CyberPower - 450VA Battery Back-Up System - Black

They seem much smaller then the old ones and lighter must have a new type of battery. This is only a 450. I only have a desktop and a wireless modem plugged into it.. If you put anymore into this unit you will need a bigger unit like a 650 or greater.. I have a 650 one for hurricanes to charge phones there great for this.. It will also power lights if needed or radios or laptops or tablets. Desktops take to much power they will run the battery down in no time. . Laptops much better or tablets.

I plugged this in and let it charge up (Needs to charge 8 hours before use) then I plugged in 3 monitors and my desktop so it was not fully loaded. Then it started beeping out of no where and the beep stood for the battery being overloaded. So then on the website it said unplug everything then unplug it from the wall so it runs off the backup battery and if it kept beeping for the battery being overloaded then the battery has malfunctioned. Upon doing this it kept beeping so I promptly returned it and got a regular surge protector.

When the storms come that knock trees into power lines, the electricity will frequently drop out for only seconds at a time. It wreaks havoc on fine electrical equipment. For a very reasonable price, this backup bridges the gap between the loss and restore of those brief outages. My particular use is for my UV water purifier for my well water. It prevents the early demise of an expensive UV bulb. The price of this backup is WELL WORTH not buying new UV bulbs all the time.

Long power outages (5 to 13 hours) happen where I live as often as twice a month, and since we're in a dead zone for cell coverage we have to use wireless at home, so without power I don't even have a phone connection. This UPS is just right for keeping my cable modem, wired/wireless network and VOIP phone working during a long power outage. It's the kind of thing where there's not a lot to say about it. Either it works when you need it, or not. This works.

I purchased this to be the battery backup for my Cable Modem. It works perfectly for this and should easily keep it up and running for 30-45 minutes if I lose power. I sadly lose power for 10-15 seconds at my home at least 1 every month or so and this makes things easier. I highly recommend this and would buy again. If you look I did... I bought this the 650 and the 1500 model for other uses in my house.

I love in an area that sadly has too many surges and this thing has outright saved my work on my PC too many times to count. The loud beep will let you know it’s served you, it’s intense, but I’ll take a little shock knowing my gear is protected allowing me to save and properly shut down. This has a 15 minute back up, so you have plenty of time to finish work and save. Worth every single penny.

I have my NAS, router, and modem connected to this. 4 of the outlets are "protected" and the other 4 are running from the battery. These 4 battery operated are the ones that stay on backup. My only gripe about this model is that you can't turn off the outlets that are not on the backup. Since it doesn't affect performance, I'm not docking on the rating.

I bought this because I was tired of power flickers knocking me offline (really annoying when you are online gaming with a friend, and you just disappear for 10-20 mins. due to a 1 second power flicker). This UPS works as advertised. Just one problem, so far: I pushed the power button a bit hard one time and it got stuck. Had to disassemble the whole unit just to get it unstuck. Cheap design.
