Customer Ratings & Reviews

I have never had this product before, but now it has given me an extra layer of confidence and peace of mind with my computer safety. It's working well so far to keep several lower-powered devices (NAS, router, and ISP modem) online and to allow an NAS to gracefully shut down when utility power is lost. While one can plug desktops and other high-power consumption devices into this UPS, they may not stay powered by the battery for long. The outlets are spaced slightly more apart than those in more expensive and capable UPS tower devices. However, for some, the orientation of the plugs themselves may require using larger plugs or wall warts on the top or bottom outlet. The solution, which I assume others do with other UPS units, is to buy very short extension cables that allow one to use larger wall warts. Battery IS user-replaceable. The USB outlets ARE powered by the unit's battery when utility power is cut off. The Synology DSM program will properly utilize this device when a USB cable is connected from the UPS's USB data port on the side of the unit to the Synology NAS's USB port. It networks all my devices, and I shall have to get another. Thanks.

I have had quite a few backup systems over the years, but this has the best combination of outlets and stats in its price range. It had an opportunity to prove itself a couple of weeks ago when the power went out. I was able to finish up my work on the computer (iMac) and save with no issues. Here's a little tip for all backup blocks where space for various large plugs and bricks cannot find a home: I bought a six pack of cord extensions for cheap. They are basically a six inch long extension cord that gives you just enough length to allow you to use just about any size brick with no problem. Just search around for them. The photo shows the unit as part of my cable management system.

Really handful and compact, no issues so far, i have to take care of my equipments because of the hurricane season.

I added a second security system to my house and bought this backup power supply on sale from Best Buy. Although it is smaller and less capable than my other uninterruptable power supplies it works great for my living room TV, stereo, and accompanying camera system. Plus, it is slightly smaller and fit perfectly in the entertainment system.

As described, reliable back up. Good price, practical and compact.

Perfect for connecting your living room appliances, besides giving you peace of mind with the protection to your electronics.

Good price and it works great especially with 6 plug ins.

Works just fine. Haven’t had power outages with it yet.

If you do not have a UPS connected to your computer, you need to get one ASAP. These are vital pieces of equipment that can be the difference of having a presentation ready for work or having a corrupt file. I have learned this from experience and now I preach the importance of getting a UPS. This system features 4 sockets that are battery protected and 4 that are just surge protected, as well as 2 USB Ports. These gives you a wide selection of ports to fit into any desktop configuration. Personally I would have the PC and monitor on Battery, and mostly everything else on Surge Protection. This will allow the maximum runtime for you pc so you can save and safely shut down the machine. You can also set up, with software, the ability for the UPS to trigger your computer to shut down automatically. Overall, if you are looking for a decent UPS that isn't going to break the bank, this is a great option.

I’ve been using the CyberPower 650VA Battery Back-Up System for a while now, and it has exceeded my expectations in every way. Setup was incredibly simple, and the unit is compact enough to fit neatly under my desk without taking up much space. What really stands out is the peace of mind it provides. During short outages and power dips, it kicks in instantly and keeps my PC and networking equipment running without a hitch. The audible alerts are helpful but not annoying, and the display indicators make it easy to know everything is working properly. The build quality feels solid, and for the price, the value is outstanding. If you need a dependable UPS for a home office, gaming setup, or even just protecting your electronics, this model is a no-brainer. Highly recommended!

I have purchased 2 of these in the past and had to replace one after over 3years of constant use for my work come home office. It only has a few battery backup and surge protector plugs but all of the plus are surge protectors. I am I Georgia and we have tons of Thunderstorms. While this has alarmed multiple times I have never lost anything plugged into it.

I got this one for my mother. I've set it up with her phone and Wi-Fi router plugged in as well as her PC. Helps to have the bases covered during an outage or just a flicker and definitely a surge. Good pricing and will last several years. Well with every penny. I've owned one myself for a while now.

Works great, i use it because i have a gaming pc and power goes out sometimes. This protects it.

All Good Work Great and Small, Liked a lot .... Good Price too

We are pleased with this Battery Back-up / Surge Protector for our Internet Modem, our Wi-Fi unit and our laptop computer. It is a good size and easy to use. We feel we are ready for the next power outage -- we will have enough minutes of back-up power to be able to save what we're working on on our computer and keep the modem and wi-fi going while we methodically power down our computer.

Easy to use and worked like a charm with a power outage the day after I hooked it up. Surges and brownouts are hard on sensitive electronics. Worried about my smart TV, and already lost one ps4 to surge/brownout issues I brought this home to make sure to prevent future damage. The battery backup lasts long enough for me to play for a bit, or safely power off my electronics until power is restored.

Works great and is a great size. Needed a smaller one than my last one while still having a selection of plugs and computer control.

I needed to provide surge protection and emergency power for my modem, router, cable set top box and large screen HDTV in my family room. I have lost power at my house several times during heavy thunderstorms and tropical storms. This power back-up product protects my equipment against power surges and also allows me to keep my internet modem and router up so that I can use my battery powered laptop PCs and keep my phones charging via the 2 USB charging ports during the outage time. My internet service is usually up unless it is a severe storm like a hurricane. You should get about 1 hour of battery when running wifi-router and modem while also charging/running one laptop PC according to estimates provided with product. I have not yet run for more than 1 hour on the unit's battery backup. At this price and size, it is not meant to run a large amount of electronic equipment. It does provide you with some operation time and adequate time to safely power down your plugged in equipment if a long power outage is experienced.

This is crucial for protecting sensitive electronics, such as computers, gaming consoles, and routers, from potential damage caused by sudden power surges or dips. One aspect I particularly appreciate about the CyberPower 650VA is its audible alarms. They are not overly intrusive but provide timely notifications when the battery is running low or when there is a problem with the power source.

zero problems installing and using it. I wanted to protect my TiVO, TV, and PC that is used for media streaming. I like the small profile of the device. I have a bigger battery behind my home network. This smaller device prevents momentary power problems.
