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.

    Great UPS. Mac OS automatically detects a UPS with a USB connection without third party software, so I was able to configure shutdown behavior easily.

    All I have to say about this battery backup is that it worked fine during a recent power outage. It is bulky so beware of that.

    Bought this battery backup for - you know - backing up in the event of a outage. So far it hasn't lived up to it's claim. I only have one computer plugged in and some hard drives. And of course had an outage and this sucker didn't hold it's charge enough for me to turn off my computer. Luckily, my Mac Mini didn't have any issues - and now I'm looking for a better alternative.

    • Brand response from TechSupport
      Posted .

      Hello, Mac desktop computers use an Active PFC power supply which requires pure sine wave power. The SL750U is a simulated sinewave unit. If the CyberPower unit completely powered off, that is considered to be an issue. If that is the case, please reach out to our support team at 877-297-6937 and we'd be happy to assist. CyberPower
