  • TypeHI - Power Plugs & Connectors
  • 15 connectors per pack for multiple repairs

  • Solder terminals create a secure permanent joint
  • 5 mm cable entry matches standard wire gauges
  • Compact 44 mm length suits tight enclosures

15-Pack 5.5mm x 2.1mm DC Power Plugs

This pack contains fifteen straight blade male DC plug connectors with a 5.5mm outer diameter and 2.1mm inner pin. They are designed for solder-type attachment to a cable, making them suitable for repairing or building custom power supply leads for compatible devices.

Check Cable Diameter and Polarity Before Use

The connectors accept a cable diameter of approximately 4.5mm, so verify your wire insulation fits this size. Ensure the tip-positive or tip-negative polarity matches your equipment, as the plug housing does not enforce a specific wiring standard.

Replaces Damaged or Missing Barrel Jack Connectors

These plugs serve as direct replacements for worn or broken 5.5mm x 2.1mm barrel connectors on existing power cables. The upgrade is worthwhile when the original moulded plug has failed and a solderable, serviceable connector is preferred over a pre-assembled lead.

Questions about this item

What comes in the pack and do I need any extra parts to solder these plugs?

The pack contains 15 black and silver-tone DC plugs, each measuring 44 mm by 10 mm and weighing 24 g total. You will need your own cable up to 4.5 mm diameter and a soldering iron to attach the wires.

Should I choose a different size or is the 5.5 mm by 2.1 mm version the right one for standard DC devices?

This listing only offers the 5.5 mm outer and 2.1 mm inner diameter size, which fits most standard DC power equipment. If your device uses a different barrel size you will need a different connector.

Once soldered, how much space does each straight blade plug take up inside a device chassis?

Each plug is 44 mm long and 10 mm in diameter, so allow roughly 1.7 inches by 0.39 inches of clearance behind the panel for the soldered joint and strain relief.
