Description
A useful usb charging bank with a flashlight. I used a 12 volt lead acid battery from an old car jump starter to power this beast. Its got 2 usb outputs with a total of 3 amps. But it splits it when 2 things are charging. I added a few 12v LEDs to the front for emergency light.
I added a basic wire diagram to the pictures. It's crude but it is clear enough.
