1. An apparatus for charging a battery, the apparatus comprising:
a first power transfer coupling arranged to selectively couple to the battery to charge the battery, wherein the first power transfer coupling comprises a socket electrically coupled to the battery; and
a second power transfer coupling arranged to selectively couple to the battery to charge the battery, wherein the second power transfer coupling comprises a pickup pad electrically coupled to the battery, wherein power is transferred to the pickup pad from a charging pad by inductive power transfer;
wherein the first power transfer coupling is selected in response to a cable being plugged into the socket where the cable is connected to an electrical supply, and wherein the pickup pad comprises:
one or more ferromagnetic slabs in a first layer;
a coil having at least one turn of a conductor, the coil being arranged in a second layer substantially parallel to that of said ferromagnetic slabs; and
a shield member comprising a backplate defining a third layer, said backplate arranged to control said magnetic field generated by said coil.
