The invention discloses a power receiving device and a power supply device for charging. The power receiving device comprises an internal charging member, a control member and a gating member, wherein the gating member is connected to the power supply device via a control line (ID) and a power supply line (Vbus), and respectively outputs first charging current and second charging current to a positive electrode of a chargeable power source and the internal charging member. When the charging receiving device is connected with a power supply including an external charging member, the gating member is connected with the output end of the first charging current via the power supply lien (Vbus). The control member starts the external charging member to supply power via the control line (ID). According to technical schemes provided by the invention, the heating amount of the charging member in the power receiving device is reduced when a relatively heavy current is used for charging, and the terminal stability as well as user experience of a terminal is ensured.
