Right, but if it's not actually USB-C, at best you're looking at the device not working when plugged into a proper USB-C power supply. At worst you're facing fried electronics.

Agreed that would be like wiring a standard North American household wall outlet with 240VAC. Technically possible, but will probably fry anything not expecting it.

I came across a group of racks in the IT room in a (US) factory once that had 208v on their standard NEMA 5-15R sockets.

Their global-market IT stuff didn't care at all. But some of the US-market audio stuff I was integrating came with old-school linear power supplies, and those items cared a great deal.

Have run into that exact thing also, not that the sockets were 5-15R but IEC C13 in a rack CDU. But someone had some adapter pigtails from C14 to a standard NEMA socket, of course that doesn't change the voltage at all. Hilarity ensued.
