At this point, many of us have gone all-in on USB-C. It’s gotten to the point that when you occasionally run across a gadget that doesn’t support being powered USB-C, the whole experien…
Yeah, 9v at the very least, but 15V would be a useful option too.
I’m also just now realising USB-PD doesn’t spec for 12V which feels like an odd omission

From the article:
Sure, it wouldn’t be much harder to add support the other voltages offered by USB-C Power Delivery, but how often have you really needed 20 volts on a breadboard? Why add extra components and complication for a feature most people would never use?
My friend, you write for hackaday, this is a weird take
Any sort of op-amp circuit would easily make use of a 15V input, or better yet using the full 20V with a 10V reference to get +/-10V voltage rails for an amplifier circuit.
