Abstract:
1. A cable for charging a device, comprising: a first connector to connect to a universal serial bus (USB) port of a host device or a power adapter coupled to a power outlet, the first connector comprising a plurality of pins, where a first pin is to receive power from the USB port of the host device or the power adapter; a charging enabler coupled to the first connector, the charging enabler comprising at least one transistor coupled to the first pin of the first connector, where the charging enabler is to enable charging of the device based on a voltage applied between the first pin of the first connector and a data pin of the first connector; and a second connector coupled to the charging enabler and to provide power to the device via the charging enabler, where the charging enabler further comprises: where one of the at least one transistor is coupled to the first and second resistors, the charging enabler being to provide a first charging current to the device when the first connector receives power from the power adapter.
