    I bought this Cyberpower unit so I could power my cable modem and my wireless telephone system during a power failure. The main reason I wanted this unit is so I could monitor how fast I was using up my reserve power. The unit would not communicate with my laptop so I called Cyberpower customer support. They told me it was not designed to be used with laptops. I returned it to the store for a full refund.
