    I needed a backup power supply for my pc and Cyberpower 650VA fit the need. I liked that I can test the battery whenever I wanted through the app on my pc. It is smaller and lighter than my previous one from APC.

    This product was very well thought out, with sufficient number of outlets while maintaining adequate spacing. Also like the choice of surge vs. non-surge protection. A great value.

    You should always have your electronics on a surge suppressor, but nice to have things on back up battery so they are protected from sudden shut downs like desktop compters.

    Great little UPS Backup system - we got a few storms lately, and lost power a few times, one of those, damaged my Modem. Lesson learned, got this unit, and protects my equipments - not only that, in the last power outage, it last 4+ hours keeping my modem and wifi router without a problem!

    Replacement unit for an older one that battery died in. Cheaper to buy a new unit than buy a replacement battery. Got 5 years out of old one. If I get that out of this one I’ll happily replace it.

    The battery backup works great. There are enough outlets to plug in all components of my computer system. I’m hoping this will stop lightening from killing my new computer and printer.

    This inexpensive battery back-up unit is a terrific addition to my network as it helps to keep my router powered on and connected in the extent of a short-term power blip. I live in an area where we get occasional power disruptions, and I can stay connected without having to reconnect numerous wi-fi connected devices around my house. I have not tested the duration of the battery for an outage, but it met my primary use case for short and sudden power disruptions.

    This battery back up and surge protector had room for 8 plug ins and it lasts...this is our second one. The last one worked for years through lightning strikes. Very happy with it.

    Nicely priced, it works well with Windows 10 to keep your PC running during brief power outages and to a controlled shut down if the outage is longer. Works like it's supposed to.
