2. Setup
Battery Installation and Charging:
The Nitecore P20iX comes with an NL2150HPi Lithium Ion battery pre-installed. Before first use, it is recommended to fully charge the battery.
- Locate the USB-C charging port on the flashlight body. It is typically covered by a protective rubber flap.
- Gently lift the rubber flap to expose the USB-C port.
- Connect the included USB-C charging cable to the flashlight's port and the other end to a USB power source (e.g., wall adapter, computer USB port).
- The charging indicator light will illuminate to show charging status. Refer to the indicator light section in the specifications for details.
- Once charging is complete, disconnect the cable and firmly press the rubber flap back into place to ensure water and dust resistance.
The P20iX can also use 2 x CR123 batteries with the included adapter, though performance may vary. Always ensure correct polarity when inserting batteries.

4. Maintenance
To ensure the longevity and optimal performance of your Nitecore P20iX flashlight, follow these maintenance guidelines:
- Cleaning: Regularly wipe the flashlight body with a clean, soft cloth. For stubborn dirt, a slightly damp cloth can be used. Avoid abrasive cleaners.
- O-Ring Lubrication: Periodically lubricate the O-rings with silicone grease to maintain water resistance.
- Thread Cleaning: Keep the threads clean and free of debris.
- Charging Port: Always ensure the USB-C charging port cover is securely closed when not charging to maintain its IP68 waterproof and dustproof rating.
- Battery Care: If storing the flashlight for an extended period, remove the battery to prevent leakage. Recharge the battery every few months to maintain its health.
The P20iX is designed with IP68 waterproof and anti-impact protection, making it highly durable. However, proper care will extend its lifespan.
5. Troubleshooting
If you encounter issues with your Nitecore P20iX, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Flashlight does not turn on or is dim. | Low battery, loose tailcap, or dirty contacts. | Charge the battery. Tighten the tailcap. Clean battery contacts and threads with a clean cloth. |
| Turbo mode dims quickly. | Overheating protection activated. | This is normal. The flashlight reduces output to prevent damage from excessive heat, especially in Turbo mode. Allow it to cool down. |
| Accidental Strobe activation. | Mode button pressed too quickly or accidentally. | Be mindful of the Mode button's sensitivity. Practice using the switches to avoid unintended activation. |
| Charging not working. | Cable issue, power source issue, or dirty port. | Try a different USB-C cable or power source. Ensure the charging port is clean and free of debris. |
If the issue persists after trying these solutions, please contact Nitecore customer support for further assistance.
