7. Troubleshooting

If you encounter issues with your KFD power adapter, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Device not powering on.	Adapter not plugged in. Incorrect DC tip used. Incorrect polarity. Device requires more power than 24W. Faulty power outlet.	Ensure adapter is securely plugged into a live outlet. Verify the DC tip matches your device's port. Check your device's manual for correct polarity and ensure the adapter's tip matches. Confirm your device's power requirements do not exceed 12V 2A (24W). Test the outlet with another device.
Adapter feels hot.	Normal operation under load. Poor ventilation. Overload.	A slight warmth is normal. Ensure the adapter is in an open area with good airflow. Disconnect if excessively hot and verify device power requirements.
Intermittent power.	Loose connection. Damaged cable/tip.	Check all connections (wall outlet, adapter to tip, tip to device). Inspect the cable and tips for any visible damage. Replace if damaged.
