The EU is enforcing USB-C on portable devices

<< < (93/111) > >>

AFAIK it's permitted under USB-PD to support only a limited voltage range.

You could have a laptop that refuses to charge from a 5V source -- I've tried it with my Lenovo laptop and it doesn't even bother lighting up the charging LED.

I do question 240W through a Type C connector though.  My work laptop has a 300W brick, and it's a low end gaming laptop (not used for gaming: just happens to be rather good for FPGA work, too, with an 8-core Ryzen CPU.)  So presumably one workaround would be to simply require a 300W+ adapter to be supported some other way.

Well, the EU might want to limit the maximum power of computers anyway, like they did for example with vacuum cleaners.

So, in the eyes of the EU, it might be a good thing that USB-PD can only go up to 240 Watts (for now).

Apple only came up with its proprietary charger identification back when the USB standards didn’t have any charger signaling whatsoever. This affected everyone: since the USB standard didn’t have charger identification at the time, everyone came up with their own thing. Not just Apple. Once the USB standards included charger identification (USB BC, in 2010), Apple made its devices compatible with that. All of Apple’s USB-C products* use bog-standard USB PD.

In other words: you’re whining about something that ceased being a thing over 10 years ago.


*With one exception: the 12” MacBook. It uses a weird voltage. But it’s not because Apple was dumb: USB-PD was not finalized at that point, and Apple followed the preliminary standard. Unfortunately, after Apple released it, the final PD standard changed the voltages, no longer including the one Apple was using. In other words: ALL Apple USB-C devices follow the latest PD standard at the time of release.

I guess the problem is related to Apple devices that don't have USB-C... 8)

Damn. Looks like that's gone the way of the rest of the economy too.
