Abstract
An electronic device includes an input power detection unit, a transmission control unit and a converter. The input power detection unit is configured to determine an input voltage value and an input current value of an input power. In response to the input power, the transmission control unit is configured to determine a first voltage value and a first current value associated with another electronic device via a handshake process. The voltage converter is configured to convert the input power into a first power required by the another electronic device.
