  2. Solar Panel: Provides a trickle charge in direct sunlight to maintain battery life.

  3. Hand Crank Generator: Turn the crank clockwise for emergency charging. One minute of cranking provides about 10 to 20 minutes of radio playback.

  4. USB-C Charging: Connect the included USB-C cable to a 5 V DC power source for a full charge in approximately 6 to 8 hours.
