Abstract

A charging device including a battery; a first induction coil coupled to the battery; and an induction core extending through the first induction coil. The induction core has a portion which extends in an outward direction from the charging device and is adapted to removably couple with a second induction coil of a portable electronic device by extending into the second induction coil.

Description

technical field [0001] The present invention relates to a charging system, and more particularly, the present invention relates to a charging system for a portable electronic device. Background technique [0002] The use of battery powered portable electronic devices such as mobile phones, personal digital assistants (PDAs), MP3 players, etc. is increasing. Problems associated with battery discharge in portable electronic devices are therefore also on the rise. Likewise, there is an increasing need to recharge batteries in portable electronic devices while away from home or office. Battery charging docks that utilize induction to charge batteries in portable electronic devices are known in the art, such as those sold by Splashpower Ltd. and MobileWise Inc. However, these types of battery charging trays must be connected directly to an electrical outlet or mains and have a relatively large footprint. The pads can be difficult to carry, and not all portable electronic devic...
