140W DC-to-USB-C adapter cable

This 18cm cable converts a 5.5×2.5mm DC barrel input into a USB-C power output rated up to 140W. It targets users who need to power modern USB-C laptops, tablets or phones from an existing 15V to 20.5V DC source such as a high-wattage laptop brick or portable power station. The short length keeps voltage drop low for the 20V 7A maximum throughput.

Woven braid jacket with plug-and-play build

A tangle-free braided sleeve protects the conductors during frequent packing and unpacking. The moulded connectors seat firmly without wobble, so the link stays reliable when the cable is bent around tight desk corners or stuffed into a laptop sleeve. No driver installation or configuration is required; the cable negotiates supported profiles automatically on connection.

Multi-protocol negotiation for broad device support

The cable handles USB PD alongside QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP, allowing it to fall back to 5V 1.5A, 9V 2A or 20V 5A when the attached device cannot accept the full 20V 7A. Buyers whose hardware lacks USB-C PD negotiation or requires a different barrel size will need a separate adapter.
