3. Setup

3.1 Initial Charge:

1. Connect the Nitecore NB Plus to a power source (e.g., wall adapter, computer USB port) using a compatible USB-C cable.
2. The blue indicator lights on the power bank will flash to show the charging status. All four lights will remain solid when the power bank is fully charged.

3.2 Checking Battery Level:

• Briefly press the power button located on the side of the power bank. The blue indicator lights will illuminate, showing the current battery level. Each light typically represents approximately 25% of the battery capacity.

4. Operating Instructions

4.1 Charging External Devices:

1. Connect your external device (e.g., smartphone, tablet, headlamp) to the NB Plus using a compatible USB-A or USB-C cable.
2. The NB Plus will automatically detect the connected device and begin charging. The indicator lights will show the remaining power of the power bank.
3. The USB-C port functions as both an input and an output, supporting up to 22.5W output. The USB-A port is output-only, also supporting up to 22.5W output.

4.2 Simultaneous Charging and Discharging:

The Nitecore NB Plus supports pass-through charging, meaning it can be recharged itself while simultaneously providing power to an external device. This feature allows for continuous power management.

5. Maintenance

5.1 Cleaning:

To clean the NB Plus, gently wipe its surface with a soft, dry cloth. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the device's finish or internal components.

5.2 Water Exposure:

While the NB Plus is IPX7 waterproof, it is crucial to ensure all ports (USB-A and USB-C) are completely dry before connecting any cables or attempting to charge the device or external devices. Water in the ports can cause short circuits or damage.

5.3 Storage:

Store the power bank in a cool, dry environment, away from direct sunlight, high temperatures, and high humidity. For prolonged storage periods, it is recommended to charge the device to approximately 50% capacity every three months to maintain battery health and extend its lifespan.

6. Troubleshooting

6.1 Device Not Charging:

• Check Power Bank Charge: Ensure the Nitecore NB Plus has sufficient charge by pressing the power button and observing the indicator lights.
• Cable Connection: Verify that the charging cable is securely connected to both the power bank and the external device.
• Try Different Cable/Port: Test with a different charging cable or try using the other available port on the power bank.
• Device Compatibility: Confirm that your external device is compatible with the power bank's output specifications (voltage and current).

6.2 Slow Charging:

• Cable Quality: Ensure you are using a high-quality cable that supports fast charging protocols (PD, QC 3.0, SCP).
• Device Support: Confirm that your external device supports fast charging. Older devices may charge at a slower rate.
• Environmental Factors: Extreme temperatures (very hot or very cold) can affect charging efficiency. Use the power bank within its recommended operating temperature range.
