I Built a Solar Torch From Scratch — And It Works Amazingly!

Описание: In this project, I built a simple solar-powered rechargeable torch using a TP4056 charging module, a 3.7V 18650 Li-ion battery, and a 5V solar panel.
During the day, the solar panel automatically charges the battery, and at night you can turn on the bright COB LED using a switch.
It’s a beginner-friendly DIY build — perfect for camping, outdoor use, or emergency lighting.
