Abstract
Disclosed is a method for a USB power receiving device selecting a power supply option. The method is performed by the USB power receiving device and includes: receiving N power data object(s) (PDO(s)) from a USB power supplying device, in which the N is a positive integer; checking whether at least one of M PDO(s) of the USB power receiving device matches at least one of the N PDO(s) according to a selection rule including a voltage requirement and a current-related requirement and accordingly generating a request data object (RDO), in which the M is a positive integer; and transmitting the RDO to the USB power supplying device to request the USB power supplying device to supply power to the USB power receiving device according to the RDO.
