Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Adapter LED is off, device not powering on. | No power from outlet; loose connection; faulty adapter. | Check if the power outlet is functional by testing with another device. Ensure all connections (AC plug to outlet, DC plug to device) are secure. Try a different outlet. If the issue persists, the adapter may be faulty and require replacement. |
| Device powers on but functions intermittently or incorrectly. | Insufficient power; incompatible adapter; faulty device. | Verify the device's power requirements (voltage and amperage) precisely match the adapter's output (12V, 3A). Ensure the adapter is not overloaded by connecting devices that exceed its wattage. Test with another compatible adapter if available. Consult your device's manual for further troubleshooting. |
| Adapter feels excessively hot during operation. | Overload; poor ventilation; internal fault. | Disconnect the adapter immediately from both the outlet and the device. Ensure the adapter is placed in a well-ventilated area and not covered. Verify the connected device's power draw does not exceed the adapter's capacity. If overheating continues after ensuring proper ventilation and load, discontinue use and replace the adapter. |
