2. Safety Information
To ensure safe operation and prevent damage to the power supply or connected devices, please observe the following safety guidelines:
- Indoor Use Only: This power supply is designed for indoor use. Do not expose it to water, moisture, or high humidity.
- Voltage and Amperage Matching: Ensure your device requires 12V DC power and its current draw does not exceed 12A (144W). Connecting devices with higher power requirements will damage the adapter.
- Correct Polarity: Always verify the polarity of your device matches the adapter's output (internal positive "+", outside negative "-"). Incorrect polarity can cause severe damage.
- Avoid Overload: Do not connect devices that collectively draw more than 12A or 144W. It is recommended to operate at 80% or less of the maximum load (e.g., for a 144W adapter, power devices up to 115W).
- Ventilation: Ensure adequate ventilation around the power supply to prevent overheating. Do not cover the adapter during operation.
- Cable Integrity: Regularly inspect the power cord for any signs of damage. Do not use if the cord is frayed or damaged.
- Disconnect When Not in Use: Unplug the power supply from the wall outlet when not in use for extended periods.

4. Setup Instructions
Follow these steps to set up your ALITOVE 12V DC Power Supply:
- Verify Device Compatibility: Before connecting, confirm that your electronic device requires a 12V DC input and its power consumption (amperage/wattage) is within the 12A/144W limit of this adapter.
- Check DC Connector: Ensure your device's DC input port is compatible with the 5.5mm x 2.5mm or 5.5mm x 2.1mm barrel connector of the adapter.
- Confirm Polarity: Verify that your device's required polarity matches the adapter's (internal positive "+", outside negative "-").
- Connect DC Plug: Insert the DC output plug of the adapter firmly into your device's DC input port.
- Connect AC Power Cord: Plug the AC power cord into the adapter's AC input socket.
- Connect to Wall Outlet: Insert the AC power cord's plug into a standard 100-240V AC wall outlet.
- Power On: The adapter typically has an indicator light that will illuminate when power is supplied. Your device should now receive power.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your power supply:
- Cleaning: Disconnect the power supply from the wall outlet and your device before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a cool, dry place away from direct sunlight, moisture, and extreme temperatures when not in use.
- Cable Care: Avoid sharp bends, kinks, or excessive pulling on the cables. Ensure cables are not pinched by furniture or heavy objects.
- Environmental Conditions: This adapter is designed for indoor use. Protect it from dust, dirt, and corrosive environments.

7. Troubleshooting
If you encounter issues with your ALITOVE power supply, refer to the following common troubleshooting steps:
- No Power Indicator Light:
- Ensure the AC power cord is securely plugged into both the adapter and the wall outlet.
- Test the wall outlet with another device to confirm it is functional.
- Check for any visible damage to the power cord or adapter.
- Device Not Receiving Power:
- Verify the DC output plug is fully inserted into your device's input port.
- Confirm that your device's voltage and current requirements match the adapter's specifications (12V, max 12A/144W).
- Check the polarity of the DC connection. Incorrect polarity can prevent operation or damage the device.
- Ensure the device is not drawing more than 12A/144W, which could trigger the adapter's overload protection.
- Adapter Overheating:
- Ensure the adapter has adequate ventilation and is not covered.
- Reduce the load on the adapter by disconnecting some devices if multiple are connected, or by using a lower power-consuming device.
- If overheating persists at normal loads, discontinue use and contact support.
If these steps do not resolve the issue, please refer to the Warranty & Support section for further assistance.
