  • Product typePower
  • Converts 5.5 × 2.1 mm female to 5.5 × 2.5 mm male with pin

  • Simple adapter replaces mismatched tips on DC power supplies

Adapter purpose and target user

This 17 cm DC converter cable changes a 5.5 mm by 2.1 mm female barrel jack into a 5.5 mm by 2.5 mm male plug with centre pin. It suits anyone connecting a power supply that has the larger 2.1 mm inner diameter to a device requiring the smaller 2.5 mm tip.

When this adapter is not the answer

Builders who need to convert the opposite direction, from a 2.5 mm source to a 2.1 mm device, cannot use this cable. Users who require a longer reach between supply and device will also need a different length.

Deciding specification

The only detail that determines fit is the connector pair: a 5.5 mm by 2.1 mm female input and a 5.5 mm by 2.5 mm male output with pin. Match those two sizes to your equipment and the adapter will work.

Questions about this item

Will the 5.5 mm by 2.1 mm female connector run hot during all-day use?

It is a passive adapter with no active components, so it does not generate measurable heat during continuous operation.

Must my power supply already have a 5.5 mm by 2.1 mm male tip to plug into this converter?

Yes, the input side is a 5.5 mm by 2.1 mm female jack that accepts a matching male plug from your existing adapter.

Can I keep using my older device that needs a 5.5 mm by 2.5 mm centre-pin connector with this cable?

The output end is a 5.5 mm by 2.5 mm male plug with centre pin, so it fits legacy gear requiring that exact barrel size.
