PURPOSE: A computer equipped with a USB connector having no current limit is provided to conveniently charge batteries of a smart phone and a tablet PC through the USB connector of the computer by increasing an output current of the USB connector. CONSTITUTION: A USB port(22) includes a first power terminal, a first ground terminal, and a first data terminal pair. The first power terminal receives the output of a power supply unit(30) through a current limiting circuit. A USB connector(100) includes a second power terminal, a second ground terminal, and a second data terminal pair corresponding to the terminals of the USB port. The second data terminal pair is connected to the first data terminal pair. A switching unit(120) selectively connects the second power terminal of the USB connector with an output terminal of the power supply unit or the first power terminal.
