  • FeaturesThis 10 feet power extension cord is made by Wefomey and fea
  • Extends power reach with two 10ft cables
  • Pure copper conductors carry up to 3A at 12V
  • 5mm x 2.1mm barrel fits many CCTV and LED devices

  • Plug-and-play design cascades for 20ft or longer runs

Two cables, ten feet each

This pack supplies two 10-foot DC extension cords with 5.5mm by 2.1mm barrel connectors on both ends. They are intended for users who need to extend the reach of a 12-volt power adapter for security cameras, LED strips, CCTV equipment or similar low-voltage devices.

Pure copper conductors, UL listed

Each cable uses pure copper wire for lower resistivity and carries a UL listing. The male and female plugs share the same 5.5mm outer and 2.1mm inner diameter, allowing multiple cords to be cascaded for longer runs when a single 10-foot length is insufficient.

Check plug size and voltage before ordering

This cord only fits equipment that uses a 5.5mm by 2.1mm barrel jack; other sizes will not connect. The maximum supported current is 3 amps at 24 volts or lower, so verify your adapter’s output rating and measure the existing plug to confirm compatibility.

Questions about this item

What does the 5.5mm x 2.1mm barrel connector limit in practice?

The 5.5mm x 2.1mm barrel connector fits only devices with that exact plug size and caps the maximum load current at 3A for 24V or lower DC equipment.

What physical clearance does the 10ft cable need for routing?

Each 10ft cable requires enough slack to run from the power adapter to the device; two cables can be cascaded for a 20ft reach if a single length is insufficient.

How do I install the extension cord and what step is often missed?

Plug the male 5.5mm x 2.1mm end into the power adapter and the female end into the device; the step often missed is verifying the adapter plug measures exactly 5.5mm outer and 2.1mm inner diameter before connecting.
