Customer Ratings & Reviews

My old UPS died and I needed a new one. I have a couple of other Cyber Power Systems, so I bought another to go with them. This works great so far!

This back-up battery was a lifesaver this past week. The hurricane force winds knocked out power while I was working on the computer; was able to save all my work!

I needed to replace old back-up system for my computer, monitor, Wi-Fi, etc. This one is much better than the APC XS1300 that I had.

This is definitely one of the best items I have bought at Best Buy. It does exactly what it says it will do and does it extremely well. What more can one ask for?

Got this to replace older less powerful unit that would only last 5 minutes. This unit last for 47 minutes. It is a must have

this battery back up system has installed easily and is fully functional. thank you, best buy, for your speedy delivery service.

It's the CPS/UPS that I've been searching! I just love it! So far, I have not encountered any problems with the system. It working like a charm!

The PG&E has been replacing the transformers in the area and we had a lot of power shortages and brown outs. This device keeps my router and wifi alive. Apparently it does a good job, so far so good. I like the size. But I did not like the control panel and the connectors are on two different sides.

battery powered device to make sure you don't die when the power goes out and your life support is plugged in!

Great UPS. Performs well and is convenient to use. Haven't had any issues since purchasing it.

I would recommend it for everyone who works from home. Very reliable device.

I use these on every piece of electronics I own and have for long time. The last on I changed batteries was a CP 1350 and it lasted 6 years! I highly recommend.

I lose power ever time I have a storm. This was exactly what I needed. Keeps everything running long enough to finish what I’m doing.

So far so good. I use it for my CPAP, light fixture & cellphone charger. Hopefully it will stand up to the test of time.

I have used other Cyberpower units for years. Looking forward to years of use from this one as well

I've purchased this to backup and protect my LCD tv and even if it's big, the UPS can provide at least 20 minutes backup. I just hope the battery will last in time...

protects one of our oldest servers. this is the second we have purchased, surges & intermittent outages have not harmed our OLD equipment!

No poblems so far, I plug my modem and router in case something happens, it saids there it has 679 minutes in case of outage...

Sits on my desktop and handles two widescreen monitors, a desktop computer, a PS4 and a Mac Mini pulling about 500W consistently. Hasn't failed yet and isn't an eyesore.

This cyberpower battery backup was a perfect fit for my new system and did it's job well during a recent brown-out. Very happy with this purchase and plan to purchase a few more.
