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!

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.

Helps give me peace of mind over my pc and other electronics. My power can go out every now and then, but this bad boy makes sure my pc stays on, so just really nice to have to ensure my pc doesnt get messed up.

Perfect back-up power system. I recently have the unfortunate experience of lightening striking nearby and frying my tv and cable box. This product gives me the piece of mind that my devices will be protected and that I can get items powered if electricity happens to go out.

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

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.

Good backup with plenty of outlets to plug in all of your appliances

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.

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.

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.

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

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.

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.

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

Works great. Just what I needed for my workstation to protect my computer against surge and outages.

Rather than use this as a backup for my computer, I instead use it as backup power for a lamp in my living room. I actually have three of them to backup all three lamps. Using LED bulbs in my lamps gives me about 8 hours of backup power to the lamps during power failures. Most power failures are over in less time, so with these units I have normal lighting through all power failure. But all of your neighbors will wonder why you have power while they don't. Reminds me a little of the episode of the Twilight Zone entitled "The Monsters are Due on Maple Street" However during the first 12 hours of charging the batteries you may experience a slight burning smell. Apparently that's normal.

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

CyberPower battery back-up system is easy to setup. Provides plenty of outlets for needed surge protection. System provides great protection at a reasonable price. Highly recommend the system.

Haven't had it that long but so far it has worked as advertised. Will probably add one more..
