A hand-cranked power source intended for use in emergency situations to generate electrical energy. The power source features a lightweight construction as well as the ability to generate a reasonable amount of power. The preferred embodiment couples an input drive shaft to a harmonic drive system having a high speed output shaft. Upon the output shaft are preferably mounted samarium cobalt magnets forming the rotor of a three phase alternator. The output of the alternator may be utilized to power a field device, such as a radio, or the like, or may be used to charge fast-charging batteries.
