DC Jack 7.9x5.4mm Input to USB-C

This cable adapts a DC jack input of 7.9x5.4mm to a USB-C output for charging compatible laptops tablets and phones. It is built with a woven braid sleeve for tangle-free durability and a compact 18cm length including connectors. The plug-and-play design requires no drivers or configuration.

15V-20V Input Range Limits Use Cases

The cable only accepts a DC input between 15V and 20V so it cannot be used with lower voltage barrel adapters or standard USB-A sources. It supports PD and multiple proprietary fast-charge protocols but the connected power supply must match the required input voltage range. Mismatched voltage can damage the attached device.

100W Maximum Output With 20V5A Peak

At 20V5A the cable delivers up to 100W suitable for 100W and 65W laptops including MacBook Pro models from 2018 2019 2020 and XPS or Chromebook devices. Lower profiles of 5V1.5A and 9V1.5A handle phones and tablets. Devices needing more than 100W or a different fixed voltage will not charge correctly.
