Frequency Coverage: Local FM stations may go off-air during emergencies, so choose an all-band radio that supports Medium Wave (AM) and Shortwave (SW) to receive broadcasts and weather alerts from more distant areas. It is even better if the radio supports NOAA weather bands (a feature found on some models available in China).
Power Supply: Prioritize models that support multiple power sources-such as hand-cranking, solar power, and dry-cell batteries or USB charging-to ensure continued operation during power outages or network failures. Opt for devices that use standard AA batteries or high-capacity 18650 lithium batteries for easy replacement and extended runtime.
Durability and Portability: Emergency equipment must withstand impacts and harsh conditions; prioritize models with rugged, waterproof casings and compact designs. Models featuring a built-in flashlight, an SOS alarm, and the ability to reverse-charge mobile phones offer greater practical value.
