Customer Ratings & Reviews

Had to buy another one because my last one died (after 12 years, good run!). Great to use with my TiVo or router to keep them from having to totally power cycle when the power dips.

Hooked it up to my internet modem. Now those pesky power flickers doesn't drop my internet.

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.

Great product, good price. Have used this brand for the past 20 plus years with no problems.

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.

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.

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.

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.

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!

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.

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

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

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

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.

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.

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.

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.

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.

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 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.
