fast charging powerbank

I make this 12v 10ah powerbank with 2 type c module with maximum charging speed of 25 watt charging speed with both the output port and for input i used 12v barrel type plug so that i can charge it rapidly using 12v adaptor.

I used two alumminium heatsink for each module one on upper side and one on bottom side as this module heat a lot.

I am planning to add small fan for ventilation if i make that change then i will update that model.

parts i used are 1) 3pcs of 10000mah lipo battries 2)2 type c 65 watt charging module (u can find it on amazon easily) 3) 3S battery level indicator 4)3s bms for lipo battries 5) dc female jack and 4mm screws
