Wireless power transfer system charging multiple devices, through inductive coupling method which is classified under near field transfer region. In this project, we intend to achieve wireless power transfer charging multiple devices such as mobile phone, toothbrush and other low end power devices without the use of conventional copper wire or cable between the transmitter module and receiver module. In this paper, result analysis was taken for voltage and distance of separation of coil of each receiving end device to know the efficiency of power transfer and graph are illustrated to show the comparison of voltage and distance of separation of coil of LED, DC fan, and mobile phone, digital camera, toothbrush.

Keywords : Wireless power transfer charging multiple devices, transmitter module, receiver module, mobile phone.
