    摘要: An electronic device is provided. The electronic device includes a connector including multiple conductive terminals, a battery, and a power control circuit electrically connected to the connector and the battery, wherein the power control circuit controls a value corresponding to electrical information on a first conductive terminal among the multiple conductive terminals so that a first time interval during which a first value is maintained and a second time interval during which a second value is maintained after the first time interval are alternated for each time interval among the multiple time intervals, identify, in response to the connection of the electronic device to the external device through the cable connected to the connector, whether a size of a time, during which the value is maintained as one of the first value or the second value, is smaller than a designated value, and select a first method.

    摘要: Multiport adapters include a power connection port, a host connection port, a peripheral device connection port, a controller, and a power supply circuit. The controller is configured to receive, through the power connection port, first power information regarding power suppliable from a power supply device to the multiport adapter, determine a maximum power value in the first power information, transmit a message requesting the power supply device to supply power of the maximum power value to the multiport adapter, determine a third power value obtained by subtracting, from the maximum power value, a first power value consumed by the multiport adapter and a second power value set to be supplied to a peripheral device, generate, based on the third power value, second power information regarding power suppliable from the multiport adapter to a host device, and transmit the second power information to the host device through the host connection port.
