Customer Ratings & Reviews

Lighting hit the DirecTV dish and took out the DVR unit. It would have fried the computer but it only fried the CyberPower - 650VA Battery. Saved thousands plus all the data. Getting one after it hits is too late. Keep in Central Florida is the Lighting Strike Area. You will be hit at some time. Be ready.

Works perfect and super fast service from Best Buy

Bought this for my office set up and it works great! Feel at ease and comfortable knowing that I have backup power when needed. It does beep a bunch when disconnected from power which is annoying but also indicative of power loss.

This is my 2nd time buying this, a must have if your like me and run a home business with multiple computers running at the same time.

This unit has a higher capacity than most for the price. Plenty of plugs for devices. CyberPower has a very good software that can be downloaded free to check the operation of the unit and control the computer shutdown time in case of a power outage. It was very easy to install.

Nice UPS. Using it for power backup for my router. Decent number of power ports. I was looking for something more flat and small and this one did the trick. I have put it in my small corner table. Takes very less space and looks neat.

This works well as a battery back up for my computer. I have had the identical model before and it lasted for years. If the power goes off it gives me time to close everything out.

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

Our neighborhood has all kinds of power surges and outages. It has killed two computers to date. Bought this in the hopes it would give us enough time to turn off the computers if the power goes out. It works great for one computer. However more than one it doesn’t work. It has a powerful sound that it makes though. Overall great product. Just wish it would have worked for all our computers without buying multiple.

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

Easy to charge and setup. Holds to computers easily

I have no idea whether these (I bought two) are working WELL or not. They are working though. They are very convenient as outlets also.

Excellent product, I’ll buy again I’m in need. Peace of mind about my devices protection. My special thanks goes to Best Buy associate who had delivered to me at Best Buy store park in lot. Very gentil and courteous.

Had to buy another one because my last one died (after 12 years, good run!). Great to use with my TiVo or router to keep them from having to totally power cycle when the power dips.

I set this up with my cable booster, cable modem and wireless router. I am hoping that this will allow me to maintain internet connection while power is out for a few hours. Hasn’t had to be tested yet but we will see. Fingers crossed.

I needed a backup battery for my electronic equipment and this unit came through like a champ. My neighborhood occasionally gets brown outs and I had to continuously reset my electronic gear. Now thanks to the cyberpower I don't have to.

product works fine does the job cyberpower has performed better for me than other ups have added this to my win98se (!!!!!) system after a recent power outage reminded me that it needs protection as well as the xp (!!!) win 81 (!) and win 10 boxes

Works fine. Silent mode is a huge plus. The power LED is not the power button, so it was simple to tape over it without interfering with the normal operation. Therefore, I recommend for a bedroom if you're sensitive about lights. The two USB ports are nice, too.

this product provides the peace of mind that if the power goes out there's still the back-up battery. This is the second product of this kind I purchased for my small office space and for my other electronics. The cost was just right. Always reliable.

Easy setup and worked right away with no issues. Haven't had issues at all in almost a month.
