Wireless charging is a technology that allows devices to charge their batteries without the need for physical cables. It uses electromagnetic fields to transfer energy between a charging pad and a compatible device, such as a smartphone or smartwatch. This process is often referred to as inductive charging. To use wireless charging, you simply place your device on a charging pad that is connected to a power source. The pad generates an electromagnetic field, which the device converts back into electrical energy to charge its battery. This method offers convenience and reduces wear on charging ports.
