Extension Cable Overview
This eForChina DC power extension cable uses a 5.5 x 2.1 mm female-to-male connector to lengthen existing power runs. The three-metre black cable suits CCTV cameras, LED strips, routers or similar low-voltage devices that already use this barrel size. A TPE and PVC jacket protects the conductors while staying flexible for routing.
Ideal Use Cases
Installers who need extra reach between a power supply and a fixed 5.5 x 2.1 mm jack will find the secure fit saves setup time. Buyers whose equipment uses a different barrel diameter or a locking connector should select a cable that matches their specific port.
Connector Specification
The sole compatibility factor is the 5.5 mm outer and 2.1 mm inner pin dimension on both ends. If the device or supply uses any other barrel size the cable will not connect.

Questions about this item
Does the cable come with any extra adapters or must I buy a matching power supply separately?
Only the extension cable itself is supplied; a compatible 5.5 x 2.1 mm DC power source is required and not included
Which of the offered lengths — 1m, 1.5m, 3m, 5m or 10m — should I choose for a typical desk setup?
The 3 m length gives enough reach for most desk layouts without excess cable clutter
What does the 5.5 x 2.1 mm specification mean when I plug the cable into my device?
It matches the standard barrel jack size used by many routers, monitors and small appliances, so the connector fits directly without an adapter
