Function
wireless charging technology, it is also known as inductive charging, rely on the inductance between the coils.
the current through the coil that produces magnetic resonance, and then through the coil converted into current.
The device produces the magnetic field which is hot sending terminal, and the other 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 have to buy a wireless receiver for matching the use.
