I have a PowerMax 1000w and it works great but I needed a bit more for microwave operation so I bought a 2000 model W which seems to work all in Order, plug in, microwave on and everything worked. The USB port is convenient for charging your phone, and the port is powered even when the inverter is off. My only complaint is that I can't find a remote panel for them, even emailed PowerMax a while ago but no response. UPDATE Googled the remote again and found a seller on ebay that sold remotes for them so I ordered 2.
