Adapter cable USB Type-C to DC 4.0×1.35 mm by extra digital, model CC360611, for power delivery to compatible devices

Compact adapter cable that converts a USB Type‑C power source to a DC 4.0×1.35 mm barrel connector. The adapter lets you deliver USB-C Power Delivery output to devices with a standard 4.0×1.35 mm DC input, such as many Asus laptops, routers, monitors and some printers. It supports USB Type‑C PD power profiles and is intended for powering or charging compatible equipment when a direct DC plug is needed.

Advantages

This USB Type‑C to DC 4.0×1.35 mm adapter supports up to 100 W (20 V / 5 A) via USB-C Power Delivery, allowing higher‑power devices to be supplied from modern USB-C chargers. Its compact inline design makes it easy to carry and replace lost or damaged DC plugs. The adapter is compatible with standard 4.0×1.35 mm DC sockets without a centre pin and requires only a USB-C PD capable charger and cable to deliver rated power.

Suitable for

• Powering or charging laptops that accept a 4.0×1.35 mm DC input (including many Asus models)
• Supplying power to routers, monitors and other portable electronics with a 4.0×1.35 mm barrel socket
• Adapting modern USB-C PD chargers to older devices that use a 4.0×1.35 mm DC plug

When it may not be suitable

The adapter will not convert USB-C data signals; it only carries power. Actual delivered power depends on the USB-C charger and cable used—if either does not support the necessary PD profile or current, the device may receive less power or not charge. It is not compatible with devices that require a DC connector with a centre pin or a different barrel size.

Key specifications

• Connector A: USB Type‑C (female)
• Connector B: DC barrel 4.0 × 1.35 mm (male)
• Output voltage (PD): up to 20 V
• Maximum power: up to 100 W
• Maximum current: up to 5 A
• Supported standard: USB Type‑C Power Delivery (PD)

How to use

Connect a PD‑capable USB Type‑C charger to the adapter’s USB‑C input using a suitable USB‑C cable, then insert the 4.0×1.35 mm barrel plug into the device’s DC input. Ensure the charger and cable support the required PD profile and current for your device. Monitor device charging behavior and device power indicators when first connecting to confirm correct operation.

What to consider before purchase

• Verify the device accepts a 4.0×1.35 mm barrel plug without a centre pin
• Check the device's required input voltage and current and confirm your USB‑C charger can provide the needed PD profile
• Use a USB‑C cable rated for the required current to achieve up to 5 A

Usage recommendations

Use a certified PD charger and a high‑quality USB‑C cable that supports the required current. Avoid using the adapter with devices that need a different barrel size or a centre‑pin connection. If the device does not respond, verify charger PD negotiation and consult device specifications before applying power.
