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 took this unit home, set it up, and 4 days later had a power outage! The CyberPower Back-up system kicked in and kept things running for over 45 minutes until the power came back on.

    Works as advertised: keeps the power going even with an outage. USB ports seem to work when they want to, with inconsistent charging power.

    No issues that I’m aware of. It does what it’s supposed to do. Protects the computer from power failure. I also have my cable modem plugged into it along with the Wi-Fi, so that I won’t lose Internet and my phone if the power flashes or goes off all together.

    Bought 2 of these units on sale. One for computer setup and one for home theater. Solid build and have already had 2 outages since I’ve purchased these. Worked flawlessly.

    I have been using battery back-up systems for about 8 or 9 years and have found them to be extremely useful for short term use in the event of a power outage and also surge protection. I have used both CyberPower and APC units in the past and will continue to do so.

    Great back up for your electronics. It even has a cable to hook up to your computer in case of system updates. Its taller than usual but takes up so much less space. Would recommend.

    Compact and does its job. This will be more than enough to protect your network appliances such as a NAS or router. It may not power it long, but it will power it long enough for a graceful shutdown.

    I bought this battery back-up system to replace an older model I have had for 20 years and had to keep replacing the battery. This new one is smaller, lighter in weight, has USB ports and works like a dream.
