Setup and Installation
The Smays DC Extension Cord is designed for simple plug-and-play installation. Ensure that the power adapter and the device you intend to connect both use a 3.5mm x 1.35mm DC barrel connector and operate at compatible voltage and current levels.
Connecting the Extension Cord
- Identify Connectors: Locate the male barrel connector on your existing power adapter's cable and the female DC input port on your device.
- Connect Power Adapter: Insert the male end of the Smays extension cord into the female output port of your DC power adapter. Ensure a snug fit.
- Connect Device: Insert the female end of the Smays extension cord into the male DC input port of your electronic device (e.g., Foscam IP camera). Ensure a secure connection.
- Verify Power: Once connected, power on your device and verify that it receives power and functions correctly.

Operation
The Smays DC Extension Cord operates passively by extending the physical reach of your existing DC power connection. Once properly connected, it allows your device to receive power from a greater distance without affecting the voltage or current supplied by the original power adapter. No specific operational steps are required beyond proper connection.
Care and Maintenance
- Storage: When not in use, coil the cord neatly to prevent tangling and kinking. Store in a cool, dry place away from direct sunlight.
- Cleaning: Wipe the cord and connectors with a soft, dry cloth if they become dusty. Do not use liquid cleaners or abrasive materials.
- Handling: Avoid bending the cord sharply, especially near the connectors, as this can damage the internal wiring. Do not pull on the cord to disconnect; always grasp the connector ends.
- Environmental Conditions: While durable, avoid exposing the cord to extreme temperatures, excessive moisture, or corrosive substances.
