However, although it is becoming more and more popular, there are still some problems behind it. There are many reasons why wireless charging should not be used now: it has some limitations, it is not efficient and it has some bad influences. Wireless Charging which can be called inductive charging uses electromagnetic fields to transfer energy between two unconnected objects. It was invented by scientists from MIT. They transferred 60 watts with ~40% efficiency over two meters, which was able to light up a bulb(Kurs 83).
