Power Connector Specifications

The Unique-Bargains DC power coupler provides a 2.1mm by 5.5mm male-to-female connection for surveillance equipment. It replaces worn or damaged connectors on existing power cables. The unit suits installers and DIY users maintaining security camera systems.

Build Integration

The coupler fits inline between a power supply and a camera without tools or soldering. Its ABS and metal construction adds minimal bulk to the cable run. One piece is included per package, so each connection point requires its own unit.

Sustained Operation

The materials handle continuous current flow typical of always-on surveillance devices. No active cooling is required for the connector itself. It remains a passive component that simply extends or repairs the power path.

Questions about this item

What is the first limit that appears when this 2.1mm x 5.5mm coupler runs continuously?

The small ABS body and thin metal pins can warm up under sustained current, so the connector itself becomes the thermal bottleneck before the cable does.

How much noise, heat or power draw does the coupler add during all-day operation?

It adds no noise and negligible resistance, so heat stays low and power loss is minimal, but the ABS housing will feel warm if the attached supply runs near its maximum rating.

What must I already own for this male-to-female DC coupler to work?

You need a power source with a 2.1mm x 5.5mm female jack and a device with a matching male plug, or the reverse, because the coupler only bridges identical barrel sizes.
