Hello everyone! Today, I'm excited to share how I built an incredible power bank featuring USB, USB-C, and Micro USB ports, along with a fast-charging option. This project is a great starting point for anyone looking to dive into building batteries, as it's both quick and straightforward. The process is simple: just connect all the positive terminals of the batteries together, then connect all the negative terminals, and finally, link them to the PCB board. Let’s dive in!

Materials needed:
18650 or 21700 batteries: about $12-20 shipped depending on the cells you choose
