A photo- voltaic charger (11) has a body (12) with grips (14) extending from a central region (15). This region is complementary with a back face (16) of the telephone. The grips are complementary with the side edges of the telephone. In an end wall (17) of the body, a charging connector (18) and additional contacts (19) are provided, the latter being complementary to additional points (20) on the telephone. The charger is engaged with the telephone by sliding the one along the other, with the grips (14) engaging the casing at the edges (9, 10) of the casing. The sliding is stopped by abutment of the end wall (17) with the bottom edge (6) with the connector (18) engaging the charging point (5) and the additional contacts engaging the additional points (20). The outside surface (21) of the charger body, that is the outside of the central region is substantially covered in an array of photo- voltaic cells (22), which curve onto the sides (23) having grips (14). The cells are connected to a management circuit (24), whose output is connected to the charging connector (18). For use, the array needs to receive sun light. The telephone can be placed face down or can be stood up on end on a foot (25) provided on the end wall (17). Thus the telephone can be continuously charged when exposed to sun light. |
