Customer Ratings & Reviews

These provide excellent backup in case of power loss. I run a web server so when power flickers this prevents the computer from shutting down. Just plug it in like a surge protector, and you've got a couple hours of backup. It also gives you time to properly shut down your computer during a power outage. Another good use is having them with your entertainement center. Having a TV and Game system plugged in means during a storm or power outage, you can keep watching TV, keep lamps on, and generally still have power for an hour or so when the power gets knocked out. This won't protect you from extended power outages, but for short losses they are great!

works fine, easy to install, lightweight and small

Easy to use and great protection for house equipment.

These devices are super simple to setup. You don't even have to take it apart an plug in the battery anymore. Just plug in and go. We haven't tested them through a power failure yet so I can commit on the # of mins they truly last just yet.

I bought two of these for our house. We frequently have little blips in the power that cause our computers to turn off randomly. As a video editor this can be soul crushing. I am thankful I picked these up as they have saved me from losing projects. Happy to have these. So far no problems!

Excellent ups for backup of Internet modem. Keeps the the interent connection stable

Seems to work well as a surge protector, just wish it would keep devices powered on during brief power glitches. It only seems to keep devices on battery power when the power shuts completely off for more than a few seconds. But so far it’s protected my devices without any issues.

I bought it near the start of winter, the "slow" season. Now, we've already had a couple of thunderstorms. Usually I shut down during a storm. Not any more. Lost power once and the computer was on. The UPS made a click (same click when you turn it on/off) but the PC's monitor never missed a beat. Also, another time, there was a minor power dim. Barely noticeable, just one fast occurrence. My cable box shut down and had to wait for that to reset but the PC kept right on running. I'll never be without a UPS ever again.

Compact and extremely simple, good value for the money.

Easy to setup and use and very reliable. Very happy with this.

I like that there is a row of back-up outlets and a row of just outlets. There are enough outlets to cover all my power needs.

I have my NAS, router, and modem connected to this. 4 of the outlets are "protected" and the other 4 are running from the battery. These 4 battery operated are the ones that stay on backup. My only gripe about this model is that you can't turn off the outlets that are not on the backup. Since it doesn't affect performance, I'm not docking on the rating.

This is an excellent mini backup battery system with surge protection. Everyone should get one of these. It helps to protect your devices from a surge from black or brown outs. It also gives some back up to keep your device running.

Easy to setup, reliable and chirps when power is off. I enjoyed the placement of the different outlets.

Good product, bought it for modem and router and helped with power interruptions. Easy to setup and use.

Works perfectly. Plug in and go. No issues at all and inexpensive

This is a replacement for one of my CyberPower backups that the battery had died. I chose to replace it rather than ordering a replacement to save time and the hassle. I have used CyberPower backup batteries for some time and am satisfied with their performance. I use more than one for different devices pc,tv, etc.

It was easy to install and small enough to not clog up the cabinet. Be sure to charge itup before installation.

We live in an area which is prone to residential power interruptions. Our home security system somtimes requires a manual reset after power interruption so we purchase this product. To date it has functioned very well.

The Cyberpower-450VA Battery Back-Up System is great easy to set up plug it in and turn it on it will beep and set when power is turned on plug in your devices and you are safe in the event of a power surge or outage this is really a great device to have it saves your electronics from damage.
