Champion 75531i 3100w Inverter Generator

My 2 cents, we live at 5300 ft in elevation, give or take a couple hundred feet. I own both the yami 2400 and the champion 3500/4000 open frame gen sets. The Yamaha 2400 has a series of elevation jets from sea level to high elevation (available at Wise Sales) I have the series. when we go to Silverton and higher I rejet,come back home and rejet for mid elevation, It will not run the a/c at that elevation, (but you don't need it). the champion runs the a/c at higher elevations, no adjustments needed. the champion is a work horse. going on four years with it now. like Jim said you can't be using your converter to charge while your running your a/c.
