Working Principle:
This item uses 3 phase brushless generator for power generation, which is commutated to charge its built-in 800mAh Ni-MH battery. External electrical source (DC 6V, DC port φ3.5*φ1.35, anod inside and cathod outside) can also be used to charge the inside battery, with charging current 150-200mA. A tact switch is used to control the lighting circuit: 2 LEDs on -1W LED on - 1W LED flashes – off . It can be also used to charge mobile phone via a charging cable and the DC socket, The charging current is 700-800mA.
