Why it scored a 85
At $715, the Champion 201050 is a 4,000-watt dual-fuel inverter built for RVs, with a TT-30R outlet, 25 hours on a propane tank, and enough output for a 13,500 BTU air conditioner. Warranty leads at 100 on 3-year coverage and lifetime tech support, with Satisfaction at 90, Reliability at 88, and Features at 82. Quality sits at 76 for the open-frame design, and Value at 82 for the price. The caveat: this listing ships from a third-party seller, so check the seller before buying; Champion-sold listings exist.

Should you buy the Champion 4000W Dual Fuel?
The Champion 4000W Dual Fuel is the RV generator for people who want to run on propane. Its 4,000 starting and 3,000 running watts on gas, or 2,700 on propane, will run a 13,500 BTU RV air conditioner, and the TT-30R outlet plugs straight into the camper. At $715 it is the cheapest inverter we rank that does this, and it carries Champion's 3-year warranty with lifetime tech support. The open-frame design keeps weight to 51.8 lb but makes it louder than the enclosed Westinghouse iGen4500.
Where it earns its score
- Warranty scores 100. Three years of coverage plus lifetime technical support is the best in the category.
- 25 hours on propane. A standard 20 lb tank runs it for a full day at moderate load, and you never deal with stale gasoline.
- Runs an RV air conditioner. Enough output for a 13,500 BTU unit, with parallel ports for a second generator if you need more.
- CO Shield. Automatic carbon-monoxide shutoff, which the older WEN and Pulsar inverters lack.
What to know first
- Louder than an enclosed inverter. 64 dBA from 23 ft versus 52 for the iGen4500. Fine in a campground, noticeable at night.
- Quality is the lowest factor at 76. The open frame and plastic panel feel less refined than the Westinghouse or Honda units.
- Propane costs output. Expect 2,700 running watts on propane against 3,000 on gas.
Our verdict
The Champion 4000W Dual Fuel scores 85, a Strong Buy. It is the pick when propane and warranty matter most. The Westinghouse iGen4500 scores 86 at $849 and is quieter with remote start; if you camp near others or run it overnight, spend the extra $134.
