In emergency disaster prevention scenarios, such devices can assist users in obtaining crucial information such as government emergency broadcasts and meteorological warnings. For instance, in the event of power outages caused by typhoons, earthquakes, or rainstorms, they can provide short-term power supply through hand-cranking, maintaining the radio’s operation to receive rescue instructions. Simultaneously, the lighting function can provide basic light, and the flashing alarm serves as a distress signal for location determination. ‌
