Powerbank module 134n3P / 1S 18650

This little thing takes one of the cheap eBay powerbank modules "134N3P" and clips to a 18650 battery holder.
Like this you can get a small powerbank for one 18650 below 1$.
My 18650 is salvaged from an old laptop battery...
... and the electronic of my module seems dumb enough to not cut off below 20mA.
So this powerbank is a perfect mobile power source for Arduino, ESP8266...
