Wireless charging technology facilitates the transmission of electrical energy from a power source to an electrical load without connecting wires.
Qi is an interface standard developed by the Wireless Power Consortium for inductive electrical power transfer over distances of up to 4 cm (1.6 inches).
The Qi system comprises a power transmission pad and a compatible receiver in a portable device.
To use the system, the mobile device is placed on top of the power transmission pad, which charges it via electromagnetic induction.
