    Great UPS device for the price and appears to be more energy efficient that other models use in the past. This UPS device does not appear to stay warm as older models, based on the circuit design.

    I have 2 computers that I can't afford to shutdown. This unit provides power backup for both computers as well as my modem/router with no problems at all. For the price, you can't beat it!

    Happy with purchase, super price, is working with no problems - which is what you want with a workhorse product, even if it isn't a "bright shiny object".

    We get brownouts every day. This helps protect equipment to avoid major problems. All my electronics have this or larger UPS units to protect it. A lot cheaper to buy these than replacing a TV

    I got this for short term power outages. Typically, the outages are few and for less than a couple of hours. This battery backup is perfect to keep my computer and my phone running for those short outages.

    I just use this for the base unit of my security camera system to ensure it will continue to work in the event of a power failure. I have the cordless phone base unit on this as well. I have a similar unit on the router and modem in the other room. Just a little bit bigger unit than this. Now power flickers won’t reset my modem and I have at least a limited amount of backup for the WiFi needed for my camera system in the event of an outage.

    This is a solid Surge Protector with Back-Up-Battery. Usually looked over by novices, but highly recommended by the pros. Helps avoid network issues when there is a power outage and avoid pointless calls to your ISP

    I bought the battery backup in case we have a power failure. The size is small but fits my needs since I don't connect a lot of electronics to it.

    works great to keep your equipment on when power goes out or you have a power surge. Gives you enough time to shut things down if power is going to out for awhile.
