WEARABLE DEVICE AND CONTROL METHOD OF WEARABLE DEVICE

A wearable device includes: a wristband, including a first section of wristband with a first interface and a second section of wristband with a second interface; and a main body on the wristband and electrically coupled to the first interface and the second interface, wherein, when the first interface is coupled to a power supply and the second interface is not coupled to a first terminal device, the main body is charged through the power supply. By providing two interfaces on the wristband, in a state in which one interface is connected to the power supply, and the other interface is not connected to the terminal device, self-charging can be realized without a dedicated charging base, and charging is more convenient.
