  • Product typePower
  • Converts 5.5×2.1 mm plug to 3.0×1.1 mm for device compatibility
  • 17 cm cable keeps power bricks close to the socket
  • Female 5.5×2.1 mm input accepts standard barrel connectors

  • Ready-to-use adapter eliminates the need for soldering or splicing

DC Converter Cable 17cm

This 17cm adapter cable converts a 5.5mm by 2.1mm female barrel jack into a 3.0mm by 1.1mm male plug with centre pin. It suits users who need to power a device with the smaller connector from a supply fitted with the larger tip.

Passive Adapter No Heat Noise

The cable is a passive connector with no active components, so it generates no heat and produces no audible noise during normal use. Power draw is limited only by the attached supply and device.

Straight Barrel Connectors 17cm

Both ends use straight barrel plugs, keeping the cable compact for tight routing behind equipment. The 17cm length gives enough reach for desk or rack setups without excess slack. Verify the 5.5mm input and 3.0mm output dimensions match your gear before connecting.

Questions about this item

How do I connect the 5.5x2.1mm female input to my power supply without damaging the centre pin?

Align the centre pin of your supply's 5.5x2.1mm plug with the female socket, push straight in until it seats fully, and avoid side force that can bend the inner contact.

Will the 3.0x1.1mm male output need periodic replacement under normal use?

The gold-plated pins resist oxidation; replacement is only needed if the barrel loosens or the cable sheath shows cracking after extended flexing.

What practical limit appears first when the 17cm cable runs at its rated load for long periods?

The thin 17cm conductors warm up before the connectors do, so sustained maximum current is limited by cable temperature rise rather than contact resistance.
