DIY - 15000mAh Power Bank - With Salvaged Batteries (gets charged with 3A)

Hello and welcome back! In this episode I will show you how to make a 15000mAh power bank, which is very small for its capacity and it can be charged 3 times faster than regular power banks.
I suggest you use the smaller step-up converter (link bellow), it's much stable when the cells get low on power, than the one I use in the video.
