An inductive power transfer system, for providing power to an electric load without the use of connecting wires. The system includes an inductive power outlet having a primary inductor and an inductive power receiver having a secondary inductor. In various embodiments, the power transfer system may also incorporate (i) a signal transfer system, for passing data signals between the receiver and the outlet, (ii) an alignment mechanism, for facilitating the alignment of the secondary inductor to the primary inductor, (iii) a heat dissipation system for cooling the receiver so that it may be handled by a user, and (iv) a magnetic flux guide for guiding magnetic flux from the primary inductor to the secondary inductor.
