ABSTRACT:
A three-way power source circuit for portable electronic equipment, such as a radio, is disclosed. The power source circuit comprises a solar energy cell, a rechargeable battery and a standard nonrechargeable dry cell. A transistor couples the solar cell and rechargeable battery to a common point of the circuit, and a second transistor couples a standard dry cell to the common point. The common point provides one of the power output lines to the portable electronic equipment. The solar cell, rechargeable battery and standard dry cell return lines are coupled to a further common point which serves as the return line for power supplied to the portable electronic equipment. Switches are provided for eliminating the flow of current to the portable electronic equipment. The three-way power source circuit allows the solar cell to recharge the rechargeable cell when sufficient light is present. When insufficient light is present, the standard dry cell or the rechargeable battery, if it is sufficiently charged, provide power for the portable electronic equipment. If the standard dry cell is depleted, then the rechargeable cell/or the solar cell provide the primary power for the portable electronic equipment.
