Abstract: The present invention discloses a high efficiency charging system and a charging circuit therein. The high efficiency charging system includes a power supplier and a power receiver, which are connected via a transmission wire so that power is transmitted from the power supplier to the power receiver. The power receiver includes a voltage conversion circuit and a control circuit. The voltage conversion circuit converts an adjustable input voltage provided by the power supplier to an output voltage and generates an output current for charging a battery. The voltage conversion circuit adaptively adjusts the output current according to a voltage drop between the adjustable input voltage and the output voltage. The control circuit senses the adjustable input voltage and the output voltage and instructs the power supplier to adjust the output voltage according to the voltage drop between the adjustable input voltage and output voltage.
