Abstract: An accessory device, and an electronic system and an operation method thereof are provided. The accessory device includes a functional module, a first connection interface, a second connection interface, a switch module, and a microcontroller. The first connection interface is configured to be coupled to an external first electronic device. The second connection interface is configured to be coupled to an external second electronic device. The switch module is disposed between the first connection interface and the second connection interface, and between the first connection interface and the functional module. The microcontroller controls the switch module, so that at least one of the first electronic device, the second electronic device, and the functional module supplies power to at least another one of the first electronic device, the second electronic device, and the functional module.
