LED Cranking Flashlight (SB 3089), china LED Cranking Flashlight (SB 3089) manufacturer, LED Cranking Flashlight (SB 3089) wholesale center

Working Principle:

Cranking the handle by hand, changing speed by professional designed driving gear to drive the three-phase brushless generator to generate alternating current. Then through commutating and voltagestabilizing to change the alternating current into DC to charge its inside lithium battery, so as to achieve energy converting and accumulating.

The built-in illumination circuit is to be used to control the lighting of 5 LEDs through a touching switch. It can meet different demands of lighting. ( Offlow luminancehigh luminance )

It can also charge external things by the USB socket of the inside chargeable circuitry.

As above to realize functions as energy shifting, cranking to charge for emergency, illuminations and so on.



Functions:

1. High-luminance lighting.

2. Cranking to charge in high-efficiency.

3. Charging external things to meet an emergency. ( such as MP3, MP4, mobilephone or other digital things. )



Features:

1. Cranking for power generation, so no external batteries needed, energy accumulating by chargeable lithium battery; Green, environment friendly, economy and safety. ( common dry batteries will leak easily. ). Reuse infinitely.

2. High-luminance lighting. (5 LEDs)

3. Practical handle in exceptional size, brushless generator for power; Perfect match of light weight and high efficiency; Low noise and long lifespan.

4. Charge external things in high-efficiency.

5. USB socket output. (charge MP3, MP4, mobilephone or other digital things directly. )

6. Charging indicator.

7. Controlled by crystalline button and electric switch, comfortable.

8. Exquisite and novelty.
