How does wireless Qi charging work?

Qi Wireless Charging uses a resonant inductive coupling between the sender (the charging station) and the reciever (the mobile device). A regular test signal is sent by the sender to check for a capacity or resonance change, telling the Qi enabled charger base that a qi compatible phone is present.

What is Qi standard for wireless charging?

Qi (pronounced “chee”) is the world’s de facto wireless charging standard for providing 5-15 watts of power to small personal electronics. Though it is primarily used to charge smartphones, the standard can also apply and easily be used to provide power for a growing number of consumer devices.
