Customer Ratings & Reviews

Good UPS, not a large capacity as my other one, but got this to keep my wireless online during a power failure.... just use it to keep my modem alive. If you experience long power outages, would recommend a larger capacity... but ours are most short outages.

Picked up one of these for store register, needed a UPS that would power sequence a computer in case of power loss (not available on smaller VA units) this also happened to be on sale. Have used larger cyber power units for our servers and they have been trouble free!

I had an old battery backup unit that failed after many years so I purchased my new Cyber Power unit and it works great I am very satisfied it was a good choice for me.

This is exactly what I needed. I plugged my router & modem into this so that I have enough time to save any online work I am doing before it is lost in the event of a power outage.

I own several UPS's, including Cyberpower units. Unit at my office suddenly died, so I ran out at lunch and bought this one. Powers my computer, monitor and printer. I'm happy.

I find this product to be of acceptable quality and serves its purpose. I also note from previous purchases of the same product that it's "life" is as described in the warranty.

I purchased one of these back-up several years ago and I was completely satisfied with the product.

This unit is ideal for a small home office, and has ample support for computer, monitor, printer, aux. sound system, modem, router, desk light and accessories.

I have several of these 650VA Battery Back up for all of my computers, Yes I have 5 , and it's kicks in automatic , when you get a power loss. or spile in the line.

We needed five of these for our office, and it didn't break the bank to purchase them. We have power interruptions fairly often, but haven't experienced one yet.

Works as advertised. Due to all the storms we have been having in our area this has gotten quite a bit of use. The beeping gets old after a few minutes, wish I could figure out how to turn that off.

This is my second one, first one battery (4/2014) needed replacement and it was easier to get a new up-to-date one than to try to get and install a new battery.

This back-up system is very useful as it has many ports to power up many different appliances or machines at once. This is my second one like this - very happy!

This was a good value for the discounted price I paid. It could have a little more detailed description online and in the "manual" for those like me that know they need a backup system, but don't know enough to spend a lot of money up front.

if you dont have a ups, you need one. the last thing you want is your computer to turn off abruptly and have it possibly crash your hard drive

Purchased the UPS and connected all the devices. During a recent power failure, I had enough time to shut down all the connected devices without a problem.

This battery pack is a life saver when the power goes out. Granted it only lasts about 10 minutes, but it is enough to let me save my work and shut down the computer.

This is a replacement for an identical model bought several years ago. The UPS is used to provide battery backup to a burglar/security systems phone auto dialer. The auto dialer is in a separate location from the security systems battery backup

This is my second CyberPower UPS in 3 years. The first one failed right before the 3 year warranty period. CyberPower honored the warranty but the cost of shipping the device is about the same as buying a new one! Go figure. Overall solid UPS.

Needed a new one because of power surge in area, and my old Cyberpower Battery was beyond its life span and couldn't re-set! 10 yrs. old
