DC 6.0x1.4mm to USB-C 140W Adapter

This adapter converts a DC 6.0x1.4mm barrel input into a USB-C output delivering up to 140W. It is intended for users who want to power USB-C laptops, tablets or phones from an existing 135W or 140W barrel charger.

Installation and common issues

Connect the barrel plug to a compatible 18V-20V DC source and attach a USB-C cable to the output. The unit contains a built-in PD trigger that negotiates 5V, 9V, 15V or 20V profiles automatically. Verify that the connected device matches the negotiated voltage and current; mismatched ratings can damage the equipment.

140W maximum output

The adapter supplies a peak of 140W with selectable output steps of 5V/2A, 9V/3A, 15V/2A, 20V/3.25A, 20V/5A and 20V/7A. It supports PD and QC 2.0/3.0 protocols. Buyers whose devices require more than 140W or a different barrel size cannot use this converter.

Questions about this item

How can I confirm the adapter is delivering the correct voltage after connecting it to my 140 W charger?

The USB-C port will negotiate 20 V at up to 7 A with a compatible device, so a USB power meter should show 20 V output when a 140 W laptop is charging.

What comes in the package and do I need any extra cables or tips?

The adapter itself is included; you must supply a 135 W or 140 W DC charger with a 6.0 × 1.4 mm barrel plug and a USB-C cable rated for the required current.

Which voltage and current setting should I select for a 100 W laptop versus a 65 W laptop?

Both laptops will request their needed profile over PD; the adapter supports 20 V at 3.25 A for 65 W and 20 V at 5 A for 100 W automatically.
