Solar charger capable of charging various batteries

The invention discloses a portable solar charger capable of charging batteries of mobile equipment, belongs to the technical application field of solar batteries, and aims to equip a universal photovoltaic charging controller for battery development of portable communication equipment. The solar charger capable of charging various batteries is mainly characterized in that an IC (integrated circuit) module mounted in a box body comprises an MCU (microprogrammed control unit)-controlled MPPT (maximum power point tracking) solar maximum power output charging unit, a DC/DC control unit, a voltage and current detection unit, and a display and warning unit. Multidimensional folded flexible solar battery components or other power supplies are plugged in plug-in PV input interfaces; the battery types, voltage and capacities controlled by the rear end are various; and the front end adopts photovoltaic input, so that maximum photovoltaic input when the charger is used for batteries with different voltage can be achieved. The controller is applied in a field environment, has good water resistance, and is concise in display and convenient to operate and carry.
