Connector Size and Function

This adapter converts a 5.5 x 2.5mm male DC plug to a 5.5 x 2.1mm female jack for power connections. It suits users needing to match different barrel connector sizes on existing equipment. The pack contains two identical units for spare or dual-device use. Buyers requiring other inner pin diameters or polarity configurations cannot use this item.

Build Integration and Clearance

Each unit measures 12 x 40mm with a 0.5 x 1.6 inch diameter and length profile. The mixed metal and plastic construction weighs 10g per pair, adding minimal bulk to a cable run. No tools are required for installation beyond pushing the connectors together. Installations needing right-angle geometry or locking collars will need a different adapter style.

Questions about this item

What is the maximum current the 5.5 x 2.5mm male plug can handle continuously?

The adapter uses a standard 5.5 x 2.5mm barrel interface; continuous current limits depend on the power supply and cable gauge used, not the adapter itself.

Does the metal contact area heat up when the adapter runs all day?

The connector body measures 12 x 40mm and combines metal contacts with a plastic housing; under normal DC loads it remains cool to the touch.
