Abstract:
1. A power bank circuit, comprising: a charger circuit for generating a charging current; a battery circuit coupled to the charger circuit, for receiving the charging current so as to charge a battery included therein and providing a battery voltage; a power conversion circuit for converting the battery voltage to an output voltage and providing an output current; a temperature detecting circuit for detecting a temperature of a packaged structure and generating a temperature detecting signal accordingly; and a current distribution circuit coupled to the temperature detecting circuit, the charger circuit and the power conversion circuit, for adaptively adjusting the output current and/or the charging current in response to the temperature detecting signal; wherein when the temperature indicated by the temperature detecting signal exceeds a first predetermined temperature, the current distribution circuit reduces the output current; when the temperature indicated by the temperature detecting signal exceeds a second predetermined temperature, the current distribution circuit reduces the charging current; wherein the second predetermined temperature is higher than the first predetermined temperature.
