  • Converts 5.5×2.5 mm male plug to 6.3×3.0 mm female jack for laptop power compatibility
  • Metal contact terminals provide stable current transmission and secure connection
  • Compact plug-only design needs no cable for easy portability and installation
  • Works with notebooks, laptops and other DC-powered electronic equipment
  • Interface converter only — does not alter voltage or current parameters of power supply

DC interface converter

This adapter bridges a 5.5×2.5 mm male DC plug to a 6.3×3.0 mm female jack, letting an existing power supply fit a laptop or device that requires the larger barrel. It is a passive connector that does not alter voltage or current, so the source adapter must already match the device's electrical ratings.

Build integration

The compact plug-only design adds no cable length and needs no extra mounting space, making it a tidy solution for tight desk setups or travel kits. Metal contact terminals maintain a firm seat and steady current flow through the conversion point.

Suitability check

Ideal for technicians and users matching a spare 5.5×2.5 mm charger to equipment with a 6.3×3.0 mm port. Not suited for anyone needing voltage step-up or step-down, polarity reversal, or a replacement for a damaged power brick.

Questions about this item

Does the 5.5×2.5 mm male plug handle sustained current without overheating?

The adapter uses precision metal contacts for stable current transmission, but it cannot change the voltage or current rating of your power supply.

Will the connector become warm or audible during continuous daily use?

The compact metal design has no moving parts or electronics, so it produces no noise and minimal heat under normal loads.

What must I already own for this 5.5×2.5 mm to 6.3×3.0 mm converter to work?

You need an AC‑DC power supply with a 5.5×2.5 mm output plug and a laptop or device that accepts a 6.3×3.0 mm DC input jack.
