I bought a little 1000w All Power generator yesterday for backup power and camping.
My Furnace fan only pulls 500w so it is about right.

Ran great and tested 129v no load. Sounds like a weed eater at half throttle.
Every time after that was one or two pulls.
I tried a drop light first and it worked fine. Then my "buddy " at work plugs in a shop vac and made it work hard. The vac ran but it nor the generator were at full speed.
I later found out that shop vac is rated at 12.5 amps.
That's 1500w! so I am certain it will make the 800/1000w rating.
Haven't used the 12v plug yet but it showed 14.9v on a meter.
