  The present invention relates to a charging device for charging portable electronic devices such as a mobile phone, a smartphone, a portable music player, a portable game machine, a digital camera, and a tablet PC.

  In recent years, small electronic devices such as mobile phones, smartphones, portable music players, portable game machines, digital cameras, and tablet PCs have become widespread. Since such a small electronic device is intended to be carried and used, the built-in storage battery (secondary battery) is used while being charged as necessary. As a charger for charging such a secondary battery, one that is connected to a commercial power source and AC / DC converted to perform charging is generally used. However, it is impossible to charge in a place where a commercial power source cannot be obtained.

  Therefore, a portable information terminal charger that can be charged even in a place without a commercial power supply has been proposed (for example, Patent Document 1).

  The portable information terminal charger described in Patent Document 1 has a built-in secondary battery in a charging AC adapter, and includes a DC connector for a mobile phone and a USB (Universal Serial Bus) port for other portable information terminals. Depending on the situation, DC power supply from the AC power source via the DC connector or USB port, DC power supply from the built-in secondary battery via the DC connector or USB port, or charging from the AC power source to the secondary battery should be selected It is configured to be able to.

  In recent years, as shown in FIG. 12, a charger 1 is proposed in which the charging AC adapter unit 2 and the secondary battery unit 3 are formed in separate casings, and connected to each other as necessary. Has been. In this charger 1, the secondary battery unit 3 having the AC adapter unit 2 and the USB output terminal 4 is connected to charge the secondary battery from the commercial power source. After the charging is completed, the AC adapter unit 2 is removed. Only the secondary battery unit 3 can be taken out. When the user is away from home, the portable electronic device can be supplied with electric power stored in the secondary battery unit 3.
