Connection Steps:
- Identify the charging port on your BlueParrott headset (e.g., B650-XT, B450-XT) or Jabra headphones (e.g., Elite 75t, Elite 85t).
- Select the appropriate connector (Micro USB or USB-C) from the 2-in-1 cable.

- Connect the standard USB-A end of the cable to a compatible USB power source, such as a wall charger, computer USB port, or power bank.
4. Operating Instructions
Once connected, your device should begin charging automatically. The cable supports fast charging up to 2 Amps, which can significantly reduce charging time compared to standard cables.
Charging Process:
- Ensure the power source is active.
- Monitor your device's charging indicator (usually an LED light) to confirm it is receiving power.
- Charging times will vary depending on your device's battery capacity and the power output of your USB source.
- Disconnect the cable once your device is fully charged to conserve energy and prolong battery life.

5. Maintenance
Proper care and maintenance will extend the life of your charging cable.
- Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent internal wire damage.
- Cleaning: Use a soft, dry cloth to clean the cable and connectors. Do not use liquid cleaners or solvents.
- Handling: Always grasp the connector head when plugging or unplugging the cable. Avoid pulling on the cable itself, as this can damage the internal wiring.
- Inspection: Periodically inspect the cable for any signs of wear, fraying, or damage to the insulation or connectors. Discontinue use if any damage is observed.
6. Troubleshooting
If you encounter issues with your charging cable, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not charging | Incorrect connector used; loose connection; faulty power source; damaged cable; device issue. | Ensure the correct connector (Micro USB or USB-C) is used. Check that both ends of the cable are securely plugged in. Try a different USB power source or wall adapter. Inspect the cable for visible damage. Test with another device if possible. |
| Slow charging | Low power output from source; device drawing too much power; background apps on device. | Use a USB power source with at least 2A output. Close unnecessary applications on your device. Ensure the cable is not excessively long or damaged. |
| Cable feels hot | Overload; faulty cable; environmental factors. | Immediately disconnect the cable from both the device and power source. Do not use the cable if it consistently overheats. Contact support if the issue persists. |
