A Wireless Power Receiver Bridge working as a 7.5W Qi Charging Stand or as an USB Type-A Power Port

This AirFuel Resonant Power Receiver Bridge receives resonant power from any jjPlus 10W or above power transmitters to provide power to the Qi transmitter and USB type-A connector on the charging stand.  When a Qi compatible phone is charged on the stand, 1. spatial freedom is enabled and 2. user can still operate the phone while charging.  The USB-Type A connector at the back provide support to wired-charging of legacy phones and devices.
