Here's a brief explanation of the components you mentioned:

5V: This indicates the voltage at which the wireless power supply operates. In this case, it operates at 5 volts, which is a common voltage for USB charging.

2A: This represents the current rating of the wireless power supply. It can deliver up to 2 amperes of current to the receiving device. This is also a common current rating for many smartphone chargers.

Wireless Power Supply: This is the device or module that provides power wirelessly to charge compatible devices. It typically includes a coil that generates an electromagnetic field to transfer power.

Transmitter: The transmitter is the part of the wireless charging system that sends power to the receiver. It generates the electromagnetic field used for wireless power transfer.

Receiver: The receiver is the part of the wireless charging system that captures and converts the electromagnetic energy from the transmitter into electrical energy to charge the device.

Charging Coil Module: This is likely the coil or coils used in the transmitter and receiver for wireless power transfer. Coils are essential components in wireless charging systems, as they facilitate the transfer of energy through electromagnetic induction.
