Customer Ratings & Reviews

Bought this because my APC went out. This one is cheaper and has more joules. Using for 3 months. Great

Does what it needs to do , use as a backup for a file server, Price reasonable for having peace of mind of a back up.

I have bought 2 of these and they work really well for protecting against surges and regulating power.

This battery has never failed during power outage... Always plenty of time to save and shut down.

Although this does provide good surge protection, the battery only lasted about a year do to short term power outages at my house.

My 650VA CyberPower Battery backup is just what I needed to protect my desktop computer. Simple to install, just plug it in according to directions.. In addition I signed up at CyberPower Website for the Power Panel. I experienced an electrical surge since I have had it. It kept the computer from shutting down suddenly. I am so relieved to have this protection with 3 year warranty on the appliance and the computer protection is good as long as I own this product.

But no fear with this baby hooked up. Been thru some bad storms and not a lost minute of play.

Wanted a UPS to power the Wifi and Router. This works well. It is reliable so far (I have an older model that is similar and that has been good too). No complaints. Nothing that makes this a particularly special UPS, but i like the spacing for the outlets and the fact that some are surge and others are battery backed up. I think it is a good value and i would buy again.

Easy to install and maintain. Gives confidence you won't lose whatever you are working on with the computer.

I wanted surge protection plus battery back up for my home computer and mycloud. This has been great so far

During two power failures my system was not interrupted at all, the unit worked seamlessly .

I was impressed with this purchase. My neighborhood has more than our share of poles being knocked down, taking out power at least once a month, even more during 'party seasons'. 2 weeks ago it happened again, but since installing this product, I had the time to back up the documents I was working on and did not have to waste the 2+ hours trying to reconstruct and retype them. I was very pleased with this purchase.

Compact and efficient. This covers the need to protect equipment from surge and brownout type damage.

I bought this because the one we had before finally crapped out after 10 years. What was really great about this is that it is a better model for a cheaper price than our last one. Very happy with how this product does its job and protects our computer and modem.

Previous unit worked well for many years. Provides a feeling of safety for computer and related items.

No complaints, works as advertised. This is my 3rd unit and I'm very satisfied with my purchase.

I love the cyber power battery backups they last U.S. Much longer than any other ones we've tried.

Works well and has not had any problems, saves you equipment, great battery backup power supply

This is an excellent unit. I never have to worry about power outages damaging my electronics

This brand is hard to find in stores,It is nice looking and does the job, cheaper than buying a new battery for the old one, batteries don't last forever. 3 - 4 years is about it. No one should run a desk top computer without a battery backup. My modem and router are also plugged in if a power failure or interruption happens to prevent having to re-boot.
