Mid-range battery backup. Adequate. Would by again.

Glad to have! Came in handy on more than one occasion. Other brands may be less.

After trying other brands I have found that Cyber Powers tend to last longer than their competitors.

Looking for enough battery power to allow home NAS to shut down smoothly when the power goes out. This 650VA has just enough juice to allow about a minute of run-time while server shuts down. Have one on the home NAS and got another one for my son's gaming computer so he can avoid issues from hard shut-offs.

This was a like kind replacement for an old failed battery back- up, and to date has functioned fine as it should for several years.

A battery back-up and surge protection system is recommended for digital audio mixers since they operate much like computers. I've tested the system and used it on a job and it works, it keeps the equipment running after power is shut off. I like the features of this back-up, improvements over the earlier versions like usb charging ports. If the battery lasts a while, I'll be happy. My only issue is that the battery is loose inside the case while an older model held it's battery tight.

This item performs exactly as expected for the price

I have no problem. Easy to install battery system is working alright. I am happy with product and the service. Thank you.

Solid device to save router, computer and other valuable devices from problems with power. As an option it has USB output to computer to initiate graceful computer shutdown over USB if a blackout will happen.

The CyberPower 650VA is a budget model and therefore it does not have a long battery battery backup time. However it is more than enough time for my use! I just need enough time to turn my system down, before I lose any work during a power outage! I'd give it 5 stars, if not for the plug layout. The plugins are up & down instead of sideways (See Picture of 650VA). This makes it difficult to plug in over sized plugs.

Bought a couple of these to replace the old 10 outlet unit that was getting overloaded quite a bit. Still monkeying with the software/control panel to get both units to register on the same computer, but all else is great.

This is used in my home office for some of the devices that if I loose power, would need to stay on. It has worked well, I can track the battery / status of the device and turn off the alarm fairly easily so when we loose power, it won't wake anyone at night. I'd recommend it.

While I haven't yet had a fluctuation in power since I bought this, it appears to me to have everything needed to protect my computer from being fried. I live in an old house, and already lost one computer due to power fluctuations. I feel I can rest easy with this device.

I've bought this product before. After several years ir no longer retained a charge. With a new TV I wanted the power protection, so I went with this quality product again.

I always use this product to protect my computer and some other things to take care of them from change of electricity !!

Able to run my daughter’s laptop while we are traveling down the road.

Good value for a product that you don't want to think about. Just plug it in and it works.

I plugged my DVR into it to keep the power steady. Without it even a very short power flux would cause my DVR to recycle, and I would lose a part of whatever program was being recorded.

Solid, no frills UPS. Good value. You can find more expensive UPSes, buy for many uses, this is ideal

works great have no problems at all save more space then my last band
