An adaptive power converter (110) of a mobile charger (102; 902) includes a power converting circuit (211) for converting a source voltage signal (Vs) and a source current signal (Is) into a DC voltage signal (Vdc) and a DC current signal (Idc); a communication interface (213) for transmitting a data signal (DATA) and outputting the DC voltage signal (Vdc) and the DC current signal (Idc) to a charging cable (130); and a charger-side control circuit (219) for receiving the data signal (DATA) and controlling the power converting circuit (211). The charger-side control circuit (219) controls the power converting circuit (211) to adjust the magnitude of the DC current signal (Idc) or the DC voltage signal (Vdc) based on the data signal (DATA) transmitted from a mobile device (104) so as to control a voltage drop of the charging cable (130) to be less than a predetermined threshold.
