    Bought this to replace the 6 year old same item. Obviously since it was 6 years old, it works as it should for a long time!

    Whats to say? You want a good UPS to provide clean power to your devices, and CyberPower UPS units fit the bill perfectly. Don't just trust your expensive electronics to just plugging them into wall outlets, extension cords, or plain surge protectors!

    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).

    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!!

    Has saved my tv and Xbox the pain of restarting when power has gone out. Very much worth it! Might get another one to power my POE cameras.

    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.

    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

    Great for the slow to re-boot cable box

    We have always had issues with periodic brief loss of power in our building. They are so brief, that they only affect the cable box. However, it takes the cable box forever and a day to reboot, so I bought one of these for the cable box and one for the aquarium filter, because sometimes it won't restart by itself after a brief outage.
