James Kirker

Very quick delivery and seems to work as expected. Easy to start and relatively quiet.

Bryan Strobl
Refurbed but great

This thing started on second pull and seems to be in perfect condition. I would recommend! So many generators in this size have no gas cutoff but this one does.

Mitchell Morse
Quiet and will barely run a 13,500 BTU AC unit on RV

Overall I like this generator. But unless your RV has a AC pre-start capacitor so it doesn’t suddenly place the lid directly on this one; you will need to start your fan first, let it run a minute then turn on the AC pump. Placing both on at once overloads this guy.
The biggest reason I purchased this one was for noise output, make sure to run a good synthetic as well, it only takes .6 to .7 quarts of oil which is not a lot.

Champion 100158 2800W/3100W Portable Inverter Generator
