Qi Charging Stand with Wired Devices Charging Support

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.
