| 1. A portable electrical or electronic device adapted to receive power from a primary unit that has a power transfer surface
and an inductive power supply which supplies power inductively,
said device being separable from the primary unit and having an inductive power receiver adapted to receive power from the
inductive power supply by inductive coupling when the device is placed on or in proximity to the power transfer surface,
the device being arranged such that the device can be placed in any position along a line extending in one translational dimension
across the power transfer surface to receive power inductively from the inductive power supply,
and wherein the device comprises at least one attaching element comprising suckers, or a self-adhesive or rubbery surface,
disposed on the power transfer surface which temporarily releasably attaches the device to the primary unit in any said position
along said line such that the device is held on or in proximity to the power transfer surface,
said attaching element(s) providing a non-gravitational force, acting to resist movement of the device away from the power
transfer surface in a direction substantially orthogonal to that surface, when the device is attached to the primary unit
in any said position along said line.
