Fervit DC Jack 4.0x1.7mm USB-C PD Cable

This cable converts a DC 4.0x1.7mm jack input into a USB-C Power Delivery output for charging compatible laptops, tablets and phones. It targets users who want to power USB-C devices from an existing DC power source rated between 15 and 20 volts.

Supported fast-charge protocols and safety

The cable handles USB PD plus QC2.0, QC3.0, DCP, PE+1.1, PE2.0, FCP, AFC, SFCP and SCP standards, delivering up to 65 watts at 5V/2A, 9V/3A or 20V/3.25A. The supplier warns that incorrect voltage or current selection can damage the connected device.

Simple plug-in connection with voltage caution

Installation is a direct plug from the DC jack to the USB-C port with no drivers required. The main risk is applying an input outside the 15-20V range or mismatching the device's required profile, which the supplier says may cause hardware damage.

Questions about this item

Will the DC 4.0x1.7mm plug wear out and need replacing?

The DC 4.0x1.7mm plug is a passive connector with no moving parts; it only needs replacement if the barrel or centre pin is physically damaged.

What limits the cable first during sustained 65W use?

The 65W maximum output (20V/3.25A) is the hard limit; sustained loads at that level will hit the cable's rated ceiling before any other factor.

How much heat does the cable produce when running all day at full load?

At 65W continuous output the cable will warm up, but it contains no active cooling or power electronics beyond the PD negotiation chip, so heat stays modest.
