Power adaptor cable for USB-C laptops

This 18 cm cable converts a 4.5×3.0 mm DC barrel input into a USB-C power connection rated for 100 W. It targets owners of compatible laptops, tablets or phones that charge at 20 V, 9 V or 5 V and want a compact bridge from an existing barrel-style charger.

Braided jacket and fixed connectors

A woven braid sleeve protects the short run from tangling and daily flexing. Both ends are moulded plugs — DC jack on one side, USB-C on the other — so the link is purely plug-and-play with no detachable parts to lose.

Passive delivery up to 20 V 5 A

The cable carries whatever power the source provides, up to 100 W at 20 V 5 A, and also passes 5 V 1.5 A and 9 V 1.5 A profiles. It adds no active circuitry, so thermal load and noise are dictated entirely by the attached charger and device.

Questions about this item

What does the USB-C PD standard on this 100W cable cap the output at?

The cable delivers up to 100W at 20V/5A when paired with a 100W source, and steps down to 9V/1.5A or 5V/1.5A for lower-power devices.

What clearance does the 4.5x3.0mm DC jack need to seat properly?

The straight barrel plug requires a 4.5mm outer diameter and 3.0mm inner diameter port; ensure the laptop jack matches these dimensions before connecting.

How do you install this cable, and which step is often missed?

Connect the DC jack to the power adapter first, then plug the USB-C end into the device; the missed step is verifying the adapter outputs 15-20V before powering on.
