I let someone look at my pinecil, they grabbed a standard 5.5mm 12v barrel-style power cable for the bench power supply assuming the pinecil used that standard and did the old push&twist to force it in.
After a few seconds of effort my associate had a stupid look on their face holding the connector cable but the center pin from the pinecil was jammed tight into the barrel connector.
Fortunately I was able to re-insert the pin and solder the broken power line back together, though certainly not as strong against a similar attack it works again over USB C (obviously) and the repaired barrel power port too so all is good.
