Compact Rechargeable LED Flashlight

Whenever I wanted to use my flashlight, it always seemed to need new batteries. I decided to make a small handheld flashlight that was rechargeable with any 5v wall chargers with mini plug. I wanted it to have minimal current drain in order to use it for days without re-charging. The following parts were purchased on www.aliexpress.com. TP4056 charger, 18650 battery and holder, slide switch. All other parts were salvaged and recycled.
