What the cable does and who needs it

This Fervit adapter cable converts a DC 6.0x1.4mm barrel input into a USB-C output for charging compatible laptops, tablets and phones. It is built for users who want to power a USB-C device from an existing 140W or 65W barrel-style supply. The 18cm braided lead is plug-and-play and designed for portable use.

Capacity and headroom

The cable accepts 15V to 20V input and delivers up to 140W at 20V 7A, with additional 5V 2A and 9V 2A profiles for lower-power gear. It handles 2018, 2019 and 2020 Mac Pro models, XPS and Chrome Book units that operate on 20V, 9V or 5V. It cannot supply more than 140W, so devices requiring higher wattage will not charge at full speed.

The deciding specification

The barrel connector measures 6.0mm outer diameter by 1.4mm inner diameter; only power bricks with that exact tip will fit. Buyers whose adapters use a different barrel size cannot use this cable.

Questions about this item

Will the 6.0x1.4mm DC jack on this cable fit the barrel port I already use on my older laptop charger?

The cable has a 6.0x1.4mm DC input plug; it will connect only if your existing charger tip matches that exact outer and inner diameter.

How can I confirm the cable is delivering the 140W 20V/7A rate after I plug it in?

Check your device's battery or power settings; it should report 20V at up to 7A when the source supplies 15V-20V DC and the laptop negotiates the 140W profile.

Does the 18cm length include both connectors, and is a DC power brick supplied in the box?

The 18cm measurement covers the whole assembly including both ends; no DC power adapter is included — you must provide your own 15V-20V source.
