Unique-Bargains DC Power Adapter Kit 10pcs 5.5 x 2.1mm Jack Converter Barrel Connector Set

SKU CH-GQG2-KMY43

Set of ten 5.5 x 2.1 mm barrel connectors for replacing damaged laptop power plugs

  • 10-piece kit covers multiple replacement needs
  • 5 mm outer and 2.1 mm inner diameter fits common laptop barrels
  • Nickel-plated contacts resist corrosion for reliable power delivery
  • Universal design works with external supplies and on-board transformers
  • Direct swap for damaged connectors without soldering

Universal Laptop Power Connector Kit

This kit supplies ten barrel adapters with a 5.5 by 2.1 millimetre centre-positive jack. The nickel-plated contacts resist corrosion and maintain reliable conductivity for external power supplies or on-board transformers. It is aimed at technicians and owners who need a quick replacement for a worn or damaged connector.

Direct Replacement for Failed Barrel Plugs

The set replaces a single broken tip on a laptop charger or device input without rewiring the entire cable. The jump is worth it when the original connector fractures, develops intermittent contact or no longer seats securely. Buyers who need a different inner diameter or a right-angle form factor will not find those variants in this package.

Plug-and-Play Fit for Standard DC Inputs

Each adapter slides into any 5.5 by 2.1 millimetre jack, freeing the user from soldering or crimping during field repairs. The compact barrel adds no strain to the port and leaves surrounding ports unobstructed. Builds that require locking collars, screw terminals or higher current ratings will need a different connector style.

Questions about this item

What barrel connector dimensions does the 5.5 x 2.1mm jack converter set fit?

Each of the 10 pieces in the kit accepts a 5.5 mm outer diameter and 2.1 mm inner diameter barrel plug for direct connection.

How do I install the nickel-plated barrel connectors without soldering?

Strip the cable wires, insert them into the screw terminals on each connector, tighten the screws securely, then snap the housing closed — the step often missed is fully tightening both terminal screws.

When should I replace a connector from this 10-piece adapter kit?

Replace a unit if the nickel plating shows corrosion, the barrel feels loose in the device port, or intermittent power occurs when the cable is moved.
