Customer Ratings & Reviews

Just the right size for maintaining the internet connection.

It does supply power, but only for a limited amount of time

I purchased this item August 5th and it recently stopped working about two weeks ago.

I bought this for my iMac and Wifi router. My neighborhood has power outages for a few minutes almost weekly, and as frustrating as that is from losing unsaved work and rebooting time, I am fortunate this hasn't caused damage to my equipment. I feel much more calm having this battery in place; we've had several power drops in the weeks since I purchased this and I've had no downtime as a result. It's quiet, compact, and worth the cost. This model doesn't have the USB port that my computer can use to monitor uptime, and I regret that I didn't purchase a model that has that.

Small but powerful. Easy to use, small enough to not to be a nuisance, great surge protection, worked great during 2-hour power outage, affordable. Very happy with purchase.

This UPS power supply is one of best I've owned. It is small and can be put just about anywhere, plenty of outlets and two surge for more protection.

This is a great product. Compact, small. Good enough to keep my network hub, modem and nas working when energy goes off. This is the second I buy. Its features are all I need. And beyond the battery-backed up outlets it also has surge protected outlets. I just don't give 5 stars because the battery replacement is a little complicated. The battery of my first one laster +2.5 years - For me, it was worth.

This is reasonably compact for a UPS, and has enough outlets and battery to support a desktop + 2 large monitors + misc accessories in case of power surge. Reliable so far, but only had it slightly over a month. Will update with any issues.

I use this to keep my network router and Alexa running during power outages. I like that the outlets are split into 2 sections. One section is not part of the battery backup but does provide surge protection. I plug in devices in that section that I do not wish to have loading down the battery.

Of course! Here is a positive review you could use: **Title:** Excellent, simple peace of mind! **Review:** I got this to keep my modem and router running during the frequent power flickers we get during thunderstorms, and it's been fantastic. Setup was incredibly easy; I had it unboxed and protecting my equipment in less than five minutes. It's compact and sits right behind my desk without being noticeable. We had a brief outage last week, and it kicked in instantly, keeping my internet connection alive without a single hiccup. For such a reasonable price, the security and stability it offers are a no-brainer. Highly recommended for anyone who wants to protect their electronics and stay online.

Loaded it up so I know it will be good for about 15 minutes. Bought for bumps and surges. Printer, switch, two monitors and a computer. I have had two power bumps already. The lights in the house went off and on but the computer equipment stayed on without even a fade in power. It has paid for itself already. Normally buy APC but so far I am completely satisfied and I saved $10.

During storms, our power frequently “blips” - going out fo a few seconds at a time. While not generally an issue, this is highly annoying if watching TV as it causes the Roku or other streaming device to entirely reboot, often losing your place in the show. Enter this battery backup. I typically use larger backups (size and voltage) for my computer equipment, but it’s hard to put these in an entertainment center and they aren’t really needed for this type of application. This CyberPower device is the right size to tuck away in a (larger, to be fair) entertainment center and provides enough boost to get through these power blips without any resets. It works, doesn’t get in the way and doesn’t make itself known. Highly recommend.

I recently purchased the CyberPower Battery Backup from Best Buy, and I must say it has exceeded my expectations. As someone who works extensively on computers and values uninterrupted power supply, this device has been a game-changer. Firstly, the setup was incredibly simple and straightforward. I appreciated the clear instructions provided, making it easy to get up and running without any hassle. The design is sleek and doesn't take up much space, blending well with my existing tech setup. The performance of this battery backup unit is outstanding. During power outages or fluctuations, it seamlessly switches to battery mode, ensuring my devices stay powered, allowing me to save my work and shut down properly. The backup time is impressive, providing enough power for me to finish tasks or safely shut down my equipment. The additional features like surge protection and automatic voltage regulation add a layer of security for my valuable electronics. I've noticed a significant reduction in the risk of damage due to power surges since using this device. Moreover, the audible alarms and LED indicators are useful, providing real-time notifications about power status and battery levels, keeping me informed at all times. In terms of noise, this battery backup operates quietly, which is a bonus in a home office environment. Overall, the CyberPower Battery Backup has proven to be a reliable, efficient, and essential addition to my setup. It gives me peace of mind knowing that my devices are protected and that I won't lose work due to unexpected power disruptions. I highly recommend this product to anyone in need of a dependable power backup solution.

Easy to use and setup. Plug it in, wait a few hours, use with your stuff that you really don't want to shut-off unexpectedly. Power outages and surges happen with little or no warning but this will allow you to save and shut down programs to avoid damage or data loss. I have one for both televisions, computers, landline, and internet equipment. Plenty of outlets on the battery back-up to plug in multiple items. Lots of protection and convenience for not a lot of money. Good Value.

The compact back-up system fits perfectly on my desk behind the monitor as well as providing enough outlets to power the flatbed scanner, laptop large monitor, controller, and WIFI system. I'm hoping the new system works as well as my previous back-up system that ran trouble-free for 28 years. CyberPower made the old and new systems.

I have only owned this particular UPS for just about a month. It is the third Cyberpower UPS that I have owned but, this is the most basic of the three as it has no LED or LCD screen to tell you about the state of the UPS. However, I only bought this one as a safe-guard for the new TV I bought at the same time as this (in case of power outages and surges to protect the circuitry). Since only half of the inputs are both surge protected and backed up by battery you do want to take care that you are plugging in to the correct side with anything that you feel should have the benefit of having battery backup. As long as this works as it is supposed to when the power goes out I expect it to be of the same quality as the previous two Cyberpower battery backups that I own,

This is a decent UPS. Everything functions as planned, but there is a terrible beeping sound that never stops. The beeps are every 45 seconds and for the entirety of the power outtage. My wife and I purchased this for a daily power cutoff to keep our router on to work for 2 hours. The beeping sound drives us crazy but the UPS does serve its function. There should be an option to mute the beep. My guess is I need to open it up and remove the beeping sound for our own sanity. May be an opportunity for an instructional video. I don't need the UPS to tell me that the power went out. I need the UPS as a battery to keep my devices online.

Bought this due to recent short power outages. Wife works at home and when the power goes out for a minute or two all work is lost. This has saved her several times already. I am very pleased with its performance. Highly recommend this is you have delicate computer information and do not want it lost. Great product!

I have always been a fan of the CyberPoer battery backups and this one doesn't disappoint. I was looking for a smaller one to go into an IT wiring panel in a home and this worked perfectly, albeit tight.
