This is the last one I bought. I caught it on a good sale. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I bought this one in 2015 and it still runs good. https://www.amazon.com/CyberPower-CP...ywords=apc+ups
It depends on what you have plugged into it. I have my computer, Router and Phone plugged in and it says it will run about 20 minutes, but I have never run it till it shuts off, so I really don't know for sure. But, if the power goes out, it won't even flicker. I have it set to auto shut down in 3 minutes.
It will close everything and shut the computer down.
