The Rise of USB-C: How the EU’s New Mandate is Redefining Universal Connectivity

Reduced adapters, unified “quick charging”

The most notable effect this USB-C mandate has imparted thus far pertains to Apple, which, after initial resistance, has progressively transitioned its devices from its exclusive Lightning connector to USB-C. Its most recent iMac includes a Magic Keyboard, Magic Mouse, and Magic Trackpad that all interface through USB-C. The corporation halted the sale of the Lightning-enabled iPhone 14 and iPhone SE in the EU after December 28.

Beyond merely stipulating the presence of a USB-C port, the Directive mandates that any device with “fast charging”—drawing over 5 volts, 3 amperes, or 15 watts—must enable the USB Power Delivery (USB PD) protocol. This should guarantee that they can effectively negotiate charging rates with any USB PD compatible charger instead of relying solely on their own proprietary charging brick or adapter.

In Europe, products must specify on their packaging whether they include a charging plug or a mid-cord brick. An alternate label will denote the minimum and maximum power requirements for charging a device and whether it supports USB PD.

Can the EU ensure harmony among cables and cords?

The EU’s jubilant post on X has been met with skepticism in the form of numerous replies from those doubtful, asserting that designating USB-C as “THE charger” might inhibit companies from innovating other means of power delivery. Most of these concerns are addressed within the actual legislative text, as higher-powered devices are exempt, secondary power plugs are permitted, and wireless charging largely escapes regulation. “What about when USB-D comes along?” is a question no one can genuinely answer, though it appears a tenuous justification to sidestep the discussions around e-waste, fragmentation, and consumer confusion in the overall device charging landscape.

The manner in which the Common Charger Directive will be implemented remains to be seen, as this responsibility is left to the individual member states. It is also uncertain whether companies will adhere to it uniformly across their global product ranges or if they will simply develop specific products compliant with EU regulations.
