5-pack DC extension leads 30 cm

This set contains five new power extension cords each 30 cm long with a 5.5 mm by 2.1 mm DC barrel connector. They are intended for builders and technicians who need short extra reach when wiring low-voltage devices such as LED lighting or CCTV cameras. The cables use a pure copper core rated at 4 A and have a 2 mm outer diameter.

Suitable for low-current DC devices.

The cords suit installations where a 4 A rating at the given connector size is sufficient. They are not appropriate for equipment that draws more current than 4 A or that requires a different barrel diameter or pin size. Users needing longer runs or alternative connector types should look at other options.

5.5 mm by 2.1 mm barrel interface decides fit

The single specification that determines compatibility is the 5.5 mm outer diameter and 2.1 mm inner pin of the DC plug. Verify that the target device uses exactly this interface before purchasing; a mismatched barrel size will prevent a secure connection.

Questions about this item

Will the 5.5 mm by 2.1 mm barrel connector fit my device's power jack?

Measure the jack's inner diameter; this cord uses a 2.1 mm centre pin, so it only fits jacks made for that exact size.

How do I connect the pigtail end without making a loose joint?

Strip each 0.75 mm² conductor, twist the strands, then solder or crimp to your terminals — skipping the twist leaves high resistance.

When should I replace these 30 cm cords if they power LED strips continuously?

Insulate and route away from heat; replace any cord showing cracked 2 mm jacket, discoloured copper or intermittent flicker.
