Customer Ratings & Reviews

It's pretty cut and dry. It works like a champ. I would prefer more battery-powered sockets and less surge-only ones, but it works as advertised.

Great product at a great price. happy with this purchase.

Use this to supply my wifi router and modem. means i have a few hours of wifi even if we lose power, for not much more than a standard surge protector.

Works great. I had to replace an older unit and this worked out perfect.

Needed a UPS for the occasion power interruption. Lasts about 15 minutes on my desktop PC - more than enough time to shut down without losing data.

This is a replacement for unit that died after 3 years. The dead unit never failed me when power went out thus another CyberPower. More features.

it does what it is suppose to do!! the salesperson helped a lot.

Make sure you understand the times it says it can power all your devices that you typically use. For my iPhone and laptop it lasted about a half hour, when buying it I saw 6 hours and didn’t see the little wrong that states itll last that long when connected to a router/modem and that’s it. I was going to use it as an extra power source for a enclosed area on the back porch but now it’s just a glorified, way overpriced surge protector.

Does the job at a decent price. In stock and easy to hook up.

I've used this brand and APC many times and they are both very good battery backups. The only reason I lean toward these is that APC disconnects the battery, which is good, but it's a real pain in the buns to reconnect it.

Easy to install and so far does the job well! We have experienced several brief power outages recently and the back up system has worked flawlessly.

Was time to get a new battery back-up system and this one was less expensive and more powerful than replacing my previous one with a same model.

This actually works good on my tv and electronics though by the way. They always protector my tv and my sound bar by the way.

Easy to setup and connect to my desktop power. This UPS will help preserve data in the event of a quick power outage. Would buy again!

I bought the CyberPower - 650VA Back-up System for my wife. Ihad just bought her a new $17,000 quilting machine. One of the owners of the store was installing it and said, you better have a good battery back up for this machine because if you had a power outage, even if you have a generator, because it can ruin the computer inside the machine. The CyberPower was the highest rated online and at a great price.

Replaced a problematic APC UPS with this and, as always, I am happy with the CyberPower product. Everything the APC product offers at half the price.

Works as advertised! Nice spacing on the outlets. Handy USB ports as well.

This was a great purchase, especially for a home office. After some power outages, it was an easy decision to make.

bought this thing for my modem/router from cox so that when theres no electricity I have my internet on for a few hours of connection.

Good battery back up. I had to purchase 10 of these at different locations, 2 of them were not working at all,I had to return/exchange them. Overall performance is OK, I would have to keep an eye on them to make sure they are stable.
