NOTE:
Wireless charging = transmitter + receiver (both can be charged together)
1: There is a "charger" (ie coil patch): If your phone has a built-in "receiver", or you have already purchased a "receiver" in another home, then you only need to buy a "transmitter"Charging.
2: There is a "generator" (ie the base): If you have already purchased the "transmitter", then you can just recharge by purchasing the "receiver".
