Disclosed are an Internet device and an automatic switching method, apparatus and circuit for a charging interface thereof. The device includes a device-charging interface (20), a base-charging interface (30), a base-charging circuit (40) and a charging-interface automatic switching apparatus (10). The method comprises the following steps: when an external power supply is connected to the device (S001), judging whether or not the base-charging interface of the device is in place (S002); if the judgment result is positive, isolating the device-charging interface of the device, and at the same time switching on the charging circuit via the base-charging interface of the device (S003); if the judgment result is negative, isolating the base-charging circuit of the device, and at the same time switching on the charging circuit of the device via the device-charging interface of the device (S004). The device is easy to implement, reliable in performance, low in cost. |
