Cranking Radio (SB 1085), china Cranking Radio (SB 1085) manufacturer, Cranking Radio (SB 1085) wholesale center

Working principle:

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

The inside radio circuit can achieve reception function of the two wave band ( FM/WB ). It can search stations automatically: From low-end frequencies to high-end frequencies ( locked and stopped automatically when radio stations had been recieved ). Press the reset button to search again.



Function:

1. FM(frequency modulation)/WB(weather) Two wave bands regulate reception automatically.

2. Cranking for power generating and accumulating efficiently.

Features:

1. Cranking for power generation, never need batteries, keep energy by built-in rechargeable NI-MH battery; Green, environment friendly, economy, safety. (the common battery will leak easily). Reuse limitlessly.

2. High sensitive FM(frequency modulation)/WB(weather) Two wave bands reception, catch every wonderful electric wave anywhere at any time.

3. Huge caliber loudspeaker, the sound is silvery and resounding, sheer innervation.

4. Searching for radio program automatically, the operation method is simple and convenient.

5. Professional handle design and brushless power generation. It is the perfect combination of light weight and high efficiency. Low noise and long life-span.

6. The style is lucidity.
