The invention discloses a concentrating solar charger, comprising a light reflecting plate and a solar battery panel; the light reflecting plate is a condenser combined with a plurality of curve faces; after the sunlight enters to the light reflecting plate, and then gathers on the solar battery panel arranged in the middle of the light reflecting plate through reflection and kept in parallel to the incident light direction; multiple solar battery components are arranged on a desk, and output to a power device after connection in series and in parallel. The charger of the invention is added with a light concentrating structure, thus the photoelectric conversion efficiency of the charger is improved.
