For this project I built a fully functional laptop power bank from scratch. The power bank can charge laptops and other Type-C devices at up to 100 W and has the capacity to fully charge a MacBook air almost twice!
Technical Details
Power bank is composed of eight 18650 3500 mAh Rechargable Lithium Ion Batteries, arranged in 4s 2p configuration
Integrated USB-C power delivery protocol to charge laptops and other Type-C devices
Maximum power output is 100 W (20 V x 5 A) with 95 Wh of capacity
Custom 3D printed case with ventilation to prevent overheating
