Customer Ratings & Reviews

I have used this Battery Backup for a month with no problems. It quietly maintains power to my Internet modem with minimal heat. I have had no issues with losing power.

I've learned to use and recommend CyberPower UPS's over any others, especially the older, maybe more popular brand. I've seen their batteries last almost forever, and the units are cheaper than others.

Great little power supply for the price. We have sour power at our home and this fits perfect into our space.

Works easily with my Synology NAS. Just plug it in and change a few settings. I got it right before a big rain storm and we had a brown-out during the storm. It kept everything running!

I am using this UPS for surge protection and battery backup for my laptop and tablet in the event I lose power due to storms. It has USB ports for powering cell phones. It also has a cable to connect my laptop to check the status of the UPS. I recommend this UPS.

Excellent working gadget. Easy to install and high in price/value consideration. Just the right size and gadget for my specific need.

The pump in my aquarium is supposedly "self priming", but it was never able to start itself back up after power outages. I bought this after coming back from an out-of-town trip and noticing that the pump had stopped three days earlier (fortunately all the fish survived). Have not had that problem ever since. There is a bit of humming noise, which may or may not be bothering depending on your use case. For me the pump is louder so it doesn't matter in the end.

I purchased the Cyber Protection Battery pack while I was attending online classes and couldn't afford to have my access to the online platform disrupted from power loss. This product came in handy when the power in my area was disrupted. I was able to complete my assignments on-time

My desktop was giving a message that was identified by a Geek Squad tech that was still in the building. He knew that it was the battery that needed replaced. He recommended this battery backup to prevent that from happening that is excellent. I really appreciate his expertise and would recommend the system. Please thank and commend him for his good work. I appreciate his expertise.

Very simple and reliable system. It has enough outlets needed in a small business. It comes with an alarm that informs you when it’s battery does not keep charge any more. Very good price . I installed 2 months ago, perfect so far.

Purchased this basically to keep a water softener and dehumidifier from losing power when the electricity shuts down from storms, etc. I have a whole house generator but it takes a minute or so to kick in so in the meantime there goes my settings on the softener. It works very well and I have had no problems with it at all. It's lighter in weight than some of the other brands I own but seems to be just fine in quality. All in all I am very pleased with this CyberPower 650VA Battery Backup and would definitely purchase again if needed.

Plug recepticals are set far enough apart for most plugs. 4 backup and 4 surge suppressors is nice to have. USB chargers are nice bonus. Small form takes little space. Priced right for my office!

I bought this UPS in order to keep my WiFi system (Orbi RBR50 and Frontier router/modem) functioning during a power outage. As it turns out, we had an outage about a week later and the the devices remained powered up. I plan to purchase another one for the Orbi satellite. In addition, this CyberPower device is pretty identical to another well known UPS, but at a better price point, so I decided to try the CyberPower 650VA. The CyberPower device also has a lower profile than the other well known UPS. They’re both good products.

This was my first non APC battery backup unit I have purchased. Overall it is as good or even better then my other APC units I have. I am currently using three APC units and two Cyberpower units including this one and they are working great. I use this unit for my entertainment system which includes a TV, 5.1 Home Theater System, and a Dish box. When the power goes off I get about fifteen to twenty minutes of battery time which is plenty for me to get everything shut off safely. The unit also helps to cut down on power issues due to the royal area where I live. I would strongly recommend this unit for anyone wanting a safe way to shutdown their devices safely. This is a great option for PC users as well.

ie bene using this for nearly a month and it was a way better replacement to a older APC UPS if bugs get in this UPS its easy to clean them out with how this UPS is designed and i have used cyberpower in the past

This UPS is an excellent bang for your buck, frankly an excellent backup if you get down into the specs especially when you take a look at the price. Love this a great backup for all my network goodies

The back up is compact, affordable and dependable for both power losses and surge protection.

Quick shipping. This seems to be the right size for backing up computers and monitors so you have time to shut down during a power outage. Having a couple of USB ports is a nice additional feature.

Battery back works great. Just a day after plugging in the back up system we had a 2 hour power outage.

Nice UPS for power backup. Easy to connect then forget.
