Our Verdict: WEN 4800-Watt Dual Fuel RV-Ready Inverter

A high output dual fuel RV unit with electric start, quiet at idle but average under load.

A dual fuel inverter with a TT-30R RV outlet, electric start and 4000 running watts on gas.

So, is it any good?

On gasoline it delivers 4000 running watts and 4800 starting watts, earning the 9.

On propane it drops to 3600 running and 4320 starting watts.

It fired the RV air conditioner on the first try, but the tank ran dry faster than I expected and it is not what I would call quiet under that load.

Noise

WEN rates it 62 dBA, average for a 4800W dual fuel unit.

It is quiet at idle but climbs to a normal conversation level under real load.

Louder than the small inverters, so the 7 is honest.

Fine at a campsite spacing but not a whisper next to the RV door.

What Other Quiet Generators Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The Champion 4000-Watt Dual Fuel RV Generator is our best quiet dual fuel generator. A lot of power and dual fuel flexibility for the money, but not truly quiet under load.

The Westinghouse 5000 Peak Watt Super Quiet Portable is our best high-output quiet generator. The highest output here with remote electric start, but a big heavy unit that is only quiet at idle.

The Pulsar PGD40ISCO Ultra Light Quiet 4000W is our best lightweight 4000-watt generator. A light 46 lb 4000W inverter with good power, held back by short runtime.
