Trying to find some type of power source that I could charge and then use to plug in things like a soldering iron, a laptop for to test posts, and maybe a light once in a while. I've really only have found UPS's and I'm not 100% sure how they work other than if the lights go out they can keep everything running for a short while. But I'm just looking for something I can plug into the wall overnight then take to my workbench area until I have a power outlet installed. Fire regulations in my are don't allow people to run power cords over 15ft apparently. So trying to find a battery powered option atm.
