Abstract
Disclosed are systems, apparatus and devices for wireless charging of electronic devices that include magnets in close proximity to primary and secondary inductive charging coils to move the coils within close proximity and within axial alignment to one another. The system includes a charging apparatus including a first coil having within close proximity a first magnet, the primary coil and magnet together capable of moving within the charging apparatus in accordance with magnetic attraction. A battery charging device includes a secondary coil having within close proximity a second magnet. The magnets can attract so that the coils are moved close together. In this way the respective coils are coupled so that inductive charging may be provided. An engagement structure of the charging apparatus can help to maintain the first coil in a particular orientation within the charging apparatus so that the alignment of the coils is optimized.
