1. A pinless power plug for receiving wireless power from a pinless power jack, the pinless power plug comprising:
at least one secondary coil for inductively coupling with a primary coil, wherein the primary coil is associated with the pinless power jack, and wherein the primary coil is shielded behind an insulating layer;
an annular magnetic anchor arranged around a perimeter of the at least one secondary coil concentric and non-overlapping with the at least one secondary coil, wherein the annular magnetic anchor is configured to magnetically couple with an annular magnetic snag in the pinless power jack; and
at least one magnet spaced away from and outside of the annular magnetic anchor, wherein the at least one magnet is configured to magnetically couple with a magnet in the pinless power jack at a particular orientation or angle.
