Today with the advancement of technologies and it is widely used in every community where every person is a user of a mobile phone, laptop, notebook and many other electronic device. These electronics supplied power through wired transmission from power supply and/or plug-in cables. Energy transfer via wires or cables creates mess and unpredictable appearances that can cause to a greater power loss and this lead to wireless power transfer transmission. The transmission of wireless power is currently a well-known subject. When a system is within the range of the transmitter, energy can be transferred. The aim of this project therefore is to understand the concept of the wireless power transfer and to examine other kinds of media or medium which are used for the transmission of power instead of the traditional induction coil method. Traditional induction coil is widely used and still it has its own weaknesses and limitation that cause it hard to be used and also harmful when the greater radiation from the coil. The media or the medium that will be used as the transmitter is the visible light which it can be obtain easily and anywhere or any place. The circuit is designed with the aid of multiple software Proteus, Matlab and Fritzing to ensure the design and it hardware can function properly and accordingly to the simulation from the software during implementation of the hardware. The project hardware is also proved by the use of only some key elements such as photovoltaic cells, transistors, voltage controllers, resistors, diodes etc
