Modding the charger cable for a Powerbook G4 to USB-C

[headcrash]

So, shortly after I got my 12" Powerbook G4, I felt the need for more battery life, to make it portable for longer. So the obvious solution was to go USB-C PD to run it off a powerbank. This was a bit of a gamble, because the original charger is 24V, and USB PD is only 20V in my case. The charger cable is really thin and quite long though, so my thinking was that Apple designed it to tolerate some voltage drop, since the bigger Powerbooks use the same charger. Said and done I dug up an old USB-C adapter that outputs 20V when plugged in. Seemingly these items were quite blurry at the time of taking the picture, hrm.

I then chopped the cable off, stripped it back and twisted the wires together for a quick test to see if it would even work. And it turns out, it did!

Cool stuff! It being a little fall-y-apart-y and delicate, I sat down on the floor (obviously) and pulled out the tiny soldering iron because I was lazy, soldered it all up and added some heat shrink.
