Small & powerful flashlight for emergencies

Hello guys!
I wanted to build a simple flashlight for emergencies. It's small and very handy in case, for example, of a power outage. I's also rechargeable and it was pretty cheap to build.

A big THANK YOU to all my patrons, especially to: Max Rice and Anthony Ortenzi.
