• 【Diversified power supply methods】 The emergency solar crank radio is equipped with a 20000mAh rechargeable battery that can be charged through a USB C cable, making it safer and more efficient. The top is equipped with high-efficiency solar panels, which can convert solar energy into electricity to power the radio as long as there is sunlight shining on it. Even in the absence of sunlight, it can quickly generate electricity by hand cranking. Hand cranking for a few minutes can produce enough electricity for the radio to be used for a short period of time, ensuring that it can be used normally in cloudy, indoor and other environments.
