VDOCAD i had similar experience with my champion worked really good when new but after a couple of years it would struggle to run the same loads it did so easy.
I can say i probably had over 400 hours on it and i do feel i got my 300 bucks worth of it.And it is a good buy for the price no doubt about it.
As for wattage after buying a 3000 honda i feel that the champ might be a lil overrated.It struggled to power my air compressor i can manually pick up the rpm to get it started it did fine.My honda fires it up easily
Please keep in mind that all electric/compressor motors have a LRC (Locked Rotor Current) rating that is often 3X to 5X their running current. Think of it like the pull it takes to get your RV rolling when starting on a steep upgrade. If my memory is correct, I believe the LRC for a 13,500 BTU RV air conditioner with a pancake compressor is 56 amps (6,720 watts). With R-22 refrigerant, the compressor is starting with a static head pressure of around 140 psi. The running current for the same A/C compressor is around 17 amps with the fan (2,040 watts). The Champion, as well as a slew of other 3,000 watt class Chinese synchronous generators using a GX-200 size engine have a surge current rating of no more than 4,000 watts. It should be expected to bog down and struggle when being asked to compensate for the missing 2,700 watts of surge power.
The newer scroll compressors have a similar LRC rating but the time the surge from the generator is needed to get the compressor moving is less than 1/3 of that needed by the old style compressors.
