Very nice post. I'll add that there was a recent addition to the USB-PD and USB-C spec to allow power up to 240 watts. That's up to 48 volts at up to 5 amps. This is backwards compatible. Any new cable rated for 5 amps is to also be rated for 48 volts, though I expect many manufacturers wanting to compete on price will follow the old spec. Or not bother trying to comply at all. Buyer beware.
