摘要： A charging device includes a battery charger, a first rechargeable battery, a first connector, a boosting circuit, a switching circuit and a first controller. The first rechargeable battery is electrically connected to the battery charger, the first connector is adapted for connecting the electronic device, and the electronic device includes a second rechargeable battery. The first controller is electrically connected to the switching circuit, and the first controller determines whether a difference by subtracting a voltage of the second rechargeable battery from a voltage of the first rechargeable battery is higher than a predetermined potential difference. When the difference is higher than the predetermined potential difference, the first controller controls the switching circuit to electrically connect the first rechargeable battery with the first connector, so that the first rechargeable battery and the first connector are electrically isolated from the boosting circuit.

摘要： A wearable device includes a main body, a detection module and a controller. The detection module is located on the main body and includes an upper casing, an opposite lower casing and a proximity sensor. The lower casing has an elastic material. The proximity sensor is located on the upper casing to measure a distance from the proximity sensor to the elastic material. The controller is electrically connected to the detection module. The elastic material has a contact surface for the user to contact when the wearable device is worn on the user, thereby switching between an active mode and a standby mode of the wearable device. In addition, the present disclosure further includes an earbud.
