DC Power Jack Adapter

This adapter converts a 5.5x2.1mm female DC jack to a 6.3x3.0mm male straight blade plug. It enables connection between laptop power ports and larger barrel connectors. The unit suits users adapting existing chargers or replacing damaged cable ends. It is a passive component with no active electronics.

Compact Black Green Silver Housing

The straight blade plug measures 40 x 12mm and weighs 5g. Its metal contacts are housed in a black, green and silver tone shell. The straight orientation keeps the cable exit in line with the jack. The snug fit reduces accidental disconnection during daily movement.

Replaces Mismatched Barrel Connectors

Use this when a power supply terminates in a 6.3x3.0mm plug but the device requires a 5.5x2.1mm jack. It avoids cutting and soldering cables. The jump is worth it only when both connector sizes match the specifications exactly.
