<p>A device for charging a battery with one of a direct current and an alternating current includes a power adapter for providing a power signal and a power signal determining unit. The power signal determining unit determines whether the power signal is an alternating current or a direct current and a power transmission route selector selects a first power transmission route for the direct current and a second power transmission route for the alternating current. A charger receives the power signal to charge the battery. A power selecting unit includes a unit for transmitting the power signal from the power adapter to the battery through the charger when the first power transmission route for the alternating current signal is selected. A unit for transmitting the power signal from the power adapter to the battery when the second power transmission route for the direct current signal is selected.</p> |
