Vszerda DC 4.5x3.0mm to USB-C PD 140W Cable

This 18cm braided cable converts a DC 4.5x3.0mm barrel jack input into a USB-C Power Delivery output. It is designed for users who need to power USB-C laptops, tablets or phones from an existing DC power source rated between 15V and 20.5V.

Practical limits of the DC-to-USB-C conversion

The cable accepts an input range of 15V to 20.5V and delivers a maximum output of 100W across 5V/1.5A, 9V/2A and 20V/7A profiles. To reach the advertised 140W throughput at 20V/7A, both the source adapter and the connected device must support that power level; otherwise output is limited by the lowest-capable link.

Replaces bulky proprietary chargers for travel

This short adapter cable replaces a dedicated USB-C laptop brick when a compatible DC barrel supply is already available, reducing bag bulk for 65W, 100W or 140W workflows. It is not suited for users who lack a suitable DC source or who need longer reach between outlet and device.
