I haven’t loss power yet, I bought for wifi / internet backup!

I use this for my WiFi router so when the power goes out i still have WiFi and if it’s at night it beeps so I can get up and call the power company and report the power is out

Good product but didn’t work for what I initially intended it for which was to prevent my 3d printer from failing due to power spikes. Had to get one that was 1500va

Well designed and stable, this battery back up saved my hide more times than I care to acknowledge. Well built, sturdy yet not too heavy!

excellent source of backup power and protection. I have this connected to a few computers used to check quality of manufactured items and it has worked as expected.

Bought it after a lightning strike killed my PlayStation. So far, it’s done what I expect. Ow we are just waiting on another lightning strike to really test it out.

It works great. We have a 600W PS gaming machine hooked up to it and it works great. We've had a couple of power outages and were able to power down the machine just fine.

I love this unit. It keeps all my connectors in a tidy space and the USB charger is fantastic. I no longer struggle with one plug taking up two spaces. Well-constructed and will last a lifetime

Device has perfect backup power for phone systems and related equipment.

Bought as a gift. Hopefully it will save my family member 158 dollars next time there is a power fluctuation.

The CyberPower - 650VA Battery Back-Up System is just what I needed to replace another Battery Back-up that failed after 5 years.

excellent product, only the instructions are not complete but there is not much to understand to activate it

Works great, good for cell phone chargers where usb connects from the side, but vertically large plugs tend to block ports.

Working well, as described. Have had several power outages, it has not failed to function.

WARNING!! DO NOT BUY!!! This is the 3rd UPS I ever bought. The first 2 were APC and I never had a problem with them at all. For years the APCs performed flawlessly. That's why I LOVE APC!! This time I figured I would try a cheaper brand since it's just to power little modem and router in next room. Wow, what huge a mistake! This thing runs out of power within 3 minutes now, and it's not even 1 year old. When I first got it, it would stay on for about an hour or more with just the modem and router. Good thing I got the extra coverage, I'm taking it back tomorrow and getting an APC with the in store credit.

works great just not quite what I needed I ended up buying a larger version of this and it works really good

i got two of these. i was able to mount it on the wall and save space. when the power went out my stuff still had power till the power came back on.

Was happy with my last CyberPower UPS. It lasted well beyond the expected time. With this said, I decided to stay with the same brand when purchasing my new one.

Our power fluctuates from time to time and we need a battery back-up system at those times. This system provides the power we need so we don't lose important information.

Great backup power supply. I use it on my satellite receiver and TV so it does not reset when the power is disrupted
