Unique-Bargains 5.5mm x 2.1mm Solder Female DC Power Plug 4pcs

SKU CH-WECH-V8NWV

Four solder-type female DC power plugs with 5.5mm x 2.1mm dimensions for inline camera connections

  • Pack of four plugs covers multiple connections
  • 5 mm by 2.1 mm size fits standard DC jacks
  • Solder terminals give a permanent low-resistance joint
  • Female inline format extends or repairs power leads
  • Light 14 g total weight adds negligible bulk

5.5 mm × 2.1 mm DC Power Plug Pack

This pack contains four straight-blade female DC power plugs with a 5.5 mm outer and 2.1 mm inner diameter. They suit hobbyists, repair technicians or installers who need to terminate bare wires onto a standard barrel connector for cameras or similar low-voltage devices. Each plug uses a solder-type connection and a black-and-silver plastic housing with strain relief.

Replacing Damaged or Missing Barrel Connectors

The plugs replace worn, broken or lost DC jacks on power leads without requiring a full cable swap. The jump is worth it when the existing wire is sound but the connector has failed, letting you restore power quickly with basic soldering tools. They also serve new custom cables where a pre-moulded jack is unavailable or the wrong polarity.

Inline Coupler for Camera and Low-Voltage Builds

The inline female body accepts a matching male barrel plug, so the assembly sits between a power source and the device. You need a soldering iron, solder and heat-shrink or tape to finish each termination. The compact 41 mm length keeps the joint tidy inside enclosures or along cable runs, while the strain relief protects the solder joints from flexing.

Questions about this item

What cable diameter fits the 5.5mm x 2.1mm inline jack?

The plug accepts a 5.5 mm outer diameter and 2.1 mm inner diameter centre pin, matching standard DC power cables for cameras and similar devices.

How do I solder the terminals without melting the plastic housing?

Tin the wire ends first, apply heat briefly to each terminal, and let the joint cool before stressing the strain-relief collar to avoid softening the body.

When should I replace the four plugs in the pack?

Replace a plug if the centre pin becomes loose, the barrel shows cracks, or the solder joints turn intermittent after repeated flexing.
