Recharging the Power Bank
The power bank can be recharged using five input methods:
- Wall Charging: Connect the built-in USB-A input cable or a USB-C cable to a wall adapter.
- Solar Charging: Place the power bank with its solar panel facing direct sunlight. The solar charging indicator will light up green when charging. Note: Solar charging is primarily for emergency use and supplemental power, not a primary charging method due to varying sunlight intensity.
- Hand Crank Charging: Extend the hand crank handle and rotate it clockwise. This method provides emergency power when other sources are unavailable. Rotating the handle for 2 rounds per second can activate the flashlights.
