7.4×5.0 mm DC Jack to USB-C Cable

This cable adapts a 7.4 mm by 5.0 mm barrel connector to a USB-C plug for power delivery. It accepts a DC input between 15 V and 20 V and supplies up to 65 W to compatible laptops, tablets and phones. The design targets users who need to power USB-C devices from an existing barrel-output adapter.

Voltage and protocol limits

The cable only operates when the source provides 15 V to 20 V DC; lower voltages will not activate the output. It negotiates power using USB PD plus QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP profiles. Devices that require a different input range or lack support for these protocols cannot be charged.

65 W output headroom

Maximum output is 65 W delivered at 20 V and 3.25 A, with additional fixed steps at 5 V 2 A and 9 V 3 A. This covers most ultraportables and phones, but systems that draw more than 65 W or need voltages outside the 5 V, 9 V, 20 V set will not reach full performance. Buyers needing higher wattage or additional voltage steps must use a different adapter.
