A 1.5-metre (5 ft) extension cable with a 5.5 / 2.1 mm barrel jack (female) on one end and a barrel plug (male) on the other. Heavy-duty 24 AWG wires handle up to 5 A, making it suitable for powering LED strips, Arduino boards, and other current-hungry projects at a distance.
This cable also doubles as a source of two separate barrel cables — cut it in half to get a plug cable and a jack cable for custom power wiring to breadboards, battery packs, or PCBs without soldering in a bulky connector.
Key Features
- 5.5 / 2.1 mm Connectors – Standard barrel jack (female) and plug (male)
- 1.5 m (5 ft) Length – Generous reach for bench and installation use
- 24 AWG Wire – Rated for up to 5 A
- 3-in-1 Design – Use as an extension cable, or cut in half for two separate barrel cables
Ideal For
- Extending the reach of DC wall adapters
- Powering devices mounted away from the power source
- Custom power cable assemblies (cut in half for a plug and jack cable)
- Breadboard and prototyping power connections
Package Contents
- 1× 2.1 mm Female/Male Barrel Jack Extension Cable (1.5 m)
Jargon buster
Plain-language definitions for the technical terms used above.
- AWG
- American Wire Gauge is a numbering system for wire thickness, where a lower number means a thicker wire. The AWG rating matters because thicker wire can usually carry more current with less voltage drop and heating.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
