    Every time we get new or more electronics, we buy a Battery back up system. At first we had the big expensive ones, but as we went away from a desk top we started using these. A very good size, Great brand, Great price. We have one for each tv, one for our modem, One for the wifes computer style sewing machines.

    Connected to the TV and cable box prevents the long restore when the electricity flickers. Surge protection is included to protect expensive equipment. If power is off for an extended time, controlled shut down also helps ease an unexpected shut down.

    This is a great small UPS. This one was purchased to support the network devices for a friend's home, keeping the cable modem, router, switch and WAPs running during power hiccups. Works like a champ. Was able to be attached to the wall to keep it out of the way.

    Living in Florida with our many storms you need a battery back up. This one will replace an older unit. It is sufficient to protect my computer and monitor and router. There is surge protection of other components as well. Very happy with my purchase

    This battery backup system is a replacement for a system that I had for several years. Was happy with the old system that was the same brand. The price on the new one was a better value than the old one. So far, this system is doing exactly as advertised.

    Awesome UPS

    I've only had this for a few days, but so far so good! I previously purchased an APC UPS that died within weeks, so I replaced it with this one. This UPS was reasonably priced and has a USB port (which is one of the reasons I bought it). You are able to connect it to your computer to initiate a safe shutdown, as well as monitor the battery life remaining on the UPS. After letting it charge, I unplugged it from the wall to see how long it would run. I get about 20-25 minutes with the following devices running off of the battery: Mac Mini, Promise R4 Thunderbolt hard drive system, TP-Link 8 port gigabit switch, Netgear AC1900/R7000, Phillips Hue hub, a cable modem (Motorola), and the Phillips Hue LED strip. My next move is to run my Ethernet through the built in ports on the UPS. If it doesn't affect my network speeds I will keep it that way for added protection.

    Recently, I purchased the CyberPower 650VA directly from BestBuy website. I was uncertain about which UPS would work best with my computer, so I used the online wizards at the APC site to help determine the best UPS. The wizard asks questions about the type of computer you have (tower vs. mini desktop), monitor size, and what other type of peripherals you might have connected to your computer.

    This is the 2nd battery I have purchased like this one.The first one lasted 5 1/2 years. Great battery. Our power is always blinking off. I have lost 2 computers from power surges. The computer I have now is 6 years old thanks to this backup battery.

    I previously used three of the CyberPower 625s. This is very similar. I really like the ability to easily turn off the power outage alarm. The alarm on a similar APC would drive you nuts. My experience is the battery lasts just short of three years. This UPS is worth its cost so that I don't lose the settings on some of my electronics.
