1. A portable electronic device comprising:
- a main body including a plurality of keys exposed on a top side of the main body; and
a display case attached to the main body and including a display, the display case movable between a closed position in which the display case overlies the main body and an open position in which the display case is angled away from the main body;
a first inductive coil disposed within the main body underneath a first region of a top side of the main body positioned laterally away from the plurality of keys, the first inductive coil configured to provide inductive power to, or receive inductive power from, an external electronic device through the first region of the top side of the main body; and
a battery electrically coupled to the first inductive coil.

Abstract
An electronic device and methods for inductively charging an electronic device using another external electronic device. The electronic device may include an enclosure, a battery positioned within the enclosure, and an inductive coil coupled to the battery. The inductive coil may have two or more operational modes, including a power receiving operational mode for wirelessly receiving power and a power transmitting operational mode for wirelessly transmitting power. The electronic device may also have a controller coupled to the inductive coil for selecting one of the operational modes.
