Fervit DC Jack 2.5x0.7mm to USB-C PD Cable

This cable converts a 2.5x0.7mm DC barrel input into a USB-C output with Power Delivery support up to 65W. It is intended for users who need to power USB-C laptops, tablets or phones from an existing DC power source.

PD and Quick-Charge protocol limits

The cable negotiates 5V at 2A, 9V at 3A and 20V at 3.25A through USB PD, QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP. It only operates when the DC source supplies between 15V and 20V, so lower-voltage adapters will not work.

Check your DC source before ordering

Verify that your existing power supply delivers 15V to 20V and can provide enough current for the 65W maximum output. Using a source outside this voltage range can damage the connected phone or laptop.
