Customer Ratings & Reviews

I purchased this when my 3yr old APC 450 died and the local store was out of similar APC units. CyberPower... what a piece of crap... dead in 4 months... the battery no longer holds a charge and immediately drops any load in a power event. Will never purchase this brand again.

not the longest lasting but it was very cheap when on sale

I was only given 16 days to return this. We purchased this for our new server that we had new software installed on for the company. Once we had everything installed, we realized this was not sufficient for our server during power loses. We realized this 20 days after purchase. We are just at the 30 day mark after purchase and I have been trying to talk with someone at best buy and all I get is "rules are rules" and we can not over ride it. Fine, this will just mean our company will take our business elsewhere. Im very dissapointed in the 16 day return policy. This is ridiculous.

Solid product at a fair price. Plenty of outlets for electronics. Orientation of outlets is problematic for AC adapters. Overall I'm satisfied

This CyberPower 450VA battery back up would not power up. i tried the reset button. I held the button for 2 sec per the instructions but nothing worked. I've owned CyberPower backup before and had no problems with it. I returned this one for a refund.

This is a great product for an area with multiple devices and equipment.

Absolute trash. Could be a nice paperweight but cord makes it difficult to have a desk. Didn't work out of the box and Best Buy refuses to take it back and CyberPower's warranty service is a joke.

It was on hand, powerful enough but affordable for my needs.

Not the product I wanted. On-line help from Philippines. Impossible to reach local staff by telephone resulted in wrong product being purchased.

Can make your stuff safe in power outages and safe wiring

Less than a year later this device stopped functioning properly. Constantly flipping over to battery despite the fact power has not been lost and battery dies after a few seconds.

Brooke quickly. Wasn't strong enough for what we were using it for even though we asked. But without even losing power it quit working.

I bought 2 of these units. One was defective and never came on. The other runs for 2 hours then turns off. Very disappointing as I had bought them when I travelled abroad in an area where we experienced constant blackouts and needed these to protect my electronics.

Thrown out money. It won't keep up a small form factor PC and a single monitor. Every morning it's screaming in pain. Sad part is the computer was off. Hold the button and restart it and it works till the next day. 450VA should have been more than enough especially with the current on. Couldn't return it because of the pandemic so it's good for keeping a clock radio running . Like I said get a bigger one or get an APC.

Biggest piece of poo that I've ever purchased. I needed a surge protector and battery back-up for an overseas trip. Straight out of the box the battery was dead, and the surge protector side died two days later. Buy at your own risk!

Died in less than two years. Called the warranty number and left a message. Never got a callback. Warranty will expire in days now. Not worth my time for a $50 piece of junk to hunt them down.

Works like it’s supposed to. It doesn’t take up a lot of space like the others did with less power ratings.

This power backup has suitable power for the few critical devices that don't already have a builtin battery.

it does not hold in place on the wall and loses its connection with the outlet. Poor design

Unit works as advertised. Just as it should! It is black and has a green activated light!
