Customer Ratings & Reviews

We have quite a few thunder storms, with short electrical outages. My wify router reboots, interfering with phones, tv's, printer and anything else that uses wify. This has solved that problem. Very satisfied and happy.

We got this to replace one exactly like it that functioned well until a lightning strike took it out after 12 years - but it saved the PC before failing! Lifetime warrenty, too.

I have no idea whether these (I bought two) are working WELL or not. They are working though. They are very convenient as outlets also.

CyberPower 650VA Battery Back Up System is needed for all computers for home business or for personal use. If there is power outage you will need Battery Backup to shut down & save your work. Very well made and price is right. Highly recommend to all. Thanks

Gone through several power outages and spikes with no problems to computer or other electronics. Works as expected.

Perfect for protecting my laptop and Cable Modem for power outages until I can get my generator started and running. Good value for the money. Not for big Desktop Systems, but excellent for light usage. Recommend for intended use.

We purchased these after a short, quick, power glitch took out one of our computers. It was plugged into a power strip, but that wasn't enough for these quick burst. These little guys advertise they will protect us and so far, they have.

Everyone should by one of these Power supply, If sometimes trip your circuit breaker or have minor dips in power this will protect your computer, modem, etc. I recommend it I have had previous ones and they last for years.

I’m using this to counteract short power outages to maintain a WiFi network in our home. I have our modem, router, and MoCa adapter connected to the battery backup slots. This should be able to maintain internet in the house for at least 30-45 minutes based on the power usage of my devices. I’ll update my review after our first outage, to effectively provide a more accurate finding.

Immediately went on line after the first power blip of summer hit my house and knocked me off an important Zoom call. Delivery to my front door was a surprisingly 1 day and FREE. Easy to set up, plugged in my router and internet doesn't drop!

Came in handy several times during power outages. This one is used to back up our router and Wi-Fi extender so we don’t lose internet if the power flickers

Very nice battery backup for our router with extra capacity for other uses. Idea is to not lose our web connection during power glitches. Can also be used for backing up my desktop during critical operating times.

Sufficient plugs, USB ports as well. Easy set up. Tucks under desk nicely.

Works perfect and super fast service from Best Buy

Perfect for my needs. Just plug everything in and turn on.

A great UPS at a reasonable price. Protects your TV's, computers, modems, etc. In Florida, think of the times that a lightning strike has caused a momentary power loss, that forces you to do a complete reset. All that is a thing of the past. Pay attention to how and where you are going to put it. Sometimes a smaller flatter UPS with the plugins on the top might be a better choice if it needs to stand behind the furniture.

This is a high quality battery backup. It worked well during a power outage. I used it to back-up electronic controls for a hospital bed, I had enough power to lower the bed. This unit price was on the high side.

A nice small UPS. I needed one to replace my old UPS as it started going bad. This fits the bill and is almost identical to the one it is replacing.

I have had great battery life out of the CyberPower line of battery backup systems over the years, I decided to keep using CyberPower, when I replaced a many years old ups. Looking forward to long years of use with this one.

Love it. Keeps everything I need running in the event of an outage. Live in a condo that does not allow generators so we use these to keep the wifi router running and charge phones if needed.
