- 4,000W rated, 4,800W surge
- TT-30R and four 120V outlets
- CO Watchdog shutdown
Our take
The powerhouse for a 30A trailer with an air conditioner.
Why it made the shortlist
The WEN 56477i delivers 4,000 rated and 4,800 surge watts from a 224cc engine, with four 120V outlets, a TT-30R RV receptacle, a 12V DC outlet and two USB ports. A CO Watchdog shutdown, fuel shut-off, onboard wheels, a telescoping handle and a three-year warranty are all listed.
It has the most rated watts of the six and clean inverter power for electronics. It out-produces the Generac 3,300 and the WEN 3600 by 1,500 and 1,100 running watts.
It suits travel trailer owners who want to run an air conditioner and a few appliances. The wheels and handle make moving it at a campground easier.
What works
- Most rated watts in the group
- TT-30R RV receptacle
- CO shutdown sensor
- Three-year warranty
Watch out for
- Weight is not stated on the listing
- The catch
- Weight is not stated, so plan on using the wheels and handle.
