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.

Apple does not produce specialised PD chargers designed only for smartphones or only for laptops; any charger compatible with the PD protocol can charge any Apple device.

A detailed list of Apple devices (smartphones, tablets, laptops) with supported voltages and power ratings via the PD protocol can be found on the USB PD protocol page.
