It sounds like they're trying to standardize the actual chargers, I wonder how that will work USB-PDs many different modes? What about proprietary fast charging schemes? (maybe those already died out after the move to USB-c?).
I'm slightly uncomfortable with the idea of a universal standard stifling innovation, so hopefully the EU will be responsive if something better gets invented in the future. I'm guessing that whatever comes after USB-C will exist in the US and Asia for years before its allowed in the EU... which may or may not be a good thing I suppose. USB-C as a plug has so many capabilities.
It's interesting that they're looking at wireless charging too. Other than my toothbrush and an induction stove, I can't remember the last time I saw wireless charging that wasn't Qi. The only exception is some of the experimental room-scale charging startups. I suppose they're already fighting against the laws of physics, the laws of the EU can't be that much worse.
