Abstract

A mobile communication device includes a battery controller and an inductive charger. The battery control is adapted for electrically connecting to a rechargeable battery of the portable electronic device. The inductive charger includes a power connector adapted for electrically connecting with a power source, and a transmitting inductor electrically coupling with the power connector for generating an electromagnetic induction, wherein the receiving inductor is electrically inducted to the transmitting inductor in a contact free manner for wirelessly transmitting an inductive charging power to the rechargeable battery of the portable electronic device through the transmitting inductor. Therefore, when the rechargeable battery of the portable electronic device is located within an induction distance of the inductive charger, the rechargeable battery of the portable electronic device is automatically charged.
