EU rules on common chargers apply to laptops from today. It means that all new laptops sold in the European Union must now support USB-C charging.
In December 2024, the rules came into force for mobile phones, tablets, digital cameras, headphones, videogame consoles, and portable speakers.
Laptop manufacturers were given a longer lead in time to allow for redesign and transition to the common charging system.
There 100% has to be regulation on charges and ports, maybe a colour system like how usb3 ideally is blue.
They already do that de-facto, I think all my high power usb3 charger ports are orange, regardless of manufacturer. Codifying it into law is probably a good idea
