DC jack to USB-C power cable for laptops

This 18 cm cable converts a 5.5×2.1 mm DC barrel input into a USB-C connector that can deliver up to 100 W at 20 V 5 A. It is built for users who need to power USB-C laptops, tablets or phones from an existing DC power source. The woven braid jacket resists tangling and wear during daily transport.

Input voltage range and output profiles

The cable accepts a DC input between 15 V and 20 V and negotiates output at 5 V 1.5 A, 9 V 1.5 A or 20 V 5 A depending on the connected device. It supports PD along with QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP protocols. Buyers must confirm their device voltage and current requirements before use to avoid damage.

100 W maximum power delivery

The single specification that determines suitability is the 100 W peak rating at 20 V 5 A. Devices that draw more than this limit cannot be powered safely through this cable. It is not for users who need to run higher-wattage workstations or charge multiple devices simultaneously from one DC source.
