    Not meaning to hijack thread, but this is hard for me to wrap my head around, never having seen or heard one of the champions. Can anyone quantify this? Is it "drive you and your neighbors crazy" louder? Hear it all over the campground louder? Fine for disbursed camping louder? Or not really very noticeably louder than red or blue ones?
  • At normal altitudes it would be more than enough for what you ask. It is the same size as the Honda and Yamaha 2800w inverter generators but is a bit louder.
  • 3500 watts continuous give you about 28.5 Amps. Usually enough to run your camper at near normal for a 30 Amp service.

    There are many opinions on how low the voltage can get before damage to AC motor will occur. What happens is as the voltage drops, the current (Amps) draw increases causing excess heat which will cause the motor to burn out. I've always use 105 volts as my cutoff point. I wouldn't run the AC very long at low voltage.

    Invest in a good meter so you know what is in the camper. Even at campgrounds you can see low voltage situations often.
  • Yes, by the numbers. No in practice. Here's what happens. Gen starts up putting out 127v. After running for a while, the volt output decreases 5-7v. AC goes on and the available volts goes from 120/122v down to near 110v the minimum to keep the AC going w/o damage to the compressor. You have no practical voltage left for anything else on the circuit. Minimum gen watts for 1 AC, lighting, TV, computer, fridge should be 5500 watts. As far as the brand, buying without listening to the generator's noise, is a terrible idea.
