SIOCEN 4336304934 2-Pack DC Power Extension Cord
This two-pack provides a pair of three-foot cables that extend the reach of any device using a 5.5mm by 2.1mm barrel connector. Each cord carries a male plug on one end and a matching female jack on the other, allowing a straight-through connection between a power supply and the equipment. The cables are built with copper conductors and carry a UL listing for safety compliance. They are suited for installers and hobbyists who need a little extra length for CCTV cameras, LED strips or similar 12-volt gear.
Capacity and headroom: 12 V DC over 3 ft
Rated for 12 volts DC, the cords also accept supplies from 5 V up to 36 V as long as the connector dimensions match. The pure copper core keeps resistance low over the one-metre run, so voltage drop stays minimal for typical low-current cameras, LED lighting, routers or external drives. The fixed three-foot length cannot be shortened, and daisy-chaining multiple cords adds connector resistance; runs significantly longer than a few metres should use a thicker gauge or a higher-voltage distribution scheme instead.
Upgrade path: replaces short fixed tails
The set replaces the short, captive cable that ships with many plug-in power supplies, letting the brick sit at the socket while the device mounts up to three feet away. It is worth the switch when the stock lead is too short to reach a ceiling-mounted camera, an under-cabinet LED strip or a router placed behind furniture. It will not help if the equipment uses a different barrel size, a locking connector or a proprietary DC jack, and it does not add Power-over-Ethernet or any smart negotiation — it is a passive copper extension only.

Questions about this item
Will the 5.5 mm by 2.1 mm connectors on this cord fit the barrel plug on my existing 12 V CCTV camera power supply?
Yes — the male and female barrels are both 5.5 mm outer and 2.1 mm inner diameter, the standard size used on most 12 V CCTV camera adapters, so they mate directly with that equipment.
How can I confirm the extension is delivering power correctly once I’ve connected it between the supply and the camera?
The camera should power up and operate normally; if the LED indicator on the camera lights and the video feed appears, the cord is passing the 12 V DC current as intended.
What exactly comes in the package and is any additional hardware required?
The box contains two 3 ft (1 m) copper-core DC extension cords with 5.5 mm × 2.1 mm male-to-female barrels; no extra connectors or tools are needed for typical CCTV or LED strip installations.
