Abstract
An example inductive charging system includes a housing including a first wall and a second wall opposite the first wall. The first and second walls at least partially form a channel extending along an external length of the housing. The system also includes an inductive charging coil disposed within the housing. The charging coil includes a substantially annular central axis and a wire wrapped in a spiral configuration circumferentially around the central axis. The charging coil includes a first end disposed proximate the first wall, and a second end substantially facing the first end and disposed proximate the second wall. The charging coil is positioned such that the channel passes through a gap extending from the first end to the second end.
