So easy to use and very effective

We like these and keep buying them as the old APC ones die off. They are of good quality and last a long time before needing replacing.The plugs are conveniently placed so the plugs with transformers on the ends fit too. aEasy to plug in and use immediately, even though it needs to charge the battery, it'll still work (as long as the power doesnt' go out in the first 8 hours!)

I worked for 40 years in electronics. Cyber Power works quite well. The batteries in them last 3+ years, and they are cheaper than other uninterruptible units. However, Cyber generally lacks features that are common in APC power supplies. (I noticed they are changing and copying popular APC features and holding their prices lower). When Power supplies function well, I like to swap aging batteries for fresh ones. With APC, I had no problems finding the dimensions of their batteries and ordering them. I have some APCs operating for 16+ years, which I consider legendary. Legendary costs more. CyberPower sells for less. I use one 425W to maintain power interruptions from my internet. Light loads are handled well, but my main Peave with CyberPower are two things. 1. "No user installable batteries for the 425." (let me be the judge of that.) That is bull-puppy! The battery dimensions cannot be referenced in their 425 Watt. 2. CyberPower batteries and shipping cost more than buying a new unit. I hate to pitch a functional product in the junk because the battery lived to a ripe old age or faded away.All batteries should be easily located by dimensional searches. (They are not.) I have spent hours wasting away when a battery does the same thing regardless of how you shape it..

The electricity went out very briefly a moment ago. It’s the first chance I’ve had to see if it does work. And it absolutely does. I have a Mac Mini M4, 6 external desktop drives, and a monitor on the UPS side of the device.When the electricity failed, the unit gave a single beep, alerting me and giving me time to turn on the monitor and begin shutting down. Luckily it all came back on before that was necessary. But it would absolutely would have allowed for that much time.It’s affordable and well made by a solid company! I’m going to get a couple more for another cluster of computers.
