Two short black adapter cables with 5.5mm female and 3.0mm male DC plugs

SMUGDESK

SMUGDESK 2PCS 5.5×2.1mm to 3.0×1.1mm DC Power Adapter Cord

SKU CH-6FJ7-HZ0GS

Two cables convert 5.5 × 2.1 mm female DC jacks to 3.0 × 1.1 mm male plugs for powering routers, cameras and LED strips

  • Two cables included for spare or alternate use
  • 5×2.1mm female to 3.0×1.1mm male converts power adapter plugs
  • Copper conductors deliver stable current with low voltage drop
  • Compact plug design allows easy plug-and-play installation
  • Works with routers, cameras, LED strips and portable electronics

Two-piece adapter set

This pair of DC power cords converts a 5.5mm x 2.1mm female jack to a 3.0mm x 1.1mm male plug. The set suits technicians and hobbyists who must match legacy power supplies to smaller device ports. Each cable handles DC power only and carries no data signals. Two units are included for spares or parallel installations.

Fixed barrel dimensions

The connector sizes are set at 5.5mm outer diameter with 2.1mm centre pin on the input side and 3.0mm outer diameter with 1.1mm centre pin on the output side. No other barrel sizes or pin configurations are supported by this cable. Polarity is not altered by the adapter, so the source and load must already share the same centre-positive or centre-negative arrangement. Current capacity is limited by the wire gauge and contact area of these specific plugs.

Copper conductors and plug-and-play use

Internal copper wiring keeps voltage drop low during DC power delivery. The compact moulded plugs allow direct insertion without soldering or tools, making them practical for field swaps on routers, cameras, LED strips and development boards. The short cable length keeps the connection tidy inside enclosures. Users must verify that the device voltage and polarity match the supply before connecting.

Questions about this item

Should I pick the 5.5×2.1mm female to 3.0×1.1mm male cable or the reverse?

This pack only provides the 5.5×2.1mm female to 3.0×1.1mm male orientation, so you can power a 3.0×1.1mm device from a 5.5×2.1mm adapter.

Will this cord handle the current my router draws without voltage drop?

The copper conductors are designed for stable DC power delivery and low voltage drop on typical small devices such as routers and cameras.

Does the 5.5×2.1mm to 3.0×1.1mm barrel standard limit the power I can deliver?

The connector pair simply passes DC power; the actual limit is set by your power adapter and the device's own rating, not by the cable itself.
