Detailed ways

Figures 1 to 4 are schematic diagrams of one embodiment of the utility model. The utility model is composed of two solar panels 9, a storage battery, a charging and discharging control circuit, and a folding bag. The folding bag is composed of at least two or more folding surfaces. , the present embodiment has three folding surfaces 1, 2, and 3. The folding surfaces are made of flexible cloth and can be folded along the folding lines 7 and 8. Each folding surface is provided with at least two layers. This embodiment consists of two It is made into cloth, and connecting lines can be set between the cloths so that the connecting parts are not exposed. Bags 10, 14, 4 are provided on the inner side of each folded surface (i.e. the front after unfolding, as shown in Figure 1). , the storage battery is placed in the bag 4 of a folding surface on one side, and the bags 10 and 14 on the other folding surfaces are transparent bags for placing the solar panel 9, the solar panel is connected with the charge and discharge control circuit through wires, and the charge and discharge control circuit is connected storage battery.

The charge and discharge control circuit is set in the control box 6, and the control box is provided with a solar output port, a DC charging port, a plurality of power supply output ports of different voltages, a power display button and a power display indicator light; the control box It is located on the inner side of the same folding surface of the storage battery. The outer side of the foldable bag is provided with a flexible handle 13. In this embodiment, the flexible handle is a handle made of cloth strips. The edge of the folded surface is provided with a plurality of flexible buckles 11. The flexible hanging buckle is a U-shaped buckle made of cloth strips. The U-shaped buckle is fixedly connected with the edge of the folding surface and can be used to fix the unfolded solar panel.
