Sorry i’m very bad at understanding how power work but maybe the link and the documentation can answer your question ?
Comment on The EU common charger : USB-C

Is it only the physical connector or also the Power Delivery protocol? Because if it’s only the connector you might end up plugging 2 things that are not compatible with each other.

I read the website but it doesn’t say. But it does say that the consumer will have to check that the charger is compatible with the device so you might end up frying your devic6if you connect them to the wrong USB C Charger (things that were prevented because of the different connectors). I don’t say that the directive is wrong but it doesn’t go far enough. It should force all devices manufacturers and chargers manufacturers to use the power delivery protocol so consumers don’t have to worry about power compatibility between chargers and devices.

No device that is properly following the USB standard will be fried by, or fry, another USB device.
It’s true that a USB-C cable might not work with some PD requirements and will support only a certain USB data version or lower, but all of USB is backwards compatible, you will get slower speeds or less power but not anything dangerous.
Unless the device(s) you use are not properly following the USB standards

As others mentioned in the thread, Nintendo Switches clearly don’t follow the standards. So having this hole patched in the legislation would be nice.

That might be what some document says, but it’s definitely NOT true in the real world. Benson Leung (no longer active) proved that by meticulously testing chargers from many manufacturers (some of the popular ones too).

Oh…something it telling me it won’t end well. I was full of hope after all those bad new on politic and climate change. I really hope they anticipated it. 😔

The law requires a the industry agree to a “common” charger. Right now, the industry has picked USB but that might change.
It’s up to the industry to figure out technical details…
But basically it needs to be possible to buy one charger, from any brand, that will “work” to charge any device. That doesn’t necessarily mean it will work well… a 5w charger might take 20 hours to charge a full size laptop battery for example… And that’s if the laptop is off. Some USB chargers provide 240w… you probably don’t want one of those for regular use though - they will be big and heavy and expensive.
