Power delivery cable for USB-C devices

This Fervit cable converts a 4.5x3.0mm DC jack input into a USB-C power output, supporting 65W maximum delivery at 15V or 20V. It works with laptops, tablets and phones that accept USB Power Delivery at 9V, 15V or 20V. The cable also handles QC 2.0, QC 3.0 and several other fast-charge protocols.

Check your source voltage and device limits

The input requires a DC source between 15V and 20V, so confirm your power supply matches that range before connecting. Verify the rated voltage and current of the device you intend to charge, because an incorrect supply can cause damage. The cable outputs up to 65W with profiles of 5V/2A, 9V/3A and 20V/3.25A.

Fixed connectors suit permanent or travel use

A barrel jack on one end and a USB-C plug on the other create a direct link without extra adapters, reducing wear on device ports. The moulded strain reliefs protect the solder joints during repeated plugging and unplugging. No additional mounting hardware is required, making it simple to carry or leave connected at a desk.

Questions about this item

What comes with the 4.5x3.0mm DC jack to USB-C cable and do I need a separate power brick?

The cable itself is the only item supplied. You must provide a DC power source that delivers 15 V to 20 V, such as a compatible laptop adapter, because the cable does not generate power on its own.

Which voltage version should I select for a device that charges at 20 V and 3.25 A?

Choose the 20 V PD profile; the cable negotiates up to 20 V at 3.25 A for a 65 W maximum, matching devices that require that exact voltage and current combination.

What does the 65 W rating mean when I plug this cable into my laptop?

It means the cable can pass up to 65 W (20 V at 3.25 A) from a suitable DC source to a USB-C device, provided the source supplies 15 V to 20 V and the device requests that power level.
