Before first use, fully charge the flashlight. Connect the included Type-C charging cable to the flashlight's charging port and a compatible USB power source (e.g., PC, laptop, power bank, USB hub). The charging indicator will show the charging status. A full charge typically takes approximately 2.5 hours.
3.2 Fluorescent Shell Activation
The flashlight features a fluorescent shell that glows in the dark. To activate this feature, expose the flashlight to a light source (such as sunlight or a bright lamp) for a period. The shell will absorb the light and then emit a glow in dark environments, making it easier to locate.

5. Maintenance
5.1 Charging
To maintain optimal battery life, charge the flashlight regularly, especially when the light output appears dim. Avoid completely draining the battery for extended periods.
5.2 Cleaning
Wipe the flashlight's exterior with a soft, damp cloth to remove dirt or debris. Do not use harsh chemicals or abrasive materials, as they may damage the finish or internal components.
5.3 Water Resistance
The flashlight is IP65 waterproof, meaning it is protected against low-pressure water jets from any direction and is dust-tight. While it can withstand rain and splashes, it is not designed for submersion in water. Ensure the Type-C charging port cover is securely closed to maintain water resistance.
6. Troubleshooting
- Flashlight does not turn on: Ensure the battery is fully charged. Connect the flashlight to a power source using the Type-C cable and allow it to charge for at least 30 minutes before attempting to turn it on again.
- Light output is dim: This indicates a low battery. Recharge the flashlight.
- Flashlight gets warm during prolonged use: High-brightness LED flashlights can generate heat, especially in Turbo or High modes. This is normal. If the flashlight becomes excessively hot, reduce the brightness level or turn it off to allow it to cool down.
- Charging not working: Check the Type-C cable and the power adapter for damage. Try a different cable or power source. Ensure the cable is fully inserted into the charging port.
