CyberPowerCP900AVR AVR UPS Battery Backup and Surge Protector, 900VA/560W, 10 Outlets, Mini-Tower, UL Certified

I have a game room in my 1940-built house. Now 6 players bring laptops and phones while my mini desktop runs 2 monitors and a TV. There is a ceiling fan and several personal fans while some people charge their vape batteries, since we are jn there a long time. My mini computer had power drops making it crash often until I started using this UPS. It's been smooth sailing since. I also purchased a wall mount for it so that people wouldn't damage it by running into it with chairs.

I have been using Cyber Power UPSs for several years now - moved away from APC because they reliably fail after 3-4 years (just after the warranty expires). The tower versions are very nice because the outlets are well spaced and easy to route the AC wires around/away from the unit. I highly recommend download and using the Power Panel software (I use the free "Personal" version). It tracks events (power glitches to full outages) and keeps history, so you can see when events happened even if you were not present.

Works great. There is a small hum from it, but it's not too bad. My original review was mistaken. It was a different device that is making the noise.

It's rather a sad indicator of the time in which we are living. We live in Sacramento California, which despite being the capital of the state does not seem to lend any importance to our local electrical grid. We suffer many more power outages then I ever experienced during the forty years I lived in So. Cal. While this situation doesn't have much of an impact on our lives, it has made for a number of nuisances, e.g. each time we have an outage at my mother-in-law's home, her Ring doorbell goes offline and when the power comes back on the doorbell can't seem to ever reconnect to the WiFi router on its own. She's in her 80's now, so it's necessary for me to get the system re-connected (don't believe what Ring tells you about it will re-connect on its own, this one certainly doesn't). We don't have a smart doorbell (we have a brass cat and it always works after an outage!), but we do have a number of PCs and other devices that are usually online, so an outage that takes out our router is a pain. For my mother-in-law I installed a CyberPower UPS (battery backup) that keeps her router up and running during the outages we experience. It worked so well that I did the same for our home. Now when we lose power our router stays up and working, making it much easier to power down our equipment if needed, avoiding lost settings, etc. So far we haven't had long enough outages that outlasted our UPS's capacity. I'm sure it will happen, but the difference having the UPS for us and mom has been well-worth the expense, and actually the expense is relatively affordable for these small units. My rack-mount UPS for our main PC was expensive by comparison, but it too is a CyberPower branded UPS, as are all of the UPS in our home. I've found CyberPower makes the most reliable UPS for most situations that the average person might have. Long ago when I used their name-brand competitor's UPS they failed on a consistent basis. I was lucky to have just one of their units live long enough to need a replacement battery, while all of our current CyberPower UPS have managed to do their jobs and live to accept replacement batteries when the original batteries came to their end-of-life. We did have to replace two CyberPower units after our home was hit by two different huge power surges. Those units did their jobs and protected our equipment. You cannot ask for more than that!

Added battery backup to my modem/router

This is a replacement for a 2018 unit in which the battery went dead.Purchased a smaller unit as the electrical load needed was less. Unit worked as expected.

Does everything I wanted

DefectivePurchased based on wirecutter recommendation but 1 month after purchasing (return window just closed) we had our first power interruption and the unit failed. Instructions helpfully said if you have this combination contact us. I expect my power outage tools to just work. Avoid.
