Purpose and audience

This Fervit cable converts a DC 5.5x2.1mm barrel input into a USB-C Power Delivery output up to 140W. It suits users who need to power USB-C laptops, tablets or phones from a compatible DC source such as a high-wattage adapter or portable power station. The 18cm length keeps the connection tidy on a desk or in a bag.

Compatibility checks

Your DC source must deliver between 15V and 20.5V and be rated for the wattage your device requires. The USB-C device must accept 5V, 9V or 20V PD profiles up to its maximum draw. Verify the device's rated voltage and current before connecting to avoid damage. The braided jacket adds durability for frequent plugging and transport.

Upgrade context

The cable replaces a fixed barrel-to-barrel lead or a lower-power USB-C charger when you want a single high-output DC source for multiple USB-C devices. It is not for users who need a longer reach between the power brick and the device, or who require a direct AC wall plug without an external DC adapter.

Questions about this item

Does the cable include the DC power supply or do I need to provide my own 15V-20.5V source?

The cable only provides the DC 5.5x2.1mm to USB-C connection; you must supply a compatible 15V-20.5V DC power source separately.

Which laptops can use the full 140W 20V/7A output this cable supports?

It works with USB-C laptops that accept 20V/7A PD input, such as MacBook Pro 2018, 2019, 2020 models, Dell XPS and Chromebooks supporting 20V/9V/5V profiles.

What does the 140W rating mean when I plug this 18cm cable into my laptop?

It delivers up to 140W at 20V/7A when your charger supplies 15V-20.5V DC and your laptop negotiates that PD profile; lower profiles like 100W, 65W, 9V/2A or 5V/1.5A are also supported.
