Our take on the Champion Power Equipment 100573 4000-Watt DH Series Open Frame Inverter

The Champion 100573 is an open-frame inverter generator rated 4,000 peak watts and 3,000 running watts on gasoline. It stands out for clean power under 3% THD, a CO Shield carbon monoxide auto shutoff, and a 1.54-gallon tank that runs up to 10 hours. It weighs about 90 pounds and uses recoil starting, so it is portable but not a one-hand carry. It is a mid-priced inverter; check current listings for the latest price against its recent range.

Questions and answers

Is the Champion 100573 worth it over a non-inverter generator?
Yes if you run electronics, an RV or a CPAP. The inverter gives clean power under 3% THD and runs quieter and more efficiently at low load than a conventional open-frame unit.
Can it run a 15,000 BTU RV air conditioner?
Usually not on its own. A 15,000 BTU RV AC needs roughly 3,000 to 3,500 running watts plus a surge, so pair a second unit through the parallel port or step up to a larger model.
How loud is it?
Champion rates it at 64 dBA, which is moderate for an open-frame inverter. It gets louder under heavy load, so keep it away from tents and windows.
What comes in the box?
The generator, a funnel, engine oil, a battery charging cable for the recoil-start model's setup, and the owner's manual. Check the listing for the exact included accessories.
Does it have electric start?
No. The 100573 uses recoil starting only, so you pull the cord to start it.
When is it cheapest?
Inverter generators tend to dip during fall and winter, outside storm and camping season. Watch price history around holiday sales and pre-hurricane-season stock-ups.
