    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.

    A perfect fit for two light use computers i have running. This is my second purchase of this product. The other one runs a few tv's and worked as intended during a power outage. So giving it a try on the computers. About a month in and the power went out again during a storm. The computers were unaffected for the power flicker. Great product. Always check your power needs vs what the battery back-up is rated to handle.

    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.

    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.

    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.

    I was in desperate need of a backup battery and this one even came with a couple of charging ports for USB devices. A bonus! Yeah! Well done! I couldn't be more pleased with it!

    No electronic item should be without a battery back-up unit. Helps save the electronic device from surges and keeps your wifi up and running when the power goes out.

    We are planning a vacation and our 14 year old wants to set up his PS4. We had tried before and something with the car battery would make it shut off in traffic. This a great back up battery.
