I was testing a mini module (CKCS U1E 65w) for USB charging from a DC source to many USB C protocols.

I've noticed with "vooc" charge at 9v 3.3A the inductor's module is at 90°c
A bit high moreover if it has an enclosure as this one:

With this refurbished adhesive heat sink it falls at 60°c

Since the #powersupply for my #IBM #ThinkPad 755C doesn't work reliably and uses a very strange connector, I unsoldered the socket from the internal board. It came on a handy mini #PCB, which I reengineered in @kicad for a barrel jack. It also has connections for a 20V USB-C PD trigger board that I had lying around.
The boards were manufactured by @aislerhq and fit perfectly. Only the barrel jack was a bit tight since I had to smallen the holes a bit to place it on the board.
Now I just have to decide which to solder back into the #laptop. Will have to try which fits better inside the hole.
