Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    These work great. We use it to keep our Satellite TV receiver from having to reboot during a short power glitch/outage.

    Overall form is about the same dimensions as a typical UPS unit, but the vertical design has a smaller footprint for a smaller place like I have. Price was great, also. Rated only 4 stars because I've only had unit for a few weeks and has yet to be tested in power failure.

    I have this one connected to my router, mainly to avoid the rebooting issues when the power flickers but doesn't stay out. This was a good deal for that purpose.

    Connected to TV and cable box. Lost power due to a blown breaker and it worked perfectly to prevent power loss to connected devices until power was restored.
