Claim 0:
1. An apparatus comprising:
a first electrical coil configured to establish a first wireless coupling with a transmitter coil of a power supply; and
a second electrical coil configured to establish a second wireless coupling with the first electrical coil and to establish a third wireless coupling with a receiver coil of an electronic device, wherein:
the first wireless coupling, the second wireless coupling, and the third wireless coupling, when established, extend a range over which the transmitter coil is capable of performing a wireless power transfer to the receiver coil, and
a number of windings of the first electrical coil and the second electrical coil is an average of a number of windings for the receiver coil and a number of windings for the transmitter coil, wherein the number of windings for the receiver coil is different than the number of windings for the transmitter coil.
