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.
Instead of XL6009 I suggest you use the MT3608 boost converter, it's much stable when the cells get low on power.
