Apple fast charge protocol

Despite Apple using USB ports in power adapters at the beginning they are using the proprietary protocol APPLE 2.4A and it's out of USB standard.

However, since 18W charger (A1695), Apple chargers use universal USB PD charging protocol and can charge 3d party devices as well as Apple devices can be charged from 3d party USB PD chargers.

The most powerful adapter Apple sells for iPhones is 20W, more powerful versions are designed to be used with iPads and laptops. However, Apple PD charges can charge laptops, iPads, and iPhones.
