Description

  The present invention mainly relates to a charging base for setting and charging a mobile device such as a mobile phone.

The charging stand includes positive and negative output terminal portions that are in contact with a power supply terminal of a mobile device to be mounted. When a metal comes into contact with the positive and negative output terminals and shorts, a large short current flows. In addition, when the voltage at the positive and negative output terminal portions is high, there is a possibility of electric shock when touched with wet hands.
