1. A wireless power receiver apparatus, comprising:

  • a coil configured to wirelessly receive power via a magnetic field generated by a transmitter, the wirelessly received power at a level sufficient for powering or charging a load; and

    a housing comprising;

    a first volume configured to house the coil; and

    a second volume different than the first volume and configured to house electronic components, a level of the magnetic field within the second volume being less than the level of the magnetic field within the first volume, the second volume bound by;

    a horizontal shielding member along a first portion of the second volume, the horizontal shielding member defining a horizontal shielding member plane substantially parallel to a plane defined by the coil, anda vertical shielding member along a second portion of the second volume, the vertical shielding member defining a vertical shielding member plane substantially orthogonal to the plane defined by the coil,wherein the horizontal and vertical shielding members are configured to reduce the level of the magnetic field between the first volume and the second volume.
