134N3P module Portable Li-Ion Charger/Powerbank

This is a portable, ANY Lithium-Ion battery charger/powerbank. It holds a cheap 134N3P module (sold as low as 4$ for 10x modules). Just solder two cables, hold them to a couple cheap little magnets and charge ANY LiIon battery or use it as a powerbank. It holds no battery, just a box with the electronics and cables with magnets. Easy to build and print, you got a portable charger and powerbank for the battery of your choice. Nice little tool !!

I soldered the terminals to some silicone cable
