Abstract:
An inductive power transmitter device (1) for inductively providing power to a mobile device provided with a receiver coil unit is disclosed. The transmitter device comprises a holder (3) and a coil arrangement (11). The holder (3) has a cavity (5) defined by two walls (7a,7b) providing facing surfaces (9a,9b), wherein the cavity is configured for receiving the mobile device between these facing surfaces. The coil arrangement (11) has two transmitter coil units (13a, 13b), wherein one of these coil units is arranged into one of said walls and the other of these transmitter coil units is arranged into the other of said walls, and wherein each of the coil units is configured for inductively coupling to the receiver coil unit of the mobile device when inserted into the cavity of the holder. These features allow a user to connect the mobile device to the transmitter device without being worried about the right position of the mobile device.
