Elegant Powerbanks using Disposable Vape cells (No BMS)

It is not a secret that the cells in the Vape cells can be charged. Some people power houses with them, some create huge power banks. I was wondering if there is any easy way to create some power banks from them so here we go. I tested 3 Modules, all 3 Delivered results as expected. You will need just this:

Universal Module: https://s.click.aliexpress.com/e/_c3NXuRSb
Smart Module: https://s.click.aliexpress.com/e/_c3DEzvRl
Minimalist Module: https://s.click.aliexpress.com/e/_c30wyUxh

And the corresponding files for Universal, Minimalist, Smart Power Banks

The video was uploaded in February but I use these power banks every day, they still work! The cells look good and they are FREE!
