    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.

    I got a good deal buying an open box. I think they are worth it to have a little back up power to get a chance to power down some devices in the event the power goes out.

    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?

    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.

    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.

    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’m not pushing it too hard. But it does what i need, namely, keep the tv and switch on through a brief power outage. And Fits just fine attached to a wall behind the wall mounted tv.

    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.

    I live in Florida where we have monsoon season for 4 months. Florida has a state with the most lightning strikes of anywhere in the world! I need this to save my equipment for my home office. It was a little bit more expensive than some of the other models but because of the specs and the slim design it fits perfectly in my setting.

    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.

    Great gift. Rather large and heavy but plenty of space and no worries about unexpected computer shut down when power fails. Also facilitates cable management and helps keep work area tidy. The spacing of is well planned to allow for large plugs. Also includes several usb ports (no usbc)
