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.

    I have 2 of these. This one is my UPS for my internet setup in the central closet. Backs up a modem, router, 16=port switch, OTA antenna splitter, and an LED light. Solid, reliable, and cool running. No complaints at all.

    Thin Design is Clutch

    Ultimately, I went with this slightly more expensive battery backup surge protector because of its sleek slim design. Having the ports facing upwards and thin enough to squeeze behind your TV or computer stand is extremely convenient. Works well so far, and battery worked seamlessly when tripping the breaker. I currently have a Sony 65" LED TV, Playstation 4, cable box/router, Nintendo Switch, controller charger docking station, and a Vizio soundbar all connected at once with no issue.

    Brown Out Reboots

    Living in Central FL, brown-outs & minor power losses are a fact of summertime. Sudden & frequent afternoon thunderstorms can reek havoc on your TV enjoyment. And when your power stops, even for a few seconds, your TV turns off, and your DVR/Cable Box may have to reboot. So, I purchased this item to prevent that from happening. It fits nicely behind the TV stand and has enough power for the entertainment system. It's a heavy unit, so I used the mounting slots to actually screw it under a shelf.

    So far so good. Fits exactly where I needed it to fit to protect my Wifi system and Network components during black/brown outs. I've had really good experience with other CyberPower Battery Back-UPS in the past and when I saw they had this slimline on sale, I bought it immediately. If you don't have battery backups at home, what have you been waiting for?

    Works great. We had some power outages within a month of getting this, and it gave me time to gradually shut down my computer and electronic devices. The plugs are also nicely spaced apart, and at least one bulky electrical adapter can fit without taking up outlet real estate. This is very useful feature.

    I am glad I purchased this battery backup system. I have had several power failures and this system has given me time to shut down computer before a hard shutdown occured. You can even set a duration of time for automatic sutdown of computer in the event you are away. Also battery supplies power during an outage to my VOIP phone that is commected to my wifi router.

    It’s a battery backup. They really either work or don’t. This is used for an electric lift chair. And when the power goes out you get a couple of up or down lifts. Which is really all I am expecting. There are bigger sizes that may last longer but I needed something functional yet not overly large.

    Wanted backup power for my in-wall networking equipment to keep my cable modem, switches, Poe cameras, and nvr running during short backouts. Got it placed in a metal 40x14 structured wiring cabinet designed to fit between wall studs. This is the only ups I could find that would fit. Liked it so much that I got another to squeeze in a tight area for my NAS. Purchased both on sale.

    A great thing to have if you only have a few things you want to keep running in case power goes out. I would only connect a computer and maybe two or three other less power hungry devices. Still, much better than running them on just a surge protector or power strip. You can also hook it up to a computer via USB and use cyberpower's personal powerpanel software to monitor all your devices power usage, set scheduling options, volume, etc.

    The CyberPower unit is a sleek space efficient unit that does an excellent job. It has 5 battery supported and surge protected plugins, 3 surge protected only plugins and 2 USB ports. The unit comes with a very good price as well. I would recommend this as a new or replacement unit to anyone needing a battery backup.
