    Amazing outlet with lots of slots to plug in all of my devices, from my PS5, computer, and TV. Protect them against a surge and protects my electronics from damage.

    This is the second CyberPower BB we've gotten. First still going strong after 10+ years and numerous outages/brownouts. Works as advertised.

    Started working from home and wanted a battery backup and this is the perfect product. It not only offers a back up battery but it has enough outlets as well as USB ports. Mounted on wall with no problem.

    Device has already worked well with some electrical surges. The computer software is well designed and easy to use and lets me get an idea of the electrical draw of some of my devices, which is handy.

    Been using this for about a year now and it's doing well. I use the battery side to keep my WiFi router, modem, and security gateway active during an outage and it's been perfect for that.

    Power flickers often so decided to try this UPS for a PS4 and a 55” LG. It worked flawlessly when our power went out for about 5 seconds. I now have one for our internet and 2 desktops as well.

    I bought this to replace a 3 year old APC 600 UPS

    Purchased to replace a 3 year old APC UPS 600. It amazes me how they.can design the batteries to live until right after the warranty expires at APC. Of course by the time you buy the new replacement batteries and.pay.the shipping.your better off buying a whole new UPS. So after doing that several times with APC over the years I decided to try a different.brand and cross my.fingers it will last longer before it dies. It seems.to be working fine and.was easy to install. Time will tell if it works put better or worse than a similar APC. We usually dont have long power outages here just short ones. So they never have to work very jard or very long when you need them to actually perform their jobs here.

    I like CyberPower because they are reliable and when the batteries do go bad, they are easily replaceable. I also like CyberPower's software which makes programming auto shutdown times as well as email alerts really easy.

    Great batter back-up. Works well for several small electronics and keeps them running when the power flickers. If there's an outage it keeps things running long enough to safely power off.

    Works great!! Keeps my computer going without any hiccups if the power "blinks" and gives me time to power my computer down if the power actually goes off. Very good product at a good price.
