A car audio apparatus for charging plural mobile terminals is provided to supply a power to the mobile terminals by dividing a power inputted to a car audio into several voltage to be used as a power of the mobile terminals. A power port(10) has plural terminals to be used as at least one power source of a mobile terminal. A voltage division circuit(20) divides the voltage inputted from a power source of a car audio into at least one voltage and allocates the divided voltage to the terminal of the power port. A power port detecting circuit(30) detects whether the mobile terminal is connected to the power port, and switches on and off the voltage division circuit according to the detected result.
