Battery life varies by usage: radio playing lasts 24-30 hours, flashlight mode 10-15 hours, and reading lamp 20-25 hours. In standby mode, the battery maintains charge for several months without significant drain.

Yes, the USB output port charges external devices while the radio operates simultaneously. However, this drains the internal battery faster, so carefully monitor the battery indicator lights to avoid unexpected power loss.

In direct sunlight, the solar panel generates enough power to sustain radio listening indefinitely. Full battery recharge from solar takes 40-50 hours of optimal sun exposure, making it best for supplemental charging.

One minute of consistent hand cranking provides approximately 15-20 minutes of radio listening, 5-8 minutes of flashlight use, or enough power to make a brief emergency phone call when needed most.

The radio receives NOAA broadcasts when tuned to weather band frequencies (162.400-162.550 MHz). You manually tune to your local weather channel, but once tuned, all emergency alerts broadcast automatically with priority.

The AlertWavi is splash-resistant and withstands rain or brief water exposure, but it's not fully waterproof for submersion. Keep USB ports covered when not in use for maximum protection against moisture.

The SOS alarm exceeds 120 decibels—comparable to a car horn or emergency vehicle siren. It's intentionally loud enough to attract attention from hundreds of meters away in outdoor emergency environments.

The AM/FM bands work worldwide for standard radio. However, NOAA weather band is North America-specific (US, Canada, Mexico). The power bank and lighting functions work everywhere, but weather alerts only function domestically.
