Power delivery cable for USB-C laptops

This Fervit cable converts a DC jack measuring 6.0 by 1.4 mm into a USB-C connector, delivering up to 140 W at 20 V and 7 A. It accepts an input range of 15 V to 20.5 V and supports multiple fast-charge protocols including PD, QC 2.0, QC 3.0, PPS and several proprietary standards. The 18 cm braided cable is designed for portable use with compatible laptops, tablets and phones.

Suited for users replacing a barrel charger

Buyers who need to power a USB-C laptop from an existing 140 W, 100 W or 65 W DC adapter will find this cable useful. It works with devices that negotiate 5 V, 9 V or 20 V profiles such as Mac Pro models from 2018, 2019 and 2020, Dell XPS and Chromebooks. Users whose devices require a different barrel size, a higher voltage than 20.5 V input, or a longer cable should look elsewhere.

Plug-and-play with a critical voltage check

Installation is straightforward: connect the DC plug to the power supply and the USB-C end to the device; no drivers are required. The braided jacket resists tangling during transport. The main risk is mismatched voltage or current — verify that the charger output and device requirements fall within the 15 V to 20.5 V input and the 5 V/1.5 A, 9 V/2 A or 20 V/7 A output profiles before use.

Questions about this item

What DC power source do I need to plug into the 6.0×1.4 mm jack so the cable can deliver up to 140 W?

You need a DC supply rated between 15 V and 20.5 V that can provide up to 7 A; the cable will then negotiate 5 V/1.5 A, 9 V/2 A or 20 V/5 A or 7 A with the connected device.

Will my older MacBook Pro from 2018 or 2019 charge at full speed through this cable?

Yes, the cable supports the 20 V/5 A profile used by those MacBook Pro models, so they will charge at their maximum 100 W rate when the DC source can supply it.

How can I confirm the cable is actually delivering the negotiated voltage and current after I connect everything?

Check the charging indicator on the laptop or phone, or use a USB-C power meter inline; it should show one of the supported profiles such as 20 V/5 A or 20 V/7 A depending on the device and source.
