Champion 100891 9375/7500W Dual Fuel Review
7,500 running watts of dual-fuel power with electric start, usually a couple hundred dollars under the big names.
The verdict
Champion's 100891 covers the essential-circuits mission — furnace, fridge, freezer, well pump, lights — with dual-fuel flexibility and a cold-start-friendly electric start, at a price that routinely beats every comparable unit. It gives up the 50A outlet and some peak wattage to the Westinghouse; if your transfer switch is 30A anyway, you give up nothing that matters.
Typical price: ~$849 (typical street price — current price shown on Amazon)

- +7,500W running on gas covers a typical home's essential circuits with margin
- +Dual fuel with Champion's simple fuel-selector dial
- +Electric start with included battery; reliable cold-weather starting
- +CO Shield auto-shutoff standard
- +Consistently the best price in the 7,500W class
What to know
- −No 50A outlet — L14-30R (30A) is the biggest 240V connection
- −1.2-quart oil sump needs checking during long runs
- −Louder than spec sheet suggests under heavy load
Full review
Champion has quietly become the value brand that doesn't feel like a compromise, and the 100891 is the best example. The 7,500-watt class is the practical sweet spot for home backup — enough for furnace, well pump, refrigeration, and lights simultaneously — and this unit hits it for well under $900 most of the year.
The CO Shield shutoff is standard, the fuel selector is a single dial (some dual-fuel units make switching weirdly fiddly), and Champion's support network is genuinely good — parts and warranty service are easy, which matters for a machine you'll own for a decade.
The honest limitation is the 30-amp ceiling. If you dream of a 50A hookup carrying most of your panel, spend up for the Westinghouse. For the far more common 6-to-10-circuit transfer-switch setup, the 100891 is all the generator you need.
Best for: Value-focused homeowners pairing a generator with a 30A transfer switch or interlock for essential-circuit backup.
