I thought I might help others with this idea of mine: buy this $19.16 DC 2 PD converter and use your Librem 13 DC charger to make it, use it as reliable (some other converters might not be usable) PD3.0 PPS source. Please let me know if linked W20-100W converter from WITRN helped someone indeed. And, if someone needs (searches to buy) two PD3.0 output ports converter just let me know.
