Customer Ratings & Reviews

Daughter has thisnin her room for her desktop. Power went out and it notified her and gave her time to turn off her computer. Great product!!!

With the need to keep working on our computer after the power goes out, this is a great thing to have. Also prevents damage from a surge.

Works as expected and keeps the computer up whenever there is a power incident

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.

Just as good as the ones twice its size and capacity. takes up much less space on the PC desk. plenty of power to keep my all-in-one powered up until I can shut it down. and recharged both cell phones on the remainder of the battery charge before the power came back on.

The battery backup permits the continuous use of the internet modem and wifi during a power outage. This is important while switching back and forth between my solar powerbank and the electric company.

This battery backup system works perfect for my needs.

Had no problems so far. Power switched off and this still provided some power. Owned for a year or so alreaady. Will report back in 10 years if I am still alive or sooner if this thing breaks. I am relying on it big time.

Within 2 days of installing this product we had several small power outages which can causes the loss of the telephone and our local Private Wireless Network... This back-up system gives us time to bring the router and modems down and back up safely and quickly...

Given all the lightning we have here, definitely wanted to get one of these before we installed our new Samsung UHD TV. Has already been called into use and worked just fine. Least expensive model in the store. Replaced a more expensive APC which just up and died not long after the warranty expired.

We had a power surge and my other power strip “popped” and left a burn mark on the outside strip, and a bad smell. The lamp plugged into it and the phone were toast! This strip was fine and all of my equipment plugged into It was safe. Thank goodness! Will definitely be purchasing more for around the house!

Easy to use. Plug and play. Great value for your dollar

Just bought this last week and installed it not expecting it to get used so early, luckily I did because there was a winter storm that came through with lots of ice and my city lost power, thankfully my battery backup was still running and I was able to safely shutdown my computer.

Now that I am working from home, I needed to have reliable internet. This battery backup works perfectly when you get those short power blips that used to cause my modem/router to have to reboot. With this backup, I never miss a beat and can keep on working with no power interruptions.

There was a distant rumble of thunder during a recent storm that caused all devices, ie TV, lights to flicker & reset..Eveything came back except my Dell XPS which required a motherboard. I have added this device as a protective buffer in the incoming power to the XPS. UPS is a bonus and the unit costs much less than that $377 board..

Purchased the back-up system to use for my family room entertainment components to help with random power outages. Easy to use and works great.

I purchased this backup for a Ring home alarm base station. The base station has its own battery (supposedly good for 24 hours) but by adding this CyberPower unit I have a tremendous backup system. It is small enough to fit into a small cabinet out of sight. This is a nice small backup unit that works perfectly for low power devices.

I've had this same Cyber Power for the past 10 years which always protected my equipment, & I have quite a few power outages here in Florida. However, it finally went, so I replaced it with the same model which luckily was still available & hopefully will give me another 10 years of good service!

I have two of these battery back-ups, and they have been worth the money. They keep my computer running for a few minutes when the power goes out, which allows me to save all my work and shut down without losing anything. I highly recommend.

I bought this backup battery for my pc setup. Thank goodness I did. I recently had a rolling black out, in my neighborhood, and my pc stayed on. Thankfully the blackout lasted a second or two but I would have been very upset if I didn’t have this device, to protect my pc.
