DYNAMO TORCH RADIO ORANGE/BLACK
WORKING PRINCIPLE
This product adopts the principle of cranking for power by 3 brushless generator which after commutating and filtering to charge its built-in 80 mAh/3.6v Ni-MH rechargeable battery, the energy stored is used as the power source of LED and FM/AM radio. The radio circuit adopts the specified radio CMOS chip CD2003 to realise FM/AM radio function, the wave band can be changed by the "AM / FM switch", mechanical tuning and speaker output.
FUNCTIONS
- Cranking to charge the built-in 80mAh/3.6V Ni-MH rechargeable battery
- Three lighting model: 1 LED lighting, 3 LEDs lighting, 3 LEDs flashing.
- FM/AM radio function
FEATURES
