SKU CH-H2H3-TFZQW MPN 2.1

Set of twelve 5.5×2.1 mm DC power jack adapters with 150 mm 18AWG pre-soldered leads rated for 30 V at 10 A

  • TypeAdapters
  • Ready-to-install 12-piece kit with pre-soldered 150 mm leads
  • 10 A continuous rating supports demanding DC devices
  • 18 AWG tin-plated wires simplify soldering and ensure solid joints
  • Threaded 5.5 × 2.1 mm barrels lock securely against vibration
  • Waterproof caps and flame-retardant bodies protect connections in harsh environments

12-Piece DC Power Adapter Kit

This kit supplies twelve 5.5 x 2.1 mm barrel connectors with 150 mm 18AWG leads already soldered in place. Red and black insulation marks polarity for quick identification. Threaded male and female mounts allow secure panel installation. The set is aimed at technicians and hobbyists repairing or building DC power connections.

Repairers needing panel-mount jacks.

The adapters suit projects that require a 5.5 x 2.1 mm interface at up to 30 V DC and 10 A, such as appliance repair, test bench wiring or custom enclosures. Buyers who need AC mains connectors, higher voltage ratings or unsoldered bulk cable should look at other product types. Waterproof caps are included for outdoor or damp environments.

30 V DC 10 A rating defines safe operating limit

Each connector is rated for 30 V DC at 10 A, so the assembly must not exceed that voltage or current. The 18AWG pre-soldered wires and tin-plated ends support this load within the specified range. Exceeding the rating risks overheating and failure.

Questions about this item

How can I confirm the adapter is delivering 30V DC at up to 10A after installation?

Use a multimeter on the red and black 18AWG leads to verify 30V DC polarity and measure current draw under load up to 10A.

What does the 12-piece kit include and what extra items are needed for a complete connection?

The box contains 4 male mount connectors, 4 female mount connectors and 4 male barrel plugs with 150mm pre-soldered wires; no extra parts are required for standard 5.5×2.1 mm DC hookups.

Which version should I choose for a 5.5 mm barrel with a 2.1 mm centre pin?

This model is built specifically for 5.5 mm outer diameter and 2.1 mm inner diameter, rated 30V DC 10A, so it matches that exact interface.
