rear hand cranking flashlight
The product adopts new type rear mounted generating illumination
equipment, which reserves the traditional round-shape outline of
flashlight, and adds the shake self-generating and energy storage
system. It adopts multi-layer acceleration gear group, with light
sense and high efficiency. When shaking it for 120 cycles, (Use one
lamp, illuminate for one hour, use three lamps, illuminate for 20
minutes, use six lamps, illuminate for about 4 minutes.) The more
the shaking loops are, the faster the speed is, and the longer the
illumination time is. When the power is not enough, just shake
again. (The effect for shaking charge will be better if shutting
the power supply.)
The user can control the lamp quantity for illumination (LED Light
Emitting Diode) through the switch according to the actual
illumination environment. Press the switch once, illuminate one
lamp, press the switch twice, illuminate three lamps, press the
switch thrice, illuminate six lamps and press the switch for the
fourth time, the power is cut off.
