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.

    Using this with my Unraid NAS and a couple networking devices. Seems to work well with USB reporting load and capacity to the server. Haven't had an outage to test it in action yet though.

    I've been using this unit for about a month. No issues. I like the design with a smaller footprint, it fits well in the space between my computer and the wall. I can test the unit and see the event history with the CyberPower PowerPanel software on my PC.

    A slimmer version of my bulky older battery. Great performance, clearly marked surge sockets. Battery unfortunately has no phone jacks but otherwise fits the bill.

    Disappointed in plug spacing. Claims to be set up for “large plugs”, not necessarily. Barely got 5 items plugged into it. It’s a good thing that was all I needed to back up in that spot. Other features work as advertised.

    This UPS and it's slim form factor is a great option to put on a desk or entertainment center where space is premium. The 2.5amp USB charging ports are great for phones as well. Overall it's a must have when looking to protect your electronics. Highly recommended.
