3-metre 12 V DC power extension

This 3-metre cable extends a 12 V DC supply using 5.5 mm by 2.1 mm barrel connectors. It is intended for CCTV cameras and similar low-voltage devices that need extra reach between the power source and the unit. The plug-and-play design requires no tools or configuration.

Passive cable with no active cooling

The extension draws no power of its own and generates no heat or noise during normal operation. Voltage drop over the 3-metre length is minimal for typical camera loads. No fan, radiator or external power supply is involved.

Questions about this item

How do I connect the 5.5 mm by 2.1 mm plug to my 12 V CCTV camera without reversing polarity?

Match the centre pin to the camera's positive terminal and the outer sleeve to negative; the barrel jack only fits one way, so push it straight in until it clicks.

Will the copper conductors inside the 3 m length need replacement after a few years of continuous 12 V use?

The solid-core copper is rated for continuous 12 V loads; inspect the jacket annually for cracks, but the conductors themselves do not wear out under normal indoor CCTV operation.
