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.

    Sucks, always beeps warning ⚠️. Too much wattage. Get something better.

      Hello John, It is best practice to ensure the equipment being plugged in does not exceed the limits of the UPS. If you would like assistance with product selection, please reach out to our sales team at 877-297-6937 and we'd be happy to assist. CyberPower

    Has GNU/Linux Support

    So far, so good. I've only had this item for two months. I had two criteria when deciding on it: 1. It have enough backup power to keep a desktop computer and one monitor going long enough for a proper shutdown, 2. It has GNU/Linux support. Since my old backup power unit was only 250VA, this was a big upgrade with 3x the capacity. With the GNU/Linux software (separately downloadable and installed with a package manager), I am able to see that I have upwards of 50+ minutes, with my 550W power supply desktop and 24" LCD monitor, for a clean shutdown. (I was only hoping for 15 min.) The software allows scripting for shutdown, but I've yet to implement, as there's plenty of time to do it myself. Installation was as easy as plugging everything in, then doing a search for the software and installing it.

    Using this to power a desktop PC, Raspberry Pi, a small NAS, PoE switch and KVM switch in my office. Runtime is 17 minutes, even with this relatively large load. In addition to CyberPower's own management tool, the UPS is supported by the Network UPS Tools open source project. With that (and a little Python), I'm able to monitor the UPS with Grafana+Prometheus, and to have the attached devices automatically and cleanly powered up+down in the correct order in the event of a sustained power outage. Very happy with this solution and with the compact form factor. Only downside is that battery replacement may be difficult or impossible. Cyberpower's site says that it has to be done professionally and doesn't list a replacement battery.
