DC 5.5x2.1mm Jack to Dual Alligator Clip Power Cable

A simple, reliable adapter cable that bridges your DC 5.5x2.1mm jack connector to two colour-coded alligator clips. Perfect for electronics hobbyists, makers, and technicians who need a quick and secure power connection for testing, bench work, or small DC-powered projects.

Key Features

Universal DC Connector: Male or Female 5.5mm x 2.1mm DC jack — one of the most common sizes used in power supplies, LED drivers, CCTV cameras, and Arduino/Raspberry Pi setups.
Colour-Coded Clips: Red clip = Positive (+), Black clip = Negative (−) — eliminating guesswork and reducing the chance of reverse-polarity connections.
Middle-Sized Alligator Clips: Sturdy metal construction for a firm, stable grip on terminals, battery leads, or component wires.
Compact 25cm Cable Length: Ideal for desktop and bench-top use without excess cable clutter.
Metal Construction: Durable metal clips and connector housing for lasting performance.

Frequently Asked Questions

Q: What is the DC jack size on this power cable?

A: The connector is a standard 5.5mm outer diameter × 2.1mm inner pin DC jack, available in both male and female versions. This is one of the most widely used sizes in consumer electronics, power supplies, and DIY projects.

Q: What are the alligator clips used for?

A: The alligator clips allow you to quickly attach the cable to battery terminals, component leads, or bare wires without soldering. Red is positive (+) and black is negative (−), making polarity identification straightforward and safe.

Q: How long is the cable?

A: The cable is approximately 25cm (about 10 inches) long, making it compact and well-suited for desktop electronics testing and bench-top work.

Q: Can I use this with an Arduino or Raspberry Pi power supply?

A: Yes. If your power supply uses a 5.5x2.1mm DC barrel jack, this cable lets you connect it directly to your project's power input points via the alligator clips — ideal for prototyping and testing.
