Mini 10W falshlight. USB C, adjustable brightness, Fan cooled

Simple and cheap 10w flashlight that fits 3x18650 cells but is also usable with any other lithium cells you might have around. No cells in series so you can just throw in any cells that fit inside.

Mine is printed from recycled plastic, that's why the color is so horrible :D

Parts used:

Thermal glue for fixing the LED to the heatsink: https://s.click.aliexpress.com/e/_DdWJytz

(you can also use a thin layer of superglue or similar. The heat output is small so it will work)

The battery gets connected to the charger module and the output of the charger module goes to the switch and connects to the input of the step-up converter.

Connect the fan and the LED chip to the output of the step-up module and turn the voltage up until the LED draws about 1A of current.
