2. Related Art
In recent market, many electronic products have fixed chargers, but various chargers easily result in inconvenience in using, and the chargers of the electronic products cannot be shared. For example, for a tablet computer iPad produced by Apple Inc., when iPad is connected to non-apple computer without a special design, the information showing that the charging cannot be performed are displayed. Therefore, iPad may be charged when being connected to an apple computer or by utilizing an original manufacturer charger. Therefore, when having many electronic devices, a user also needs to have various chargers, thereby resulting in the inconvenience in using
