5.5 x 2.1 mm to 3.5 x 1.35 mm DC power adapter

This cable connects a 5.5 mm by 2.1 mm male barrel plug to a 3.5 mm by 1.35 mm male barrel plug. It is intended for internal DC power routing between compatible devices. The adapter suits builders who need to match these specific barrel sizes inside a chassis.

Practical limits of the barrel interface

The connection relies on a friction fit and centre-positive polarity typical of these barrel dimensions. No locking mechanism secures the plugs, so vibration can loosen them over time. Current capacity is constrained by the 1.35 mm centre pin and thin wire gauge. Voltage drop becomes significant on longer runs not covered by this short cable.

Highlights

  • Connect 5.5 mm barrel plugs to 3.5 mm jacks
  • Male-to-male design links power sources directly
  • 1 mm centre pin matches common DC adapters
  • 35 mm tip fits compact device inputs

Questions about this item

Should I pick the 5.5 x 2.1 mm or the 3.5 x 1.35 mm end for my device?

Match the connector to your equipment: the larger 5.5 x 2.1 mm plug fits the power source, while the smaller 3.5 x 1.35 mm plug goes into the device you are powering.

What does the 5.5 x 2.1 mm to 3.5 x 1.35 mm sizing mean once the cable is installed?

It bridges a standard 5.5 mm barrel jack to a smaller 3.5 mm jack, letting you run a common power supply into hardware that needs the 1.35 mm pin diameter.
