Abstract
Input devices and methods for charging input devices are disclosed. A stylus input device has a tip configured to interact with a touch computing device and a body connected to the tip. The stylus has a nozzle housing between its body and tip, electrical components, and an internal rechargeable power source. The internal power source can store power received via a connection between an external power source and a conductive surface on the nozzle housing and supply power to the stylus'"'"' electrical components. A method for charging a stylus determines whether power is being received via an electrical connection between a conductive surface on a nozzle of the stylus and an external power source and then determines an amount of power stored in the stylus'"'"' battery. If the stylus is receiving power from the external power source and the battery is not fully charged, the method charges the rechargeable battery.
