I have a PowerMax 1000 watt and it works great but I needed a bit more to get the microwave working so I bought a 2000 watt model, seems to work fine, plugged it in and turned on the microwave one and it worked like zu. 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.
