No Kidding - a generator. But it does the job and you don't need 2 in parallel to get 30 amps or run your AC. It may produce noise, but all of them do, it's a question of how much.
The point I was making without getting too technical, it is a single phase generator! NOT the standard multi-phase that only lets you use half of the output it creates unless you are using 240Vac. That would mean you would need an 8K multiphase to do the job of the 4K single phase. My point is that the 100222 does the job of a LOUDER, HEAVIER, more EXPENSIVE 8K.
I spoke to a person the other day that was passing through with his TT and his Honda 2000 gets too hot (has a metal box around it to not get burnt!) and it will not run his air conditioning - and he only has the 13500 BTU ac.
Regarding Sound, it is 68 dBa at 23 ft. I will try to be more than 25 feet away, ...
If you want an invertor generator, Don't purchase a 100222, but if you want the real thing, consider a 100222 that's all. BTW, Champion makes an IG version that was in the link I provided.
