Wireless charging also known as Inductive charging which consists two coils one is a transmitter coil another one is receiver coil. In present scenario existing communication network uses wireless nodes or devices for feasible and reliable communication. Charging these wireless devices the authors have prepared a review paper based on wireless charging. Wireless charging is a process which uses ElectroMagnetic (E.M.) field to transfer energy between wireless nodes and which is usually done with a charging station. This paper carries several research papers related to wireless charging field.
