Brief Introduction:
Wireless charging technology, it is also known as inductive charging, relying on the induction between the coils.
The current through the coil which produces magnetic resonance, and then through the coil converted into current. 
The device produces the magnetic field which is called transmitting terminal, and the another device converts current which is called receiving end. 
So as long as your phone has the built-in receiver, wireless transmission can be achieved. If not, you should buy a wireless receiver for matching the usage.
