Power delivery scope

This 18 cm cable converts a rectangular DC jack input into a USB-C output capable of 140 W at 20 V 7 A. It targets users who need to power USB-C laptops, tablets or phones from an existing DC source such as a ThinkPad X1 style adapter.

Build integration

The cable accepts a DC input range of 15 V to 20.5 V and negotiates 5 V 1.5 A, 9 V 2 A or 20 V up to 7 A with the connected device. Its woven braid jacket resists tangling while the short length keeps cable clutter minimal on a desk or in a bag.

Upgrade context

It replaces proprietary barrel-to-USB-C dongles that top out at 65 W or 100 W, enabling full 140 W charging on compatible Mac Pro models from 2018 through 2020, XPS and Chromebook hardware. Buyers whose devices only support lower PD profiles or lack USB-C charging entirely will not benefit from the higher wattage.

Questions about this item

Will the 140W 20V 7A rating hold during long charging sessions?

The cable supports up to 140W at 20V 7A when paired with a 140W source and a device that negotiates that profile; sustained output depends on the source and device limits.

Does the 18 cm braided cable get hot or noisy when running at full power all day?

The woven braid sleeve is designed for rugged durability and heat dissipation; the cable has no active components, so it produces no noise and remains within safe temperatures at rated load.

What power source must I already have to use this DC jack to USB-C cable?

You need a DC power supply that delivers 15 V to 20.5 V input, such as a compatible laptop barrel charger, to feed the rectangular DC jack on this cable.
