    Abstract: Apparatuses and systems are provided for improving wireless power transmission for mobile devices. An enclosure for a mobile device may include 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 a mobile device. A distance between the receiver coil and the transmitter coil may exceed a range over which the transmitter coil may be able to transfer power to the receiver coil via a single wireless coupling between the transmitter coil and the receiver coil. The first wireless coupling, the second wireless coupling, and the third wireless coupling, when established, may enable the transmitter coil to perform a wireless power transfer to the receiver coil.
