    This has worked great for me so far, power has gone out once and with the alarm on it, it gives you plenty of time to shut your stuff down.

    UPS works well. The UPS battery must be charged for a minimum of eight hours before use. Meanwhile, use the surge suppression only outlet for immediate use and remember to switch to the battery & surge suppression outlet later.

    I bought this for my WiFi because our house has power fluctuations, which killed it two or three times a day. No more problems.
