    This little unit will keep small stuff running through power flickers but wont run anything substantial for long. This is your "external hard drive size UPS" dont expect it to last hours.

    We got this after a storm. The power comes and goes because they are fixing the lines. This saved out computer and receiver. Plus our tv sound stuff. It’s amazing to have one less thing to worry about.

    Needed a battery back up system quickly. Went on line - saw it on Best Buy's site and drove over to get it. In and out in less than 10 minutes. My devices are now protected again!Ea

    Bought this to keep my router and WiFi up when electricity goes out. It works just as described with no issues. Storm came electricity went out and we still had communications on all of our devices.

    Simple battery back-up, no more than a power strip in set-up and use. Does the job on the lower power pull computers.

    The battery back up caught me off guard when I tried to disconnect computer equipment before a trip. Not sure what would happen to battery if unit left unplugged for any length of time, while it was trying to run my modem. ????

    Needed this for security camera system, and it does what its supposed to. The only thing that would be better is if the plugs were turned 90 degrees, so there would be more room for the power adapters.
