The case 10 is made of, for example, aluminum and is formed in a trunk-type handbag (attached case) -like shape. As shown in FIGS. 1 to 3, the case 10 includes a case body 11 and a lid 12.

  The case main body 11 and the lid portion 12 are formed in a substantially square container shape, and the depth of the case main body 11 is formed deeper than the depth of the lid portion 12. The case main body 11 and the lid portion 12 are connected by a hinge 13 so as to be rotatable around one axis.

  The hinge 13 (angle adjusting member) has an angle adjusting function for holding the lid 12 at an arbitrary inclined position with respect to the case main body 11 by friction of its constituent members. The side wall (front wall) opposite to the side wall (rear wall) provided with the hinge 13 of the case body 11 is provided with a carrying handle 14 and a lock for integrating with the lid 12 in the closed state. A metal fitting 15 is provided. The solar panels 21 and 22 are fixed in the storage spaces S in the case main body 11 and the lid portion 12 in a state where the solar panels 21 and 22 are stored, respectively.

  The solar panels (solar cells) 21 and 22 are formed by laminating semiconductor materials made of, for example, polycrystalline silicon (or single crystal silicon) into a thin plate shape, and generate electric power upon receiving sunlight. In addition, the rated output of each solar panel 21 and 22 is set to 10W.

  As shown in FIG. 4, the solar panels 21 and 22 are connected to the battery 23 via the controller 24 and are connected to the inverter 25 via the controller 24. The battery 23, the controller 24, and the inverter 25 are fixed to the case main body 11 while being accommodated in the accommodation space S in the case main body 11. The solar panel 21 is fixed to a portion near the opening 11a of the case body 11 in a state of covering the battery 23, the controller 24, and the inverter 25 (see FIG. 2).

  The battery 23 is a lead storage battery having a capacity of 20 Ah and an output voltage of 12 V, for example, and charges the electric power generated by the solar panels 21 and 22. The controller 24 includes a charging circuit that charges the battery 23 efficiently. For example, the charging circuit performs constant current charging when the battery 23 is empty, and performs constant voltage charging when the voltage of the battery 23 is high to some extent. The inverter 25 converts the power charged by the battery 23 into alternating current (AC 100 V output) and feeds (discharges) the electric power to the outside. The inverter 25 is set to a maximum rating of 400 W, for example.

  A switch 26, light-emitting diodes 27 and 28, and a fan 29 are connected to the controller 24 via electric wiring, and a power supply outlet 31 is connected to the inverter 25 via electric wiring.
