In this project I will show you how to create a hand-cranked generator along with a modified powerbank. This way you can charge up your powerbank in an emergency situation without the need of a socket. Along the way I will also tell you why BLDC motors are terrible hand-cranked generators. Let's get started!

Supplies:

Step 1: Watch the Video!

The video gives you all the information you need to create your own hand-cranked powerbank. During the next steps, I will present you some additional information.

Step 2: Order Your Components!
