@EUCommission USB-PD spec is so extremely bloated and complicated that it's difficult to get right; dodgy Chinese companies that already cut corners will make many more mistakes with this.
USB-C can power anything up to 48v DC on such tiny, thin connector pins, spaced so closely together. Arcing is quite common.
And it's just a mechanically unsound connector. Putting data/video on the same cable as power is also quite daft IMO.
We can't have a better, because USB-C is mandatory. Totally daft.
