor load (fridge, AC, pump) against the generator's surge rating — motors pull several times their running watts at startup. Your total must fit under rated watts; your biggest appliance's startup must fit under surge watts.
The bands
Light units around 1,000 W cover phones, laptops, lights, and a small fridge. The ~2,000 W class is the camping sweet spot — fridge plus devices with margin. 3,000 W+ units start to cover RV air conditioning and home backup duty.
The data
Sorted by rated output (W), highest first. Missing specs show as — and are excluded from that model's score with the remaining weights rescaled. Full formula on the methodology page ↗
