I combined one of those cheap breakouts with this variable voltage power supply - https://www.amazon.com/gp/product/B0861LGM15 - and a 3d printed enclosure to make a benchtop power supply pretty affordably. Just use your laptop's power supply and now you can have any voltage and limited amperage.

I am waiting for an updated version that does PD 3.1, so it can go to 48V/5A.
That's 240W. You could charge an e-Bike via USB-C with that. Insane.
Yep. That's exactly what I am looking for. Use USB-PD to charge small electric vehicles in a standardised way ;) See https://jan.wildeboer.net/2024/06/Charging-SEVs-A-Modest-Pro... where I describe the concept and https://github.com/manuelbl/usb-pd-arduino/wiki where there is Open Source code (and schematics) to do PD sniffing and sink negotiation.
