In this project I will show you how I modified a common powerbank in order to cut down its ridiculously long charging time. Along the way I will talk about the powerbank circuit and why the battery pack of my powerbank is a bit special. Let's get started!
Step 1: Watch the Video!
The video gives you all the information you need to modify your own powerbank. But during the next steps I will give you some additional information.
Step 2: Order the Components!
