    works as intended. Wish it would last more than just 10 minutes on battery but overall, I enjoy it and does its job.

    One of the worst UPS units I have ever owned

    My job over the last 30 has been to support the UPS systems for a billion dollar company. I know my way around UPS units of all sizes and makers. For my home network, I wanted to try Cyberpower as their reviews seemed ok. Well, reviews are wrong. This unit appears to work ok, but any power flicker causes it to shutdown all the outlets and then beep continuously. While my APC units beep once then reset, this unit keeps crying until I manually reset it. That is totally useless and frustrating during a power outage. I tested the battery and it is fine. My load is way under 40% of total load capacity. There is only one indicator light and one button, so I have no idea what's going on with the unit. I'm replacing it with an APC today. CyberPower, please don't comment that I should call tech support. You know your product is junk so don't try to make it look like I don't know how to operate it. Just accept this as an honest review and make a better product.

      Hello George, Sounds like the internal battery in the unit faulty. The SX650U uses a lead acid battery which is the same as what you see for most car batteries. A battery can display good voltage while the capacity is bad.
      The SX650U comes with a 3 year warranty which would cover an issue such as this. Please reach out to our support team and we'd be happy to assist. We hope to hear from you! CyberPower
