12 Do I need a USB connection for wireless charging?
The answer is yes. Even though the wireless charger does not need to be connected to the phone, as an electronic device, it needs to be plugged into the power supply for wireless charging function. Typically, wireless chargers need to be plugged into a power adapter, and the power adapter needs to be connected to a USB plug into a socket or a device such as a computer. Therefore, if you want to use a wireless charger, you also need to connect some form of USB plug.
