4. Setup
- Verify Device Requirements: Before connecting, confirm that your electronic device requires a 12V DC input and draws no more than 5A (60W). Check your device's specifications or original power adapter.
- Connect DC Plug: Insert the DC output plug (5.5x2.5mm / 5.5x2.1mm compatible) of the Facmogu adapter into the DC input port of your electronic device. Ensure a firm connection.
- Connect AC Plug: Plug the AC input cord of the adapter into a standard AC 100-240V wall outlet.
- Power On: Once both connections are secure, power on your electronic device. The adapter's indicator light (if present) should illuminate, confirming power delivery.
5. Operating Instructions
Operating the Facmogu power adapter is straightforward once properly set up:
- Ensure all connections are secure before powering on your device.
- The adapter is designed for continuous operation within its specified limits.
- If your device has an on/off switch, use it to control power to the device.
- To disconnect power, first turn off your electronic device, then unplug the AC adapter from the wall outlet.
6. Maintenance
Proper maintenance ensures the longevity and safe operation of your power adapter:
- Cleaning: Disconnect the adapter from power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the adapter in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cables.
- Cable Inspection: Periodically check the power cords and connectors for any signs of wear, cuts, or damage. If any damage is found, discontinue use immediately and replace the adapter.
- Ventilation: Ensure the adapter's ventilation slots remain clear of dust and debris.
7. Troubleshooting
If you encounter issues with your Facmogu power adapter, refer to the following common troubleshooting steps:
No Power to Device:
- Check Connections: Ensure both the DC plug and AC plug are securely connected.
- Verify Outlet: Test the wall outlet with another device to confirm it is functioning.
- Device Compatibility: Double-check that your device's voltage and current requirements match the adapter's specifications (12V, max 5A, max 60W).
- Adapter Indicator: If the adapter has an indicator light, check if it is on. If not, the adapter may not be receiving power or could be faulty.
Unstable Power or Device Malfunction:
- Overload: Ensure your device's current draw does not exceed 5A. If it does, the adapter's over-current protection may be activating, causing intermittent power.
- Cable Damage: Inspect the power cords for any visible damage. Damaged cables can lead to unstable power delivery.
- Overheating: If the adapter feels excessively hot, disconnect it immediately. Ensure it has proper ventilation and is not covered. Overheating can trigger over-temperature protection.
