  In the present embodiment, in the vicinity of the first and second light transmission parts S1, S2 on the fifth outer surface 160e and at positions corresponding to the first and second portable terminal input connectors 120a, 120b, First and second display information indicating the types of the power adapters 410a and 410b of the first and second portable terminals 400a and 400b (for example, the type of the portable terminal itself and characters indicating the company name of the mobile communication carrier) M1 and M2 are respectively displayed (see FIG. 2A). In this way, while maintaining compactness, the position display indicating where the first and second portable terminal input connectors 120a and 120b are located is associated with the first and second light transmission parts S1 and S2. In addition, it is possible to perform a display that also serves as a type display indicating which type the power adapters 410a and 410b of the first and second portable terminals 400a and 400b are, and the convenience when charging the storage battery 210 is increased accordingly. Can be improved.

  In the present embodiment, the first portable terminal input connector 120a can use a common connector among a plurality of mobile communication carriers (specifically, between Company A and Company B). It has become. Therefore, the first display information M1 (XXX) is printed, stamped or engraved with “type of mobile terminal of company A / company name of company B”. In addition, since the second portable terminal input connector 120b is used only by a single mobile communication carrier (specifically, company C), the second display information M2 (ΔΔΔ) includes “ Only company name “C” is printed, affixed or stamped.

  Note that light emission by the third light emitting element device LED3 is charged to the storage battery 210 near the third light transmission part S6 on the fifth outer surface 160e and between the first display information M1 and the second display information M2. Display information M5 (in this case, the word “RECCHARGE”) indicating that the state is to be notified is printed, affixed or stamped.

  In the present embodiment, as shown in FIG. 2B, it corresponds to the first and second portable terminal input connectors 120a and 120b on the other outer surface (here, the sixth outer surface 160f of the back case 162). The third and fourth display information indicating the types of the power adapters 410a and 410b of the first and second portable terminals 400a and 400b (for example, the type of the portable terminal itself and the mobile communication carrier) Characters indicating company names) M3 and M4 are displayed (specifically, printing, sticker attachment or engraving). By doing so, even if the charging power connection device 100 faces the back side, the position display of the first and second portable terminal input connectors 120a and 120b and the corresponding first and second portable terminals 400a and 400b. The type of the power adapters 410a and 410b can be displayed, and further convenience improvement when charging the storage battery 210 can be realized.

  In the present embodiment, charging circuit 130 shown in FIG. 4 includes power supply device 300 and power supply adapter 410 (410a, 410b) of portable terminal 400 (here, first and second portable terminals 400a, 400b). When two or more devices are connected, a first diode D1 and a second diode D2 (D2a, D2b) are provided as backflow prevention diodes for preventing a backflow of current to the connected devices. .

  Specifically, the first diode D1 is connected in series to the power supply line PW between the USB input connector 110 and the first capacitor C1 so that the anode side is the USB input connector 110 side. The second diode D2 (D2a, D2b) is connected to the power lines PW, PW between the first resistor R1 and the portable terminal input connector 120 (120a, 120b), and the anode side is the portable terminal input connector. They are connected in series so as to be on the 120 (120a, 120b) side.

  Thus, the charging circuit 130 is provided with the first diode D1 and the second diode D2 (D2a, D2b), so that the USB port 310 of the power supply device 300 remains connected to the USB input connector 110 and the power adapter. At least one of the plugs 411a and 411b of 400a and 400b (for example, the plug 411b of the power adapter 400b) is also connected to a corresponding connector (for example, the connector 120b) of the first and second portable terminal input connectors 120a and 120b. When connected, the current flows backward from the higher potential to the lower one of the output voltage from the USB port 310 and the output voltage from at least one of the plugs 411a and 411b (for example, the plug 411b). This can be prevented. Alternatively, when the USB port 310 of the power supply device 300 is not connected to the USB input connector 110, both the plug 411a of the power adapter 400a and the plug 411b of the power adapter 400b are input for the first and second portable terminals. When each of the connectors 120a and 120b is connected, current flows backward from the higher potential to the lower one of the output voltage from the plug 411a of the power adapter 400a and the output voltage from the plug 411b of the power adapter 400b. Can be prevented.

  As described above, since the charging circuit 130 includes the first diode D1 and the second diode D2 (D2a, D2b), the power supply device 300, the power adapter 410a of the first mobile terminal 400a, and the second mobile phone. Even when two or more devices are connected to the power adapter 410b of the terminal 400b, backflow to the connected devices can be easily prevented.

  In the present embodiment, the charging circuit 130 causes the backflow of current from the storage battery 210 of the electronic cigarette 200 to the connected device among the power supply device 300 and the power supply adapter 410 (410a, 410b). Is to prevent.
