<p>A power adapter (10) provides electrical power from multiple power sources. The power adapter includes first (18) and second (20) plugs adapted to be electrically coupled to first and second power sources, respectively. The power adapter is configured to provide a first power output from the first power source (e.g., airline power socket), and a second power output from the second power source (e.g., cigarette lighter socket), to the electronic device (12), depending on which power source to which the power adapter is coupled. The power adapter may also limit the first power output from the first power source to a predetermined maximum. <IMAGE></p> |
