Customer Ratings & Reviews

Easy to charge and setup. Holds to computers easily

This Surge Protector has worked perfectly. We have regular Power Surges and Power Loses in our small town with all the power lines still hanging up in Telephone Poles. I work as a Realtor and Photographer and must be connected at all times of the day. I have not lost any of my Contracts, Videos or Photographs during Power Outages. I like the smaller size so it can sit right up on the desk and I plug my laptop into it.

I bought several of these to mitigate issues we have with intermittent electrical "outages" / blips. Even after installing a generator, the power would go down for 10 seconds until the generator kicks in. I put one in my bedroom, powering TV and other devices, another in TV room (powering TV and cable box), and the third in my utility room to power my master cable connection, internet modem, and VOIP phone. These only need to use battery for maximum of 10 seconds before my generator kicks in. While my Google wifi takes a few seconds to reconnect after generator kicks in, everything else runs perfectly. Great solution to my problem.

I have other cyberpower products and am happy with this one too so far. Using it on modem and router in case power goes out like it often does where I live.

This backup is slightly larger than I expected, but it works great. I can depend on it during any power failure to keep my TV, satellite, and computer on line. I also used it to keep my automatic pet feeder operating while I was on a vacation.

Thank you, Best Buy, for making online ordering and curbside pickup so easy with designated parking spaces and helpful workers right there to put my purchase in my car! Besides which, the backup battery system is working beautifully.

I'm very happy with my purchase. This protected me from at least three brown outs in the last few months since I hooked it up. It's plug and play in Windows 10 and Linux. The build quality is great. I would buy another if needed.

Have our xfinity Highspeed router/modem and our WD dual My Cloud back up plugged into this device and it’s performed very well. Had the power company install a new meter and they turned off the power and the device worked as advertised.

Good value and performance battery backup. Just not a visually appealing device. Has the basic features and has been working great.

Have had several CyberPower Back-ups, bought this one for my wife to use on Embroidery machine and associated computer. It has kept her from loosing work during power outages a number of times since we got it.

I purchased this product to replace a back-up power supply that needed a new battery. The price wasn't much more than replacing the battery on the old unit. this one is easier to set up and connect to the computer than the previous unit.

very good I like still working perfect and is very easy to conected with all electronics

Came in handy at just the right time; we had a thunderstorm a few weeks ago, the power went out and the battery kicked in just in time for me to shut my computer down properly. Saved me a lot of toil.

Very handy as Edison outages often in my neighborhood with this E battery Bank I never loose my shows

This is a replacement for my old 8 year old model. Works well and set up was easy. Use on PC now and will order a second for Wi-Fi very soon. My old model was a 450A and this gives me a little more time.

Awesome device and great warranty. Love that my pc will be protected

This CyberPower - 650VA Battery Back-Up System very much enough for the whole home office protection

This battery backup works well and gives me enough time to save my files if we have a power outage. I can work for 5-10 minutes without power using my computer and two monitors connected to the backup system.

Thia battery back-up system is a must-have, giving me peace of mind during the fluctuating electrical network. It protects my important devices using the power lines. it is also easy to use and reliable.

Great price. Using with my Synology, Wi-Fi, and TV. Works flawlessly to this point.
