Introduction: Make Your Own Hand-cranked Emergency Powerbank

About: Awesome Electronics Tutorials, Projects and How To´s

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!

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!

    I remember watching a video on your youtube about that modified powerbank you did more than a year ago. The one where you 3d printed the case. I wanted to recreate it this time so I looked for the video. Is it not available anymore? I can't find it anymore..
