What the numbers mean

At 3,700 running watts on its best fuel, this unit covers outage essentials — a refrigerator, lights, electronics, and a furnace fan or sump pump via extension cords — but not large 240 V appliances.
Runs on gasoline, propane — expect lower output on propane (roughly 10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the published per-fuel ratings.
