    I've been using Cyberpower battery backup units for years since switching from APC units due to to their high prices. Cyberpower units like this do all that I need them to at far lower prices.

    This is horrible. I live off grid and run a generator for 12 hours and have a small solar pack and I charge this backup for 12 hours and when I shut the generator off for the night I only get two hours of back up power and the only thing that is plugged into this unit is a modem for the satellite and it is 48 volts and 1.8 amps. In other words don’t bother with it. I will try and get my money back when I go to town in a few months.

      Hello, It is best practice to look at run time estimations before making a purchase. That being said, 2 hours with the load described exceeds the estimated run time expected from the SX950U.
      Also sounds as if you are attempting to use the UPS for extended run times. UPS battery backups are not meant for extended battery run time. They are designed to provide uninterrupted power so that the connected equipment can be powered off correctly.
      If you have any questions regarding the unit, please feel free to reach out to us at 877-297-6937. We'd love to hear from you. CyberPower

    I was very disappointed in this battery backup system. I worked great for about 4 to 5 months and then it would lose power. At first I assumed someone was accidentally turning it off but soon realized that wasn't the case. It stopped working. I would not recommend this battery backup.

    Only lasted a little over a year and battery failed. It started continually beeping, I tried multiple outlets and different houses to verify it wasn't my house electrical causing the issue. I'm not seeing many others complain about it so I must have just received a bad one. My experience rates a one star.

    Simply awful. After just over a year of owning this it blew up. I feel lucky that it didn't burn our house down. We only had our reclining couch plugged in, so it most definitely wasn't due to user error.

    Bought it in August 2020 and now, 6 months later, we have had a couple of small power outages (blip off then on) due to high winds and it has shut down both times! Waste of money. Never buying again.
