It's one and the same from Guy... Only thing, for some reason we found that any motor, like a pump motor, which draws 3 amps or so, runs with a louder pitch while air pumps run at the normal pitch (sound)...
I thought it might be that the inverter was putting out too much voltage, however, was not the case, out put was normal 118-120v...
