Power Profile

Power & Charging

The set of voltage and current combinations a USB PD charger or cable supports.

A USB PD charger advertises its power profiles during handshake: for example, 5V/3A, 9V/3A, 15V/3A, 20V/3.25A (65W). The device selects the best match for its battery. Cables also have power profiles determined by their AWG rating and e-marker chip, which may limit available profiles.
