Setup Instructions
- Verify Compatibility: Ensure your device and its power adapter require a 12V DC power supply and have 2.1mm x 5.5mm DC connectors. Incompatible connectors or voltage can damage your equipment.
- Disconnect Power: Before connecting the extension cable, ensure the power adapter is unplugged from the wall outlet to prevent electrical hazards.

Operating Instructions
Once properly connected, the CHORTAU EC-10 Power Extension Cable operates passively to deliver power to your device. No user interaction is required for its operation. Ensure the cable is routed safely to avoid tripping hazards or damage.
Maintenance
- Regular Inspection: Periodically inspect the cable for any signs of wear, cuts, kinks, or damage to the insulation.
- Environmental Protection: If used outdoors, ensure connectors are protected from direct exposure to wet weather conditions to prevent corrosion and short circuits. While the cable itself is robust, the connection points are vulnerable to moisture.
- Cleaning: Keep the cable and connectors clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Storage: When not in use, coil the cable neatly without sharp bends and store it in a dry place.
Troubleshooting
No Power to Device
- Check Connections: Ensure both ends of the extension cable are securely plugged into the power adapter and the device.
- Verify Power Adapter: Confirm that the original power adapter is functioning correctly by testing it directly with the device (without the extension cable) if possible.
- Check Power Outlet: Ensure the wall outlet is supplying power. Test with another appliance.
- Inspect Cable for Damage: Look for any visible damage to the extension cable. A damaged cable may prevent power transmission.
- Compatibility Check: Double-check that the voltage (12V DC) and connector dimensions (2.1mm x 5.5mm) are correct for your device.
