Fancasee US-CAB-179 DC Power Extension Cord

The Fancasee US-CAB-179 is a 5.5mm x 2.1mm DC power extension cord designed to extend the reach of power adapters for low-voltage devices. It suits installers and DIY users who need extra length for surveillance IP cameras, CCTV security cameras, DVRs, LED strips, routers, or invoice printers.

Plug-and-Play Installation with 5.5mm x 2.1mm Jacks

The cable features a male-to-female jack configuration that connects directly without tools or drivers. The 5.5mm outer diameter and 2.1mm inner diameter must match the device port exactly; a mismatched barrel size is the most common reason the connection fails or power does not pass through.

Ideal for Fixed Low-Voltage Setups.

This extension suits permanent installations where a 3 ft black cable bridges the gap between a power supply and a compatible DC jack. Buyers who need a different barrel size, longer reach, or higher current capacity than the pure copper conductors provide should look at other cable specifications.
