Is $779 a good price for the Champion 4500W Dual-Fuel Inverter?

$779.00 at The Home Depot as of November 5, 2026 is the best new price among 5 stores listing it. Check the price history before buying to see whether it has sold lower.

Can it run an RV air conditioner?

A typical 13,500 BTU RV air conditioner draws about 2,800 to 3,000 starting watts, which fits within the 4500 starting watts and 3500 running watts on gasoline. On propane, output is lower, so check your unit's draw.

How long does it run on a tank?

The 2.3-gallon gasoline tank supports roughly 10 to 14 hours at about 25% load in Economy Mode. Runtime drops sharply under heavy loads such as an air conditioner.

Does it work with a parallel kit?

Yes. It has a parallel port, so you can pair it with a second Champion inverter and a compatible parallel kit for more power.

What comes in the box?

The generator, a 10W-30 oil bottle, a funnel and the owner's manual. Propane hose and regulator are included for dual-fuel operation; a parallel kit is sold separately.

Is it safe to use near a tent or RV?

No. Run it outdoors, away from windows, doors and vents, with exhaust pointed away from people. CO Shield shuts the engine off at unsafe carbon monoxide levels but does not replace an indoor CO alarm.

About the Champion 4500W Dual-Fuel Inverter

The Champion Power Equipment 201531 4500-Watt Portable Inverter Generator with CO Shield is ideal for camping, tailgating, powering items around the RV or providing backup for a few basics. Power up with the reliable recoil start, plus Cold Start Technology ensures a quick start in cold weather. Just add oil (included 10W-30), and operate your Dual-Fuel generator on gasoline or propane, and easily switch fuels with the EZ Start dial. Confidently connect your sensitive electronics since this inverter produces Clean Power (less than 3% THD). Designed for safety with a low oil shut-off sensor, this model has a 0.5-quart oil capacity. Champion's Inverter Technology includes smart Economy Mode, which monitors the electrical load to reduce engine speed, noise, and fuel consumption. CO Shield technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by engine exhaust when the generator is running. If CO Shield detects unsafe elevated levels of CO gas, it automatically shuts off the engine. CO Shield is not a substitute for an indoor carbon monoxide alarm or for safe operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents or other openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300.
