Charger: Supplies up to 240 W under the USB PD 3.1 standard, serving as the power source of the fast-charging system.
CC communication line: Carries USB PD protocol messages for bidirectional handshaking and intelligent power negotiation between devices.
E-Marker chip: Stores cable capability and identification information so the system can identify a suitable cable for 240 W operation.
VBUS power conductors: Use appropriately sized, low-resistance conductors to carry up to 5 A reliably.
