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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
