Purpose and Compatibility

This Fervit cable converts a 4.0×1.3mm DC barrel input into a USB-C Power Delivery output up to 65W. It suits users who need to power a USB-C laptop, tablet or phone from an existing 15-20V DC source such as a compatible power adapter or portable battery.

Build and Daily Use

The cable carries a male DC jack on one end and a USB-C plug on the other, supporting a wide range of fast-charge protocols including QC2.0, QC3.0, FCP, AFC, SCP and USB PD. Maximum output profiles are 5V/2A, 9V/3A and 20V/3.25A, so the connected device negotiates the appropriate level automatically.

Pre-Purchase Checks

Confirm that your DC source delivers between 15V and 20V and can supply sufficient current for the desired output profile. Verify that the target device accepts USB-C PD input and that its required voltage and current fall within the cable’s 65W maximum rating to avoid damage.
