Product Purpose

This 10 metre DC power extension cord carries 12 volt supply at up to 3 amps through a 22AWG cable. It is intended for installers and DIY users who need to reach low‑voltage devices such as CCTV cameras or monitors from a distant power adapter. The UL listed construction suits indoor and outdoor runs where a standard adapter lead falls short.

Connector Fit

The cord terminates in a 5.5 mm by 2.5 mm male plug and matching female jack, so it only extends equipment already using that exact barrel size. Adapters with different inner or outer diameters will not connect, and the cable cannot be used with smaller digital devices that employ proprietary plugs. Measuring the existing connector before purchase avoids mismatches.

Voltage And Current Limits

The wire is rated for DC voltages up to 36 volts and a maximum continuous load of 3 amps. Loads above that rating or AC mains voltages will overheat the 22AWG conductors and void the safety certification. Long runs at the upper current limit will also introduce measurable voltage drop at the far end.

Questions about this item

Will the 22 AWG wire or the 5.5 mm x 2.5 mm connectors need replacement after continuous 12 V use?

The 22 AWG copper conductors and barrel connectors are rated for the full 3 A load at 12 V, so no scheduled replacement is required under normal indoor operation.

What stops me from drawing more than 3 A through this 10 m extension?

The cable is specified for a maximum continuous load of 3 A; exceeding that will cause voltage drop and heating that the 22 AWG conductors are not designed to handle.

Does the white jacket or the UL-listed construction get hot when the cord runs a camera all day at 3 A?

At the rated 3 A the 22 AWG wires stay within safe temperature limits; the jacket remains warm but not hot during continuous 12 V camera operation.
