2.1mm DC Power Solder End Connection For CCTV Cable - Kenable

It refers to a DC power connector where the inner pin has a diameter of 2.1mm and the outer barrel has a diameter of 5.5mm. The 'solder end' indicates that you need to solder wires to it to create a connection, rather than using a plug-in type.

No, it is specifically for adapters and devices requiring a 5.5mm outer diameter and 2.1mm inner pin. Always check your device's specifications or the original adapter's plug size.

The suitability for high power depends on the gauge of the wire used and the quality of the solder joint. Ensure the wire gauge is appropriate for the current draw of the device. The connector itself is typically rated for standard DC power applications.

Yes, you will need a soldering iron, solder, wire strippers, and potentially a small screwdriver to tighten the strain relief cover.

RoHS (Restriction of Hazardous Substances) compliance means the product meets certain standards restricting the use of specific hazardous materials in its manufacture.

Ensure wires are clean and stripped appropriately. Heat the terminal and the wire simultaneously with the soldering iron, then apply solder to the heated junction. The solder should flow smoothly. Avoid 'cold' solder joints, which appear dull and lumpy.

Verify solder connections are secure and correctly wired (positive to pin, negative to barrel). Check the power source and ensure it is functioning correctly. Confirm the device requires a 5.5mm x 2.1mm DC plug.

Inspect solder joints for cold joints or poor adhesion. Ensure the wires are firmly attached. Check the strain relief cover is properly secured to prevent movement at the solder points.

The connector has specific dimensions (5.5mm outer, 2.1mm inner). If it does not fit, your device likely requires a different sized DC plug. Do not force the connection.
