Best Wireless Smartphone Chargers

Wireless charging involves the concept of magnetic resonant coupling. It is the ability to transmit electricity through the air by creating a magnetic field between two circuits, a transmitter and a receiver. Eventhough wireless technology was existed before but there were not many practical applications. But once Apple iPhone company started including it in devices such as new iPhone line, this concept became popular. currently there are more than half dozen wireless charging technologies in use. Wireless charging is getting popular in various fields like healthcare, automotive and manufacturing industries. The popular wireless charging technology now in use count on an eletromagnetic field(EMF) between two copper coils, which limits the distance between a device and the charging pad.

Basically there are three types of wireless charging

Charging pads: Use tightly-coupled electromagnetic inductive or non-radiative charging

Charging bowls or through-surface type charger: Use loosely-coupled or radiative electromagnetic resonant charging that can transmit a charge a few centimeters.

Uncoupled radio frequency(RF) wireless charging: Allows a trickle charging capability at distances of many feet.

Both tightly-coupled inductive and loosely-coupled resonant charging works on the same principle that is, a time-varying magnetic field induces a current in a closed loop of wire.
