4.8x1.7mm DC Jack to USB-C PD Cable

This cable converts a 4.8x1.7mm DC barrel input into a USB-C power plug supporting Power Delivery at 9V, 15V and 20V up to 65W. It is intended for users who need to power USB-C laptops, tablets or phones from an existing DC power source rated between 15V and 20V.

Barrel connector and USB-C plug

The 4.8mm outer by 1.7mm inner barrel jack fits compatible DC adapters, while the USB-C plug delivers negotiated voltages of 5V at 2A, 9V at 3A and 20V at 3.25A. Supported protocols include QC2.0, QC3.0, DCP, PE+1.1, PE2.0, FCP, AFC, SFCP, SCP and USB PD, enabling broad device compatibility when the source voltage matches the required input range.

65W maximum output with multi-protocol negotiation

The cable handles up to 65W output once the connected charger and device agree on a supported voltage and current level. Correct voltage verification is essential because mismatched input can damage the attached hardware. Thermal behaviour and acoustic noise depend on the external power supply and the powered device rather than on the cable itself.

Questions about this item

What input voltage range does the 4.8x1.7mm DC jack require for the cable to negotiate 65 W output?

The cable accepts 15 V to 20 V DC on the 4.8x1.7 mm barrel connector and will request up to 65 W over USB-C PD.

What outer and inner diameters must my power supply's barrel plug have to fit the 4.8x1.7 mm jack on this cable?

The jack is sized for a 4.8 mm outer diameter and a 1.7 mm centre pin; the supply's plug must match those dimensions exactly.

Which step do people often miss when connecting this cable to a laptop?

Confirm the laptop charges at 15 V or 20 V via USB-C PD before plugging in; the cable will not step voltage up or down.
