Abstract
A portable photovoltaic battery recharger for simultaneously recharging a plurality of rechargeable batteries having different sizes and respective optimum charging current levels. The battery recharger includes a plurality of photovoltaic solar cells having a plurality of different selectively chosen surface areas for generating the respective optimum charging current levels when insolated, and battery receptacles for holding the plurality of rechargeable batteries in a recharging position. The plurality of solar cells are connected to the battery recepatcles to transmit the charging current generated by each photovoltaic cell to respective ones of the plurality of battery receptacles such that batteries held in the battery receptacles are charged at respective optimum charging current levels.
