    Bought this battery back up system because the old one that I had for more than 10 years just died on me. I chose this one because this has 8 outlets compared to the old one I had with only 6 outlets!!

    This is my second charger. The other model finally stopped charging, but I did not realize that you could just change the battery (do not know what happened to my old instructions) so I bought a second unit and found out about the battery with the new instructions. So if you purchase one of these realize that you can change the battery (however, I do not know what this entails or how much a new battery costs).

    The only problem I have with this is only one side of the plugs are hot when the power foes out. Make sure you plug the Important stuff into the right side.

    I bought a cheap UPS for a backup for my internet. Plug it in and it goes. Notifies you if the power goes out, but it keeps on running. Don't expect this to run a whole computer, but for something small like internet it is a good investment. I had it plugged into my gaming desktop, and I got maybe 1 minute out of it on battery alone while not even gaming.

    Bought this to provide battery back-up source of power for my power recliner. It works, but.... Pictures are false as there is no USB Type-A port on this model. I have several other UPS battery backups for my electronics and they all have an USB/RJ45 port with accompanying cable. There is software available to monitor and do a self-test on those units and other functions. Next the battery is sealed, no way to replace it. Haven't decided if I want to keep it.

    No, I would not recommend this to a friend
