A portable power apparatus 3 comprises a battery cell 23 for storing electrical charge, an output 8A for delivering the stored electrical charge to external equipment and a generator unit 21 for recharging the battery cell. A spindle system 11, provided (figs 11a-11m not shown) for delivering rotation to a rotor 19 of the generator unit, comprises first and second coaxial spindles 11A, 11B, each connected to the rotor, the second spindle being connected to the rotor via a gearing system 21 configured to deliver a different angular velocity to the rotor than that of the first spindle. The first and second spindles each having an engagement portion 12, 113 that projects from the portable power unit for connection to an external attachment. The first spindle may be connected to a wind/water turbine and the geared input to a crank handle. External power may be supplied to the battery from a further power source (solar panel) via the connector 31, control circuit 13 allowing the battery to be simultaneously charged from the generator and the supply. Details of the connector and its output socket are additionally disclosed in Figs 3,5 (not shown). |
