Customer Ratings & Reviews

Great product, good price. Have used this brand for the past 20 plus years with no problems.

Thank you, Best Buy, for making online ordering and curbside pickup so easy with designated parking spaces and helpful workers right there to put my purchase in my car! Besides which, the backup battery system is working beautifully.

Love it. Keeps everything I need running in the event of an outage. Live in a condo that does not allow generators so we use these to keep the wifi router running and charge phones if needed.

Gone through several power outages and spikes with no problems to computer or other electronics. Works as expected.

CyberPower 650VA Battery Back Up System is needed for all computers for home business or for personal use. If there is power outage you will need Battery Backup to shut down & save your work. Very well made and price is right. Highly recommend to all. Thanks

I'm very happy with my purchase. This protected me from at least three brown outs in the last few months since I hooked it up. It's plug and play in Windows 10 and Linux. The build quality is great. I would buy another if needed.

Have our xfinity Highspeed router/modem and our WD dual My Cloud back up plugged into this device and it’s performed very well. Had the power company install a new meter and they turned off the power and the device worked as advertised.

A nice small UPS. I needed one to replace my old UPS as it started going bad. This fits the bill and is almost identical to the one it is replacing.

I have other cyberpower products and am happy with this one too so far. Using it on modem and router in case power goes out like it often does where I live.

I purchased this product to replace a back-up power supply that needed a new battery. The price wasn't much more than replacing the battery on the old unit. this one is easier to set up and connect to the computer than the previous unit.

A great UPS at a reasonable price. Protects your TV's, computers, modems, etc. In Florida, think of the times that a lightning strike has caused a momentary power loss, that forces you to do a complete reset. All that is a thing of the past. Pay attention to how and where you are going to put it. Sometimes a smaller flatter UPS with the plugins on the top might be a better choice if it needs to stand behind the furniture.

Have had several CyberPower Back-ups, bought this one for my wife to use on Embroidery machine and associated computer. It has kept her from loosing work during power outages a number of times since we got it.

Came in handy at just the right time; we had a thunderstorm a few weeks ago, the power went out and the battery kicked in just in time for me to shut my computer down properly. Saved me a lot of toil.

In our neighborhood, power goes out during every storm, even if only for a few moments. We have several computers working for our business and even a short outage could cause a disaster! We have had no problems since we bought the product.

This product for cost versus risk is very well worth it the ability for your computer to be able to run untill you can save your work during a power outage or power flinker is amazing. product is easy to install, but does need 8hrs pre charge before using

This is a replacement for my old 8 year old model. Works well and set up was easy. Use on PC now and will order a second for Wi-Fi very soon. My old model was a 450A and this gives me a little more time.

This battery backup works well and gives me enough time to save my files if we have a power outage. I can work for 5-10 minutes without power using my computer and two monitors connected to the backup system.

Everyone should have one of these battery back up/surge protectors on their computer and all home electronics. It will pay for itself during one storm with a power surge. CyberPower is a good product with a reasonable price.

Thia battery back-up system is a must-have, giving me peace of mind during the fluctuating electrical network. It protects my important devices using the power lines. it is also easy to use and reliable.

Good value and performance battery backup. Just not a visually appealing device. Has the basic features and has been working great.
