Alligator Clip to DC 5.5×2.1mm Power Plug Adapter Cable — 25cm Test Lead
Need a quick and reliable way to connect battery terminals or bare wire leads to a standard DC barrel connector? This compact 25cm test lead adapter bridges the gap between 2 alligator (crocodile) clips and a DC 5.5×2.1mm male or female power plug — the most common barrel connector size used in electronics, LED strips, CCTV cameras, routers, and DIY power projects.
Key Features
- Dual Alligator Clips: Two heavy-duty crocodile clips grip wire leads, battery terminals, or bench power supply posts firmly for a stable connection.
- Standard DC 5.5×2.1mm Barrel Connector: Compatible with the vast majority of consumer electronics, security cameras, LED drivers, Arduino/Raspberry Pi power supplies, and more.
- 25cm (≈10 inch) PVC Cable: Flexible, durable PVC insulation keeps the cable tidy while providing enough reach for workbench and field testing.
- Male & Female Option: Available in both male and female DC plug variants — choose the one that matches your device's power input or output.
- No High-Concern Chemicals: Built with materials confirmed free of high-concern chemicals, making it safe for regular workshop use.
- Portable & Lightweight: Slips easily into a tool bag, electronics kit, or carry case for on-the-go testing and prototyping.

Frequently Asked Questions
Q: What devices is the DC 5.5×2.1mm connector compatible with?
A: The DC 5.5×2.1mm barrel connector is the most widely used standard size in consumer electronics. It is compatible with CCTV cameras, LED drivers, routers, Arduino and Raspberry Pi power adapters, small appliances, and most 12V DC bench power supplies.
Q: What is the difference between the male and female DC plug versions?
A: The male version has a protruding pin that plugs into a female DC socket on a device (e.g., powering a camera). The female version accepts a male DC plug from a power supply, useful when you need to connect a power adapter output to a circuit via alligator clips. Choose the variant that matches your application.
Q: Can this cable handle 12V DC power supplies?
A: Yes, the adapter is designed for standard low-voltage DC applications including 5V, 9V, and 12V systems commonly used in electronics prototyping and testing. Always verify the current rating does not exceed the cable's capacity for your specific setup.
Q: Is the alligator clip to DC adapter safe to use on a workbench?
A: Yes. The cable uses PVC insulation and contains no high-concern chemicals. Always ensure polarity is correctly matched (red clip = positive, black clip = negative) before connecting to avoid short circuits.
