1. An apparatus comprising:
a) a hand crank attached to a main spring;
b) the main spring attached to a first chain of gears;
c) the first chain of gears attached to a generator;
d) the generator attached with wires to an electronic circuit;
e) the first chain of gears attached to a second chain of gears;
f) the second chain of gears attached to a clutch wheel;
g) the clutch wheel attached to a clutch mechanism, the clutch mechanism comprising a clutch latching mechanism and a bi-directional solenoid;
h) the clutch latching mechanism linked to the hand crank by the action of removing the winding handle from the clutch mechanism when unfolding the hand crank into the winding position;
i) the bi-directional solenoid attached with wires to an electronic circuit controlling the activation of the clutch mechanism;
j) the electronic circuit controlling the activation of the bi-directional solenoid, storing electricity, and providing multiple output voltages;
k) the electronic circuit further comprising:
a) a storage capacitor;
b) a first under-voltage detector to detect a low voltage condition in the storage capacitor;
c) a second under-voltage detector to detect a load on the primary power output
d) a third under-voltage detector to detect a load on a USB power output connector;
e) an over-voltage detector to protect the electronic components;
f) the generator attached to the electronic circuit;
g) a voltage reversing switching matrix attached to the bi-directional solenoid.
