Converter cable for 5.5x2.1mm to 3.0x1.1mm tips

This DC converter cable adapts a 5.5mm by 2.1mm female barrel jack to a 3.0mm by 1.1mm male plug with a centre pin. It lets you power a device that uses the smaller connector from a supply fitted with the larger one. The cable measures 17cm in total length and is sold as a pair.

Users matching these exact tip sizes and polarity

It suits anyone whose AC adapter has a 5.5x2.1mm output and whose hardware requires a 3.0x1.1mm input with a centre pin. Builders needing a different barrel diameter, a different pin arrangement, or a longer reach should look at something else.

Tip geometry decides compatibility

The single specification that determines fit is the connector pairing: a 5.5mm by 2.1mm female input and a 3.0mm by 1.1mm male output with pin. Verify both dimensions and the pin presence on your equipment before purchasing.

Questions about this item

How can I confirm the 17 cm cable is converting power correctly after connecting it?

Plug the 5.5 mm x 2.1 mm female end into your power supply and the 3.0 mm x 1.1 mm male end into the device; if the device powers on and runs normally the converter is working.

What comes in the package and is anything else required?

The pack contains two 17 cm converter cables with a 5.5 mm x 2.1 mm female input and a 3.0 mm x 1.1 mm male output; no extra parts are needed if your adapter and device match those tip sizes.

Which version should I choose if my power supply has a 5.5 mm x 2.1 mm tip and my device needs a 3.0 mm x 1.1 mm tip?

This single version converts exactly from a 5.5 mm x 2.1 mm female connector to a 3.0 mm x 1.1 mm male connector, so it matches that requirement directly.
