USD - Solar / Crank energy radio AM/FM


Description : 

This product adopts the principle of the hand cranking and solar-energy for power generation, to charge its built-in 300mah/2.4V Ni-MH battery. Use the circuit with high-powered radio CMOS chip CXA1691BM, via the third class switch to switch frequency : FM-AM-WB(weather frequency), handling the knob to tune the frequency and volume, the sound will be output via the speaker or earplug double ways.
