Solar Radio Function: 1. Solar energy and hand self-generation dual-charging, no external batteries, rechargeable batteries and energy storage; green, environmental, economic, and security (general dry Easy to leakage), can be recycled; 2. The circuit power consumption is very low, the battery when electricity is not available real-time in the sun listening to the radio FM tuner green LED instructions; blue LED charging instructions. 3. Longer the handle, hand noise, power generation, high efficiency, low power consumption; can be realized a long time to listen to 4. A long rod antenna, enhanced FM reception capability; speaker / earphone dual mode sound output, adjustable volume. 5. Use of high-quality radio integrated circuits, high-sensitivity FM (FM) / AM (MW) 2-band radio; anywhere, anytime to capture every exciting waves. 6. Can be an external power supply charge. Technical parameters: FM (frequency modulation) Sensitivity:> 10uV AM (medium wave) Sensitivity:> 1.5mV / m FM (frequency modulation) receiver frequency range :88-108MHz AM (MW) to receive frequency range :530-1650KHz Audio Output Power> 100mW Hand 1 minute radio time (2.5 3 laps / sec) about 20 minutes Time of 5 hours sunshine radio (500W/M2) about 40 minutes Solar Charge Maximum Current: 40mA Sunshine is full time (500W/M2) :20-30 Xiao Shi The battery is fully charged Radio time: about 7 hours Input Voltage: 5v Outside the internal battery is full time: around 8 hours Built-in Speaker Diameter: Φ40mm Built-in Battery Specifications: 300mAh (milliamperes), 2.4V (volts) Size: 130 * 73 * 41mm Net Weight: 206g Gross Weight: 253g Packing information: 60 / Box Net Weight: 13.5KG Gross Weight: 16 KG Carton size: 46 * 36 * 53cm
