How does the Audi A5 Wireless Charging Pad work?

I've heard that the Audi A5 has a wireless charging pad option. How does it work and which devices are compatible?

The Audi A5 wireless charging pad uses Qi technology to charge compatible devices. Simply place your phone on the charging pad and it will start charging. You can also use a Qi adaptor for non-compatible devices.

The Qi charging pad in the Audi A5 uses electromagnetic induction technology to transfer power to your device. This makes it more efficient and safer than traditional wired charging methods.
