Customer Ratings & Reviews

So far so good. Easy to set up. Haven't had any issues.

We have used this item for years and it works well

Works very well for a backup battery for our wifi.

This Battery Back-Up is well-designed as to the amount/type of plugs and how it is laid out. Good instructions if you didn't know anything about a back-up, and very easy to use. I'd definitely recommend it to anyone!

This is my second one for the last 4 years. I have purchased for my home, mainly to protect my modem and security base, as well that my computer system and it works great! . This unit is definitely worth the money that I Paid for it.

I'm sure it'll work as well as the one I bought last year for my computer room, to even out power surges and dips. This is for the living room TV, 3D-DVD, sound system & cable box.

Works great, I’ve used other products from same company

Recently had a power outage and back-up allowed us to shut down the computers without hitch.

Very handy in a power outage as my street has power issues a lot. This is setup with my modem so I'm able to wrap up any work and alert co-workers of my power issues.

Works great for what I needed it for. Great power source and fixed the problem.

Perfect UPS for single computer. I especially like it's compact size.

Great invention - helpful to have when power goes out and all you need is a phone charger. Don't have to sit in your car now :) This thing is very substantial and feels like good quality.

This unit replaces a 5 year old UPS, has twice the capacity and cost half as much. Within two days of installing it, my neighborhood experienced a power failure and this unit performed flawlessly.

Great, worked during storms, give no problems. Will purchase again.

No more power surges in the living room I put this.

It does the job. Never know when you will have a power outage, this will keep things on for a few minutes. Ether A power is restored or B you have time to safely shut down the equipment.

Bought my second Cyberpower back up for another computer. I have had the first one for years without any issues. Excellent Versatel back up system to keep safe if the power spikes or goes out.

This product gets the job done. I do not like the fact that there isnt a visual guage of how much power you are using. I like that you are able to mute the alert sounds. Both sides of UPS should be battery controlled but for what its worth its a quality product.

Perfect for power brown outs. Worked just like I wanted. It keeps our internet on for the short times we loss power durning the summer.

Tested this 650va unit and it worked as expected. I Was able to use my IPAD wlth the plug disconnected from the wall. The best thing was that the outlets are aligned differently so that all 8 outlets are useable. My 2 adapters for the printer and the router did not block the outlets next to it like my old backup did.
