5. Troubleshooting
If you encounter issues with your SMALLRIG USB-C cable, please refer to the following common troubleshooting steps:
- Cable Not Charging:

- Check if the device you are trying to charge is compatible with USB-C charging and is not experiencing an internal issue.
- Try using a different USB-C port on your charger or device, if available.
- Test the cable with another known working device to isolate if the issue is with the cable or the device/charger.
- Data Transfer Not Working:
- Confirm that both connected devices support data transfer via USB-C.
- Ensure the cable is properly connected to both devices.
- Check your device settings to ensure data transfer mode is enabled (e.g., "File Transfer" on Android phones).
- Restart both connected devices.
- Important: This cable supports USB 2.0 data transfer speeds. It does not support video output or display mirroring. If you require these functions, you will need a different type of USB-C cable (e.g., USB-C to DisplayPort, Thunderbolt 3/4).
