Adapter cable extra digital USB Type-C to DC 6.3×3.0 mm, power delivery connection

Adapter cable extra digital USB Type-C to DC 6.3×3.0 mm converts a USB-C power source into a DC barrel plug (6.3×3.0 mm). It lets you use USB Type-C chargers or power banks to supply power to laptops and other devices that accept a 6.3×3.0 mm DC input without a centre pin. The adapter supports USB Power Delivery so it can carry higher voltages and currents when used with a compatible USB-C charger and cable.

Advantages

The adapter supports up to 100 W (20 V / 5 A) via USB Type-C Power Delivery, enabling charging of devices that require higher power. Its compact inline design requires no external converter and plugs directly into standard 6.3×3.0 mm DC sockets without a centre pin. Compatibility with common laptop barrel ports makes it a convenient solution for powering or charging portable equipment from modern USB-C power sources.

Suitable for

• Charging laptops and notebooks that use a 6.3×3.0 mm DC barrel jack without a centre pin (e.g., some Toshiba and NEC models)
• Powering portable electronics and small appliances that accept a 6.3×3.0 mm DC input
• Using USB-C chargers or power banks to supply devices without native USB-C power input

When it may not be suitable

This adapter is not suitable for devices that require a barrel connector with a centre pin or a different barrel size; it only fits 6.3×3.0 mm sockets without a centre pin. Actual power delivery depends on the capabilities of the USB-C charger and the USB-C cable used; if either the charger or cable does not support the required PD profile or sufficient current, the device may charge slowly or not at all.

Key specifications

• Input connector: USB Type-C (female)
• Output connector: DC barrel 6.3×3.0 mm (male), without centre pin
• Maximum output voltage: 20 V
• Maximum power: up to 100 W
• Maximum current: up to 5 A
• Charging standard: USB Type-C Power Delivery (PD)

How to use

Connect a compatible USB Type-C PD charger or power bank to the adapter’s USB-C inlet, then plug the DC barrel end into the device’s 6.3×3.0 mm DC input. Ensure the USB-C charger and cable support the required PD output and current for your device. Verify the device’s power requirements before connecting and observe polarity and fit when inserting the barrel connector.

What to consider before purchase

• Confirm your device uses a 6.3×3.0 mm DC barrel jack without a centre pin
• Check the power (voltage and current) required by the device and whether your USB-C charger and cable can supply it via PD
• Be aware that actual charging speed and available power depend on the charger and cable quality and PD support

Usage recommendations

For reliable charging, use a USB-C charger and cable rated for PD and sufficient current (up to 100 W / 5 A). Avoid adapters and cables of unknown quality and verify connector fit before powering sensitive equipment.
