USB-C PD trigger cable for 18-20 V laptops

This cable converts a USB-C female input into a 7.4x5.0 mm DC barrel output for laptops that require 18-20 V power. It is intended for users who want to charge compatible HP or Lenovo ThinkPad X1 Carbon models from a 65-100 W USB-C charger instead of the original brick. The built-in PD trigger negotiates the required voltage automatically.

Carbon construction with fixed barrel connector

The housing uses carbon material and terminates in a rectangular male DC plug that mates directly with the laptop's power port. A USB-C female receptacle on the other end accepts the charger's cable, so no extra adapters are needed. The fixed barrel size means the cable only fits devices with a matching 7.4x5.0 mm jack.

Limited to 18-20 V PD profiles above 65 W

The trigger does not support 5 V output and will not work with chargers rated below the laptop's power draw. If the source cannot supply 65-100 W at the required voltage, charging will not start. Buyers needing lower voltages or different barrel sizes cannot use this cable.

Questions about this item

Does the USB 3.1 Type-C input cap the power delivery at 100 W?

The cable accepts 65 W to 100 W PD chargers and passes 18 V to 20 V DC to the laptop; 5 V output is not supported.

What DC barrel size does the 7.4×5.0 mm rectangle plug need on the laptop side?

The output end is a 7.4 mm by 5.0 mm rectangular male connector that fits matching HP and Lenovo ThinkPad X1 Carbon power ports.

How do I connect the cable so the PD trigger activates correctly?

Plug a 65 W to 100 W USB-C PD charger into the female Type-C end first, then insert the rectangular DC plug into the laptop; the charger must exceed the laptop's power draw.
