Zusammenfassung:Apparatus and methods directed to wireless power are disclosed. A charging device includes an antenna circuit for wirelessly receiving power from a first device via a power antenna. Received power can be stored in an energy storage device. The antenna circuit can wirelessly power or charge a plurality of second electronic devices via the power antenna based on power stored in the energy storage device. Furthermore, a wireless charging apparatus is disclosed that includes a display for receiving a device placed on its surface. Changes in a magnetic field in response to the placement of the chargeable electronic device on the surface of the display is detected. A communication link with the chargeable electronic device in response to the change in the level of the magnetic field is activated. A transmit antenna circuit wirelessly transmits power to the chargeable electronic device.
