    I have purchased a few UPS/Battery Back up over the years. Cyberpower is a good value.

    Good product for the price. A lot less expensive than some of the other bigger UPS units but meets the needs of a few devices for battery back up.

    Great Value As Battery Back-up For Echo Show

    I'm using my CyberPower Battery Back-up System as a back-up battery for the Echo Show I use as my alarm clock. This thing is dependable, and for over a year it has been backing up my Echo Show without being in the way. I've heard it kick in and start supplying power during a brief power outage. This product is a good value.
