Customer Ratings & Reviews

Reasonably priced UPS. Using it to provide backup power for cable modem, wifi router, and laptop with external monitor. Have not tested how long it will last yet. Wish it had some display of battery status.

Good product but didn’t work for what I initially intended it for which was to prevent my 3d printer from failing due to power spikes. Had to get one that was 1500va

This is a good product. it was great to have during stoms to ensure work electronics functioned

This is a fantastic product and Best Buy had an excellent sale price. This is much better than just a surge strip.

I love this unit. It keeps all my connectors in a tidy space and the USB charger is fantastic. I no longer struggle with one plug taking up two spaces. Well-constructed and will last a lifetime

excellent source of backup power and protection. I have this connected to a few computers used to check quality of manufactured items and it has worked as expected.

It works great. We have a 600W PS gaming machine hooked up to it and it works great. We've had a couple of power outages and were able to power down the machine just fine.

Bought it after a lightning strike killed my PlayStation. So far, it’s done what I expect. Ow we are just waiting on another lightning strike to really test it out.

Well designed and stable, this battery back up saved my hide more times than I care to acknowledge. Well built, sturdy yet not too heavy!

So far so good. Installed software on my computer.

It give me peace of mind & keep my computer safe..

I like it. I have 3 of them in my house. They save me from outages.

I haven’t loss power yet, I bought for wifi / internet backup!

Works great, good for cell phone chargers where usb connects from the side, but vertically large plugs tend to block ports.

The CyberPower - 650VA Battery Back-Up System is just what I needed to replace another Battery Back-up that failed after 5 years.

Bought as a gift. Hopefully it will save my family member 158 dollars next time there is a power fluctuation.

excellent product, only the instructions are not complete but there is not much to understand to activate it

Device has perfect backup power for phone systems and related equipment.

Our power fluctuates from time to time and we need a battery back-up system at those times. This system provides the power we need so we don't lose important information.

Was happy with my last CyberPower UPS. It lasted well beyond the expected time. With this said, I decided to stay with the same brand when purchasing my new one.
