1. A method for charging a power receiver device by a power source device comprising:
supplying a first voltage from the power source device to the power receiver device;
receiving feedback, at the power source device from the power receiver device, regarding the first voltage, the feedback comprising a required voltage at the power receiver device;
computing, based on the feedback, a difference between the required voltage and the first voltage; and
adjusting the first voltage based on the computed difference by adjusting an output voltage of a buck-boost regulator of the power source device.
