Yes, we routinely run the coffee pot (1200 watts) or the microwave (1100 watts input power--900 watt cooking power) on one generator. To do that, I leave the refrigerator on "GAS" (not AUTO) and turn the water heater electric switch on the water heater to OFF. We've had no problems with either of our single generators powering the microwave. I might add that we alternate our generators if we're only taking one. That way we "sort of" keep the operating hours equal.

As for the previous comments about the Champion 2000 not supporting enough power to operate the microwave, I've never had that problem with either of mine. If I did, I'd search the trailer to make sure there are no "hidden power users" and if I couldn't find any, I'd contact Champion about a generator problem.
