Mini Power Bank for Heated Gloves

To assemble this power bank, you will need a PB module modification that includes both USB Type-C and Type-A. The Type-A connector must be removed, and a connector of your choice should be soldered to the “+” and “–” pads.

The transistor and resistor next to the Type-A connector should be left in place.

The power bank can also be used without any additional power wires as a pocket power bank for charging a phone. In that case, you can use a module with only Type-C and solder only the battery to it.
