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.

    I have been using this for my Laptop & main computer. Just this week I bought a 1500 model. I use to only buy the other brand (AP*) until we had a short power outage & the (AP*) almost went up in flames. It was behind my entrainment center & hard to get to.

    I got this for my PC (which broke, if you can read my recent reviews) but ended up using it as an outlet for my PS5 and other consoles - works great! I have bad electricity in my house, and this helps to “center” it! Keeps everything secured and safe

    It's pretty cool to have my computer continue to run uninterrupted every time there is a power outage or flicker.

    Cyper Power is easy to install and use. I am NOT computer smart to know about this need until a friend mentioned he had one. I looked at it and purchased it. I love it compact and affordable.

    Appears to be more than adequate for my needs. Have not had a power outage so far, so have not had to put it to the test. I'm sure it will function as it should.
