Warning, 5.5mm barrel-style power cables - biketool - 02-26-2021

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.

Pinecil DC Jack is 5525 type which means 5.5OD 2.5mm ID, don't force jam the 5521 plug. The 2.5mm ID stick is too large for 2.1mm ID hole.

Read the Pinecil label, clearly stated 5525 type

That person breaks stuff, but IMHO worth posting the warning not as a complaint but as 5521 is common and plenty of stuff breakers out there will not read or understand the label.

Original planning is using 5521 socket instead of 5525. However, there is no 5521 type for such type of socket :-(
