In this project I will show you how to create a Laptop PowerBank. It mainly consists of a Li-Ion battery pack and one buck and boost converter. This way the PowerBank can get charged up through the Laptop power supply and aftewards charge up the Laptop directly to give it an additional run time of 3 hours. Let's get started!
