Be very wary of the mains output of those gmc and similar 850 watt generators. I have one and on a field day last year it destroyed a HP laptop power supply.
The multimeter showed 265 volts, but who knows what spikes and crap were also present.
Voltage regulation is very poor, drifts randomly and also according to changing load, with major surges.
The worst overvoltage is when the fuel runs out and the generator runs fast as the mix goes lean just before it stops.
All they are good for (and probably designed for) is to run power tools.
Just use it as a battery charger and for lighting.
