  • Black plastic housing with strain relief protects the connection
  • Light 25 g set adds negligible weight to kit

5.5 mm × 2.1 mm DC power coupler set

This pack contains eight straight blade plug couplers with a 5.5 mm outer diameter and 2.1 mm inner pin. Each unit joins two female DC connectors inline for camera or low-voltage device wiring. The plastic housing provides strain relief on every connection. Net weight for the full set is 25 g.

Check your existing power leads

Verify that your current cables use the same 5.5 mm by 2.1 mm barrel dimensions before ordering. Confirm both ends you intend to join are male plugs so the female coupler fits correctly. Ensure the voltage and current ratings of your supply match the devices you are connecting.

Suits installers needing multiple inline joins

Ideal for CCTV installers or hobbyists linking several cameras to one power source. Not suited for buyers who need a male-to-female adapter or a different barrel size. Builders requiring waterproof or locking connectors should look at other products.

Questions about this item

What comes in the 8-piece pack and do I need any extra parts to use them?

The pack contains eight 5.5mm x 2.1mm female DC inline plug couplers with plastic housing and strain relief. No battery is included and no extra parts are required for basic connection.

The listing shows one size — how do I know this 5.5mm x 2.1mm version fits my device?

This coupler accepts a standard 5.5mm outer diameter and 2.1mm inner diameter male barrel plug. Check your power supply or camera connector for those exact dimensions before ordering.

What does the 25g net weight tell me about how the coupler performs once installed?

At 25g for eight pieces the couplers are lightweight, adding minimal bulk to a camera rig or cable run while the strain relief helps protect the solder joints during movement.
