Product Purpose

This Fervit cable adapts a 7.4×5.0 mm DC barrel jack to a USB-C connector, delivering up to 140 W for laptops, tablets and phones. It targets users who need to power USB-C devices from an existing DC source such as a proprietary AC adapter or docking station.

Interface Limits

The cable accepts a DC input range of 15 V to 20.5 V and negotiates output profiles of 5 V 1.5 A, 9 V 2 A, and 20 V up to 7 A. It supports PD, QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP, but cannot operate outside the stated voltage window or exceed the 140 W ceiling.

Installation Notes

At 18 cm including connectors, the short braided lead is plug-and-play and resists tangling. The main risk is mismatching the source voltage or device requirements; the supplier warns that incorrect voltage or current selection can damage the connected laptop or phone.
