Simplify your custom power builds with the Professional DC Pigtail. This 5.5mm x 2.1mm DC "Barrel Pig" features a high-conductivity male plug on one end and pre-stripped, color-coded wires on the other. Designed for versatility and ease of installation, it provides a secure and reliable way to connect any bare-wire power source to standard DC-powered devices.
Universal 2.1mm Compatibility: Fits the industry-standard 5.5mm x 2.1mm DC ports found on the vast majority of routers, cameras, and LED controllers.
Pre-Stripped & Tinned Ends: The internal copper cores come pre-exposed and tinned with solder, making it incredibly easy to solder to a board or join with wire connectors.
Polarity Made Easy: Features standard Red (Positive) and Black (Negative) color-coding to ensure you never cross your wires during installation.
Durable Molded Strain Relief: The plug head is over-molded to protect the internal solder points from being pulled or damaged during use.
CCTV Installations: The standard method for hard-wiring analog or IP security cameras directly to a central power supply box.
DIY Electronics: Perfect for makers using battery packs or custom power circuits to run 12V micro-controllers and sensors.
LED Projects: Use it to connect custom LED strip segments to a standard 12V wall adapter or dimmer.
Adapter Repairs: A quick and professional fix for power adapters where the original cable has frayed or snapped at the tip.
Standard 5.5mm x 2.1mm Male Plug: Precision-engineered for a snug, "no-flicker" electrical connection.
High-Purity Copper Cores: Multi-strand copper ensures flexibility and excellent conductivity for 12V and 24V applications.
Insulated PVC Jacket: A rugged, flame-retardant outer casing that is easy to route through tight spaces.
Standard 25cm-30cm Length: Provides enough slack for a clean connection without excessive wire clutter.
