Abstract

A unit for transferring power in an inductive manner to at least one power-receiving device, and a system comprising such a unit and such a device. The unit includes at least one coil structure configured to allow various degrees of translational and rotational freedom of movement of the power-receiving device relative thereto. This provides increased ease of use, since it is not necessary for a user to place the power-receiving device in mechanical or other registration with the unit.
