Pack of five 2.1mm x 5.5mm DC female connectors, 50mm long, for standard power devices

  • TypeHI - Power Plugs & Connectors

  • Pack of five female connectors for multiple repairs
  • 1 mm centre pin fits common barrel jacks
  • 5 mm outer diameter matches typical power ports
  • Compact 50 mm length suits tight installations

Five-piece DC female connector pack

This set contains five straight-blade DC female plugs sized at 2.1mm inner diameter, 5.5mm outer diameter and 14mm barrel length. They serve as direct replacements for worn or damaged power-supply connectors on a wide range of standard DC devices. Each plug measures approximately 50mm total length and weighs about 10g. The black and silver-tone finish resists corrosion in everyday use.

Sustained-load behaviour

The connectors maintain a secure, low-resistance contact during continuous power delivery without overheating or loosening. Their solid metal barrels and tight tolerances prevent intermittent signals that can appear after repeated mating cycles. The pack of five lets you refresh multiple units or keep spares for field repairs. No active cooling or derating is required for typical DC power applications.

Pre-order checklist

Verify that your equipment uses a 2.1mm by 5.5mm centre-positive barrel jack with a 14mm insertion depth. Confirm the existing plug housing can accommodate a 50mm overall connector length. Ensure the wire gauge you intend to terminate fits the internal solder cups. These plugs are not suited for high-voltage AC mains or proprietary locking connectors.

Questions about this item

Will the 2.1mm x 5.5mm barrel draw much power or get warm during all-day use?

These are passive connectors with no active electronics, so they add no measurable heat or power draw themselves.

What cable or wire gauge do I need to already have for the 50mm long plug to work?

You will need a two-conductor cable that fits the 2.1mm centre pin and 5.5mm outer sleeve; the plug accepts standard solder or crimp termination.

Can I keep my existing 5.5mm x 2.1mm power supply and just swap the old jack for one of these?

Yes, the 5.5mm outer diameter and 2.1mm inner pin match the common barrel size, so it fits most standard DC devices using that spec.
