I have a 3500 watt running load, 4000 watt peak load, champion generator, with remote start. I am using it on a Sunnybrook 31BWKS. during deer, and elk hunting trips, I have ran it for 5-6 hours straight. Manufacture says it is only 68db running. With the remote start I can set it up, 50 or 60 feet away. It does run my microwave, refrigerator, portable heater, tv, and dvd player all at once. I have not tried my A/C unit with it yet.
This is the second champion generator I have had, still have the first one, that a buddy uses.
I paid about $420 through Cabelas for the new generator this year.
Quite happy with both of them. Much happier with the remote start at 20 degrees in the morning.
they are pretty good units, if you can get them at a good price.
