Abstract
A wireless charging device for use in providing electrical power to one or more portable electronic devices is provided. The wireless charging device includes a transmission coil coupled to an electrical power source. The transmission coil selectively transmits power from the electrical power source to at least one receiving coil in a first portable electronic device of the one or more portable electronic devices. The wireless charging device also includes a positioning system coupled to the transmission coil. The positioning system is configured to selectively rotate said transmission coil about a first axis and about a second axis.
