I've run the generator through about 3 tanks of fuel providing power for a 24' rv. Everything but the AC, haven't tried that. The generator runs everything well. My only complaints are that the AC and USB power lock up my I-phone, the screen doesn't respond to touch when plugged into the generator either direct through USB port or using ac/usb converter cube. And the generator surges sometimes when running in normal mode without a load.
I purchased this generator 6 months ago, and used it....alot more than 90% of the people out there would, I put alot of hours on it, did the maintenance when was needed, and it lasted longer than ANY chinese generator I have ever owned. Now for the important bit, it had a major engine failure, I called up for the warranty, 1 week later (which is amazing, because I live in Canada), a new generator arrives. So forget Honda, Yamaha, or any other brand, I have not mentioned how it starts 1-2 pulls EVERY time. I am so impressed with this company I bought another larger generator. Bottom line: Pleasure to do business with, quick response, and an excellent product that doesn't cost a months wages.
Pros: 7+ Hours on less than a gallon of gas., Quiet, Starts soooo easy.
Cons: best use is 50-65% load, past that is to much.
