USB-C to DC 5.5×2.1mm 140W PD Cable

This cable converts a USB-C Power Delivery source into a DC 5.5×2.1mm 20V output for laptops. It contains a built-in 140W PD trigger that negotiates 20V at up to 7A from a compatible charger. The connector fits devices that accept a 5.5mm barrel jack. It is intended for users who want to power a barrel-port laptop from a high-wattage USB-C supply.

Suits laptops with 5.5mm DC input needing up to 140W

The cable works with USB-C chargers rated at 135W or 140W and also passes through 135W, 100W and 65W profiles. It supports PD, QC 2.0 and QC 3.0 protocols for negotiation. Buyers whose laptops require a different barrel size, a voltage other than 20V, or more than 140W should look at other solutions. It is not for devices that charge only via proprietary connectors or lower-power USB-C ports without PD capability.

Connects a 135W or 140W USB-C charger

The Type-C male plug goes into the charger and the DC 5.5mm male plug goes into the laptop. No separate adapter brick is needed because the trigger circuit is inside the cable. This frees up a USB-C port on the charger for other devices while delivering 20V power through the barrel jack. Ensure the charger can supply 135W or 140W to reach the cable's maximum rating.

Questions about this item

What charger power rating do I need to use this cable?

The Type-C charger must deliver 135W or 140W for the cable to operate at its 140W maximum.

Will the cable work if I connect it to a 100W USB-C charger instead?

The cable also supports 135W, 100W and 65W output when paired with a charger of the matching rating.

How can I confirm the cable is delivering the correct 20V output after setup?

Measure the DC 5.5 mm connector with a multimeter; it should read 20V when the PD trigger negotiates the 140W profile.
