Abstract: A power supply for a portable computer or other electronic device of a type having an integral external housing within which the electronic components of the device are encased. The power supply comprises a mounting panel having a front surface and a back surface and side flanges disposed on the mounting panel to permit temporary attachment of the power supply to the housing of an electronic device. The back surface of the mounting panel faces toward the electronic device housing when the power supply is attached to the housing of the electronic device. At least one solar panel is attached to the mounting panel facing away from the electronic device when the power supply is attached to the housing of the electronic device. The solar panel is capable of producing an electrical power output through the conversion of solar energy to electrical energy.

Abstract: A portable power supply that includes at least one solar panel assembly that is capable of producing an electrical output through the conversion of solar energy to electrical energy. The power supply further includes power transmission means which is typically an electrical cable that will supply the power output of the solar panel to an electrical energy consuming device such as a portable computer or a battery for use therewith. The portable power supply further includes a case having at least two opposing side panels and includes solar panel assembly attachment means permitting the mounting of a solar panel assembly. The solar panel assembly typically comprises a photovoltaic panel attached to a backing panel. Backing panels utilized in the solar panel assembly may also be foldable, thus protecting the attached photovoltaic panel within the folded sections of the backing panel.
