Power unit and electronic equipment comprising the same

摘要

It comprises an input means (103) for inputting kinetic energy or force and converting it into a rotary motion, a gear train mechanism (106) for increasing a speed of the rotary motion, a generator (104) for converting the kinetic energy of the rotary motion whose speed has been increased into electricity, an electrical control circuit (105) for stabilising voltage and current of the generator and a secondary cell (110) for charging and discharging electricity. The speed-increasing multiplying factor is from 50 times to 100 times.
