[0033] According to an embodiment of the present utility model, as Figures 1 to 4 shown, a solar cell charger includes:

[0034] A charging box 1, on which a battery slot 5 is provided;

[0035] A photovoltaic panel 2, which is electrically connected to the charging box 1;

[0036] The photovoltaic panel 2 is flexibly connected to the edge of the charging box 1. When the photovoltaic panel 2 rotates around the flexible connection position to the back of the charging box 1, the back of the photovoltaic panel 2 is adsorbed to the back of the charging box 1.

For convenient storage, in this embodiment, the length and width of the photovoltaic panel 2 are the same as those of the charging box 1, and the photovoltaic panel 2 is flexibly connected to the edge of the charging box 1. When the photovoltaic panel 2 rotates, it can be adsorbed on the back of the charging box 1. In this implementation, the photovoltaic panel 2 can be attached to the back of the charging box 1 by magnetic attraction or negative pressure adsorption. Through the above design method, the size of this solar charger can be controlled within a relatively small range, making it convenient for users to carry and store when using it outdoors.
