Emergency Micro Powerbank

Hello Everybody! I’m Manuel and in today’s project I want to show you how to make a tiny emergency powerbank that could potentially save your life!
We all know that our smartphone’s battery is always out of juice when we really needed it, for example to make an important call or, in the worst case, to call for help or rescue.
So, in order to overcame this eternal problem I designed and built a powerbank that you could attach to your keys or throw in a pocket and it will be always ready to charge a little bit of your smartphone battery.
Let’s do it!”
