Description

Previously we have made the [Power bank circuit][1] simply using Boost converter Module and TP4056A Module. But here in this project, we are creating a single PCB instead of using two different modules to charge mobile phones. Although the previous one was easy to build but this one is neat, compact and customizable. [1]: https://circuitdigest.com/electronic-circuits/power-bank-circuit
