Customer Ratings & Reviews

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.

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

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

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.

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.

easy to install and test. purchased for backup for my sump pumps

Our older back up went out with the last storm we had. This was an identical replacement. The previous one served us well, and I'm sure this one will also. It does what it's supposed to do.

it has a 3 yr warranty - battery average life 5 yr.

I use a battery backup surge protector for my desktop computer at home. Every few years the unit needs to be replaced when the battery will no longer hold a charge. I was delighted to see the price go down since the last time I bought one of these a few years back. I have used this brand in the past, with no problems.

Works as intended. Can't go wrong with this product.

Got this to fix my parent's old UPS. This is a way to keep the internet up when everything goes down during a brownout or blip in power. Theirs went south and this fixed it.

Right after we installed these there were lightning storms and we didn't experience anymore issues.

Simple plug and play device. This will handle a computer monitor and speakers for about 10 minutes to allow you to shut down and stop the brown outs that kill the computer boards.

My son had extension cords everywhere to plug in all his video game and tv items. This got rid of all the extra cords plus the battery back up and warning features on this is great!

Bought this battery back up system due to a recent storm damaged some of the pc hardware. So far its working out due to we had a power outage and the system worked accordingly.

At 650va this will not run a computer for very long. However, I use these for routers, modems, etc and they can last 6-12 hours for this application. I recommend at least 1500va for computer applications.

of course, this review is based on how well we think it will work under duress in a real life situation. Power stays on if you unplug the UPS so it seems to work under test conditions.

Excellent product; easy to setup and installation.

Replaces a dead battery on an old UPS. Hard to judge without a power outage, but it has the number of outlets needed and fits in the space desired.
