An apparatus and method for providing a selectively reduced voltage to a portable electronic device are disclosed. When a determination is made that an output voltage from a voltage source exceeds a predefined maximum permitted voltage, a plurality of circuitries, including an adaptive active current limiting circuitry, are enabled in order to derive the reduced voltage from the output voltage. The reduced voltage is at least at or below the predefined maximum permitted voltage and is supplied to the portable electronic device by battery circuitry that includes the active current limiting circuitry.
