Home Power Facts Portable generators compared
We track 12 portable generators, from 1,800 W to 10,500 W running. 5 have a 240 V outlet (needed for well pumps and other 240 V loads) and 10 have automatic carbon-monoxide shut-off. Unlike a power station, a generator runs as long as it has fuel, but it must stay outdoors, away from the house.
Deciding between the two? See power station vs generator.

Runtime and load are the manufacturer's own figures. Gallons a day = tank ÷ runtime × 24 at that load. Fuel cost per kWh = gallons ÷ (runtime × running watts × load) × $4.33/gal, the EIA US average for regular gasoline.

These figures apply at the stated load only; manufacturers don't publish fuel use at other loads, so we don't estimate it.
