Product Description
The DC 2.1mm Male Power Plug Screw Terminal Connector (MALE-POWER-SCREW-GR) lets you fit your own power plug onto a cable without soldering. You strip the cable ends, drop the two conductors into the screw terminals, and tighten — done in a couple of minutes.
It's a male plug, meaning it's the end that pushes into a socket — matching the standard 5.5mm x 2.1mm DC power inputs found on most CCTV cameras, DVRs, NVRs, and 12V LED lighting gear. If your existing lead is too short, damaged, or you're wiring a fresh run into a junction box, this is the part that finishes the job.
Why screw terminal instead of solder
- No soldering iron or skill needed on site — useful when you're up a ladder or working inside a cramped enclosure.
- Faster to swap out if a cable gets damaged later; just loosen the screws and re-terminate.
- Positive and negative conductors are separated internally, so getting polarity right at the terminals matters.
Before you buy
- Check the device's power socket is genuinely 5.5mm x 2.1mm — some cameras use slightly different barrel sizes.
- If you're running a long cable to a camera, remember thin or lengthy cable runs can cause voltage drop, which shows up as flickering or dropout on infrared night vision — use adequately rated cable alongside this connector.
- Its compact shell is built to sit inside junction boxes or distribution enclosures, not out in the open.

Frequently Asked Questions
What socket size does this plug fit?
It's built to the standard 5.5mm outer diameter, 2.1mm inner diameter DC socket found on most CCTV cameras and DVR/NVR power inputs.
Do I need to solder the wires in?
No — it uses a screw terminal, so you strip the cable ends and tighten them into place without any soldering.
Can this cause flickering or night-vision dropout if I use a long cable run?
The connector itself won't cause that, but a long or thin cable run can create voltage drop that leads to IR flickering, so use suitably rated cable.
Is this a male or female connector?
It's the male plug — the end that inserts into a device's power socket.
