the problem that ^can^ occur is drawing overcurrent. usbc is supposed to support higher power demands, and if your usb port cant pass the current because its made of components too fine/resistive for the current being drawn, then {P@FF!}

PD hosts are required to monitor and limit current draw. Any magic smoke released is the fault of the host device, not the peripheral that tried to draw too much current.

thats what i mean, and when they dont limit current draw because despite being required to the design is cheaper faster not better, then thats it. you get heat at the highest resistance so port gets very hot and undervoltage beyond that resistance, so device gets wonky, unless it is regulated, to prop up the voltage

That's not how it works (ohm's law for firsts)
