Abstract
An inductive charging system including an inductive charger having an inductive charging surface and an alignment feature depicted on a surface of the inductive charger indicating a location of the inductive charging surface. A structural feature may extend substantially perpendicular to the alignment feature and provides a guide for positioning of a portable device to facilitate inductive changing of the portable device by the inductive charging surface. The inductive charger may include a plurality of inductive chargers positioned to facilitate charging of a portable device by two or more of the plurality of the inductive chargers.
