ABSTRACT:
A contactless, inductive charger having a generally planar surface is provided. An image, text or other visual indicator is disposed upon the substantially planar surface such that the visual indicator represents a preferred placement orientation for an electronic device for optimal inductive charging. The charger includes a primary coil positioned within the boundaries of the image, such that a user has a visual guide for placing the device on the charging surface for maximum efficiency in charging. The visual indicator, which may be a picture, outline, text or other directional indicator, may be geometrically similar to a shape of the electronic device or may be in the shape of a generic device. It may be disposed upon the charger by a method selected from the group consisting of painting, molding, silk screening, plating, vapor deposition and adhesive retention.
