Portable apparatus for generating electricity

A portable apparatus for generating electricity is provided comprising an electrical energy-generating device for generating electrical energy in response to input mechanical action. The apparatus comprises a drive mechanism having an elongate flexible member provided as a closed endless loop. A portion of the elongate flexible member is exposed so as to enable a user to grasp and pull said portion downward by a distance of at least 30 cm. The drive mechanism supplies the said mechanical action to the electricity-generating device, wherein said mechanical action is provided by user applying a downward force to the elongate flexible member so as to cause the elongate flexible member to move with respect to the mounting element. A re-chargeable battery is further provided for storing the electrical energy generated by the electrical energy-generating device. A mounting element enables the apparatus to be supported at a suspended position relative to the ground during use.
