1. Introduction
This manual provides essential instructions for the safe and effective use of your Digipartspower Car DC Adapter. This adapter is designed to provide 120W DC power from a vehicle's cigarette lighter socket to compatible devices, such as the MotoMaster Eliminator 300A PowerBox. Please read this manual thoroughly before use and retain it for future reference.
2. Safety Information
To ensure safe operation and prevent damage to the adapter or connected devices, observe the following precautions:
- Compatibility Check: Before connecting, verify that the DC output voltage and tip size of this adapter are compatible with your device's requirements. Incorrect voltage or tip size can cause damage.
- Ventilation: When using the adapter for extended periods, ensure adequate ventilation around the unit. Avoid placing it in enclosed spaces or on surfaces that may obstruct airflow.
- Temperature and Humidity: Do not expose the adapter to extreme temperatures, direct sunlight, or high humidity. Keep it away from heat sources.
- Surface Contact: Avoid placing the adapter directly on skin products or other materials that may retain heat or be sensitive to temperature changes during operation.
- DC to DC Only: This product is a DC-to-DC adapter, meaning it converts DC power from one source (vehicle) to another DC output for your device. It is not an AC-to-DC converter.
- Protection Features: The adapter is equipped with Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP) to safeguard both the adapter and your connected devices.
- Immediate Discontinuation: If you notice any abnormal conditions, such as smoke, unusual odors, or excessive heat, immediately disconnect the adapter from both the vehicle and the connected device and contact customer support.

4. Setup and Installation
Follow these steps to properly set up and install your Car DC Adapter:
- Verify Compatibility: Before connecting, confirm that your device (e.g., MotoMaster Eliminator 300A PowerBox) requires a 12V DC input and that the adapter's tip size matches your device's power input port.
- Connect to Device: Insert the adapter's output connector firmly into the DC input port of your electronic device.
- Connect to Vehicle: Insert the cigarette lighter plug end of the adapter into your vehicle's 12V accessory (cigarette lighter) socket. Ensure it is fully seated.

5. Operating Instructions
Once properly connected, the adapter will supply power to your device. No additional controls are present on the adapter itself. The operation is automatic upon connection to a live 12V socket and a compatible device.
- Ensure your vehicle's engine is running or the accessory power is active to provide power to the socket.
- Monitor your device's charging or power indicator to confirm it is receiving power.
- Disconnect the adapter from the vehicle's socket when not in use to prevent draining the vehicle's battery, especially if the socket remains live when the ignition is off.
6. Maintenance
Proper maintenance ensures the longevity and reliable performance of your adapter:
- Cleaning: Use a soft, dry cloth to clean the adapter. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and moisture when not in use.
- Cord Care: Avoid sharp bends or kinks in the power cord. Do not pull on the cord to disconnect the adapter; always grasp the plug.
- Inspection: Periodically inspect the adapter and cord for any signs of damage, such as frayed wires or cracked casing. Do not use if damaged.
7. Troubleshooting
If the adapter is not functioning as expected, consider the following:
- No Power to Device:
- Ensure the adapter is fully inserted into the vehicle's 12V socket.
- Check if the vehicle's 12V socket is receiving power (e.g., by testing with another known working device). Some vehicle sockets only activate with the ignition on.
- Verify that the adapter's output connector is securely plugged into your device.
- Confirm that your device is turned on and its power input port is functional.
- Device Not Charging/Operating Correctly:
- Re-check the compatibility of the adapter's DC output and tip size with your device's specifications.
- Ensure the device itself is not faulty.
- Overheating:
- Disconnect the adapter immediately.
- Ensure adequate ventilation around the adapter.
- Verify that the connected device's power requirements do not exceed the adapter's 120W capacity.
If issues persist after performing these checks, please contact customer support.
