In this project, I designed and built a Portable Modular Solar Power Supply using custom 3D-printed parts, a lithium battery system, USB-C charging, and adjustable output modules.
The system can be charged using both solar panels and USB-C input. The adjustable solar panel mechanism allows better alignment with sunlight for improved charging efficiency.
Depending on the selected DC-DC module, the system can provide different output voltages such as:
• 5V
• 6V
• 9V
• 12V
Features:
• Portable and compact design
• Adjustable solar panel angle
• USB-C charging support
• Battery level indicator
• Reverse current protection
• Modular output system
• Fully custom 3D-printed enclosure
