When traveling, one of the most important things to remember is to get your phones and other gadgets charged. This is why getting a power bank is a necessity nowadays. However, a good quality power bank doesn’t come cheap. If you don’t want to shell out cash for a power bank, you might want to try your hand in making your own DIY mini USB mobile charger.
You don’t need a lot for this project. You’ll only need a 9-volt battery, a couple of bottle caps, a USB female connector, a voltage regulator, a 5mm LED, a 470 ohm resistor, and a 9-volt battery connector. Watch the video for the instructions.
