- Solar Charging: Place the flashlight with its solar panels facing direct sunlight. The solar panels on the back will absorb solar energy to charge the battery. This method is ideal for outdoor charging when other power sources are unavailable.



4. Operating Instructions
- Main Light Operation:
- Press the Main Switch (power button) to cycle through the main light modes: Strong light > Medium light > Low light > Fast flash.
- Press again to turn off the main light.
- COB Light Operation:
- Press the COB Switch (light bulb icon button) to cycle through the COB light modes: White strong light > White weak light > Red light > Red and blue light flash.
- Press again to turn off the COB light.
- Zoom Function:
- To adjust the beam, gently push or pull the head of the flashlight. Pushing the head forward will narrow the beam for a long-range spotlight (zoom in). Pulling it back will widen the beam for a broad floodlight (zoom out).
- Power Bank Function:
- Open the rubber cover on the side to access the USB output port.
- Connect your mobile phone or other USB-powered device to the USB output port using a compatible cable. The flashlight's internal battery will then charge your device.



5. Maintenance
- Cleaning: Regularly wipe the flashlight with a clean, soft cloth to remove dirt and water. This helps maintain its performance and appearance.
- Battery Care: If the flashlight will not be used for an extended period, ensure the battery is charged periodically to prevent deep discharge and prolong battery life.
- Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting
- Problem: The flashlight does not turn on or the light is weak.
- Solution:
- Check the battery level on the OLED display. If it's low, charge the flashlight using either Type-C or solar charging methods.
- Ensure the battery is properly connected internally.
- If the light is still weak after charging, the battery might be old or damaged and may need replacement.
- Problem: The flashlight is not charging.
- Solution:
- Verify that the Type-C cable is securely connected to both the flashlight and the power source.
- Try a different Type-C cable or power adapter.
- For solar charging, ensure the solar panels are exposed to direct sunlight.
- If the battery is completely dead (deeply discharged), it might take longer to initiate charging.
- Problem: The discharge time is short.
- Solution: This indicates the battery capacity might be reduced due to age or frequent deep discharges. Ensure the battery is fully charged before use. If the problem persists, the battery may need replacement.
