Two 20 ft cables for DC devices

This pack contains two power extension cords, each 20 ft long, with 2.1 mm by 5.5 mm barrel connectors on both ends. They are designed for 12 V DC equipment such as CCTV cameras, LED strips, DVRs, monitors and similar low-voltage hardware. The flat profile lets the cable slip through narrow gaps without drilling. Buyers who need a different connector size or a longer single run cannot use this kit.

Plug-and-play with polarity care

Installation is straightforward: connect the male barrel plug to the device and the female jack to the existing power cable. The flat cable routes easily through door frames or window seals. The only common issue is reversing polarity, so confirm the centre-positive wiring of your hardware before powering on. No tools or soldering are required for a secure fit.

3 A current ceiling on 5.5 mm barrel

The 5.5 mm barrel interface limits the maximum load current to 3 A across the supported voltage range of 5 V to 24 V. Runs of 20 ft on thin flat conductors add resistance, so voltage drop becomes noticeable at higher currents. Devices drawing more than 3 A or requiring a locking connector are outside the safe operating envelope of this extension.

Questions about this item

How can I verify the 2.1 mm x 5.5 mm DC extension cord is working after connecting it to my 12 V camera?

Check that the camera powers on and records normally; the flat cable should sit flush through any small gap without signal loss.

What comes in the box and what must I buy separately for the 20 ft extension set?

The pack includes two 20 ft flat cables with 2.1 mm x 5.5 mm male and female ends; you only need a compatible 12 V power supply and the camera itself.

Which version should I choose for a 24 V LED strip that draws under 3 A?

This single 2.1 mm x 5.5 mm variant supports 24 V, 12 V, 9 V, 6 V or 5 V DC loads up to 3 A, so it covers the strip without any other option.
