    Excellent power back-up and protection. I used this as a battery backup for my home internet and Ooma phone. Never lose signal strength as long as the tower has power.

    Just had a major lightening strike at the house and purchased the surge protectors to replace the ones that got fried. The items that were on the surge protectors survived the hit. some may say these are expensive, BUT, if you have to replace all the electronics in your house compared to the cost of the surge protector. it is a no brainer

    Bought two of these because, as a remote worker, I need my computer to not shut off abruptly when storms are in the area. I have one for my work computer (bedroom) and one for the internet/wifi (living room). So far so good.

    This UPS is a life saver for those who do work from home. If you are working on a desktop, this is a must and it is adequate for one desktop, monitor and few external disks if you have. It is priced right, small enough to go under your desk and does the job well. Highly recommened.

    Perfect. 12/16/20 Had a power outage and this worked perfectly and quickly. I didn't even notice the outage until my son asked What happened to the light? It was a little funny, because I was still in the PC like nothing and I was like what happen? Until I noticed the outage. Worked perfectly. Now I need another one for my security camara

    I like Cyberpower's UPS lineup, it works well, their user software is solid, and they don't break the bank. With 4 Battery/Surge and 4 just Surge, this unit is perfect for a small home theater system or a regular computer (I recommend PC, Monitor, Modem, Router in the Battery side and any other peripherals like speakers etc in the surge side)

    Great little UPS backup for protecting my music recording gear and outboard devices while in a session. I protect all of my studio gear from under-voltage, dropout and voltage spike damage. This is just an addition to my other UPS units that keep my gear protected.

    Good Battery Backup

    I live in Florida where we loose our power on a regular basis. I have several battery backups throughout my house and have been lucky that my equipment attached has been saved when we have our lighting storms. CyberPower-650VA is priced right and lasts longer than most others I have purchased before. I would highly recommend as it has all the features and benefits of more expensive units.

    We have a bearded dragon lizard who’s on a timer that turns his basking and uv light off/on every 12 hours. But with the thunderstorms that take place out here we got worried that the power could go out while we were away and he may suffer with no heating. So we bought this backup to help out and so far so good. It does the job anytime we have power outages for short periods. P
