Abstract

The invention discloses a portable solar charger, comprising a solar cell panel, an energy storage module and a charging port. The solar cell panel can convert light in an environment into electric energy and transmit the electric energy to the energy storage module for storage, so an electric device can be charged whenever and wherever possible. The energy storage module charges a to-be-charged electric device through the charging port. A first electric energy control module is arranged between a solar cell and the energy storage module. A second electric energy control module is arranged between the energy storage module and the charging port. Electric energy can be transmitted unidirectionally due to existence of the first electric energy control module and the second electric energy control module, thereby preventing a current from flowing back. According to the charger provided by the invention, the solar energy can be converted into the electric energy, the electric energy is stored in the cell and the to-be-charged device also can be directly charged, so the utilization efficiency of the solar charger is greatly improved; and the charger is compact in structure and convenient for carrying, is suitable for carrying when going out and has a relatively good application market.
