Is 8,000 watts enough for a house?

It runs most essentials through a transfer switch, such as a well pump, fridge, furnace blower and lights. Central AC and electric heat usually need more.

How long does it run on propane?

About 5 hours at the rated load on a standard tank. A larger propane tank extends runtime.

Does propane reduce the power output?

Yes. Gasoline gives the full 8,000 peak watts; propane output is lower, so plan loads around the propane rating.

What outlets does it have?

Six outlets, including a 120/240V L14-30R twist-lock for a transfer switch and 5-20R household receptacles.

Can it be used indoors or in a garage?

No. It must run outdoors, away from windows and doors. CO Shield shuts it down if carbon monoxide rises, but it is not a substitute for outdoor placement.

Portable generators often dip outside storm season and during fall sales. Check the price history before buying.

Our take on the Champion 100519 8000W Dual Fuel Portable Generator

The Champion 100519 is a 8,000-watt peak portable generator that runs on gasoline or propane, built mainly for home backup. It has a 459cc Champion engine, electric and recoil start, CO Shield carbon monoxide shutdown, and six outlets including a 120/240V L14-30R twist-lock. It is a large, heavy unit at about 74 dBA, so it suits outdoor standby use rather than camping. No current price was provided, so check the latest store comparison for where it stands against its recent range.
