What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a solar phone charger been patented?” but “has my combination of features been described before?” Consumer electronics are among the most heavily patented areas; the specific circuit, mounting, or interaction is what distinguishes a design.
