Abstract
In various embodiments, an electronic device such as a portable computer has a structure that extends from the device to wirelessly transfer electrical power between itself and an external device. The structure may be placed in a non-extended position when not being used for such power transfer. In some embodiments power transfer may take place in either direction, and may be used for various purposes, such as to provide operational power and/or to charge a battery. The external device may be placed on or near the extended structure for power transfer to take place.
