If it is the Pro User model that I think it is I would not risk running anything electronic off it as the waveform is not a pure sine and you risk damaging components. They are fine for powering things like cement mixers but as per geoff+emmy above I would stick to something like a Honda eu series for anything else. A few year back I tried to run a similar generator through a large commercial UPS system and the power supply was so poor the UPS could not handle the fluctuations and refused to accept an input.
