How wireless Chargers work

Wireless Charging provides a convenient, safe, and reliable way to charge and power millions of electrical devices at home, in the workplace and in industry.

By eliminating the use of physical connectors and cables, wireless charging provides a number of efficiency, cost and safety advantages over the traditional charging cable.

From smartphones, to hand-held industrial devices and heavy-duty equipment applications, wireless power maintains safe, continuous, and reliable transfer of power to ensure all varieties of devices and equipment are charged and ready to go at a moment’s notice.


Essentially wireless charging (a.k.a wireless power transfer or charging by induction) uses electromagnetic fields to safely transfer power from a transmitting source to a receiving device for the purposes of wirelessly charging (or recharging) a battery.  As the name suggests, it does so without the use of a physical connection.


Wireless charging is based on the principle of magnetic resonance, or Inductive Power Transfer (IPT).  This is the process of transferring an electrical current between two objects through the use of coils to induce an electromagnetic field.

The diagram below simplifies the process of wireless charging and power transfer into 5 key steps.
