Abstract
A portable battery charger for a portable media player recharges the portable media player without needing to be plugged into a wall or other stationary power source. The portable battery charger also adds extra functionality to the portable media player by providing a command interface to control an electronic device and a wireless transmitter that operates on a frequency outside of the commonly used AM/FM bands. The portable media player preferably plugs into a cradle on the portable battery charger so that the two units seamlessly act as one unit. This combination seemingly creates a new portable media player with a longer battery life and the ability to wirelessly control devices.
