    We had an issue in our warehousing district when there was only 70 volts coming out of all of our plugs due to a Edison Power Line Issue, the battery backup kept our system and internet running while the other computer we had that did not have a backup was having issues and the other internet router that was not on a backup as well kept resetting.

    Worked right out of the box. Charged battery for recommended 8 hours. Then intentionally shut off circuit breaker to my old HP desktop. Lost no data as battery worked immediately without a hitch. Plenty of time to orderly shut down. Remember: only 8 standard outlets; no other ports. Of these 8, only 4 have battery back up. I am completely satisfied.
