Abstract
The solar charger is provided with a case 1 that can hold a rechargeable battery 5 in a removable fashion, and a solar cell 4 to supply charging power to the rechargeable battery 5 loaded in the case 1. The case 1 is formed in a shape having a bottom surface 2 and at least two tapered surfaces 3 with different slope angles α with respect to the bottom surface 2, and the solar cell is disposed on the bottom surface 2. The angle of inclination θ of the solar cell 4 provided on the bottom surface 2 of the solar charger is changed by disposing a tapered surface 3 having a different slope angle α on a flat surface.
Claims22
