Customer Ratings & Reviews

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.

We bought this to ensure we were prepared for outages during storms However, its kind of like when your car is acting up and you go to mechanic, but it acts like the perfect child. Since the purchase, we have had numerous thunderstorms, but nothing that has knocked the power out. Go figure. At any rate, seems to be a good unit.

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.

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.

I love these little things. I use them as the stopgap for the cutover time between grid power and when my Powerwalls kick on. They serve the purpose of filling those microseconds when I don't want my Macs to lose power. Will they work for longer downtimes, probably not but for my use case they are cheap. They also have a +/- 4Hz allowance the Powerwalls use to shut down solar panels if I'm producing more than can be stored if I'm off grid. Feature wise there is enough distance between plugs for larger brick items, lots of space between the rows. Fairly light for having a battery in there. Overall great value for what they do.

I have multiple UPS units from CyberPower. All perform well. I got this affordable unit as a battery backup for a power reclining loveseat.

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,

I made an excellent purchase since where I live there are constant blackouts and the product is very good.

Love it! It is very useful to have the additional outlets and backup power.

This affordable unit is all I need for my desktop computer and printer. If I were a gamer I probably would want something with more power and additional features, but this is perfect for my specific situation.

It works well. I use it for my computer, printer & other things. I like that it has the power surge protector.

Very good product and no worry to replace my desktop's motherboard again though not hard

10/10 recommend, saw it on a YouTube video and got it, ever since my pc, xbox and monitor have been plugged in and has saved them a couple time after my house lost power like 3 or 4 times in a row, they stayed on a I just made sure to turn them off, also there’s an alarm that let’s you know if something is wrong

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!

Thought I was prepared with a automatic whole house generator. When the local Power Company. Experienced over 2 weeks of intermittent power failures daily. What you don't think about is that delay of 30 seconds. Between loss of power and generator taking over. That causes hard shutdowns of your system. This system is able to keep my desk top, printer and modem. All powered like nothing ever happened. Till the Generator can kick in so no more hard crashes. $45 upfront is a great investment. Compared to the cost of replacing or repairing sensitive electronics. Plus the built-in surge protection gives a piece of mind.

I have UPS Backup batteries all over the house. Everywhere there's electronic equipment there's a UPS. I have three (3) in my home office and needed one more. I'm not too particular on brand as I am on quality. I'd never heard of CyberPower, so when I noticed how reasonablly priced they are I had to do my research. I read a ton of reviews from Best Buy and the OEM in addition to the runtimes. So, I decided to take the leap of faith and go with an "unknown" brand. About two weeks after purchase we had some pretty bad weather and my power was flickering and later went out. I'm happy to report, this battery held up and I was able to continue to work without any interruptions. The lights were back on in less than 15 minutes and it continued to power my work laptop/docking station and three (3) monitors. The runtimes listed on the box are just an estimate. Depending on how you use your battery will determine how long it will last when truly needed.
