Wireless power transmission has been commercialized for quite awhile now and since the mobile phone industry is thriving, there is a constant need in charging the mobile phone wirelessly. However, since the wireless charger was recently introduced, it comes with several limitations. One of which is the constant need to change the connections and components of the wireless charger. The changing of connections and components requires a big amount of research and this would incur additional charges to the production of these wireless chargers. Thus, this project aims to solve this problem by making modifications of the transmission coils. Through just modifications of the coil, manufacturers would be able to save a lot of manufacturing cost and this would definitely decrease its market price. So, to rectify this problem, the concept of the inductive wireless charging will be understood. Then, the characteristics of the coils will be understood by changing the parameters of the coils and then testing the charging of the mobile phone by placing the mobile phone on top of the transmission coil. Next, the transmission coils will be connected in series and parallel as well as adding magnetic sheet and tape as the magnetic shielding. The charging of the phone is observed on each of these configurations.
