USB-C PD Trigger Cable 18-20V

This USB 3.1 Type-C female to DC cable carries a built-in PD emulator trigger that requests 18-20V from a compatible charger. It converts a USB-C power source into a 7.4x5.0mm rectangular barrel output for direct laptop charging.

Suits HP and ThinkPad X1 Carbon owners

Users with laptops that accept a 7.4x5.0mm barrel jack at 18-20V can power them from a USB-C PD charger. Buyers whose devices need a different voltage, a different connector size, or 5V-only operation should look elsewhere.

Requires 65-100W USB-C PD charger

The cable only functions when the connected USB-C charger delivers 65-100W and supports the PD profile needed to output 18-20V. Lower-wattage or non-PD adapters will not provide the required voltage.

Questions about this item

What DC barrel size does the 7.4x5.0mm plug fit?

The cable ends in a 7.4x5.0mm rectangular DC connector that mates with HP laptops and the Lenovo ThinkPad X1 Carbon requiring 18-20V input.

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

Plug a 65-100W USB-C charger into the Type-C female end first, then attach the 7.4x5.0mm DC plug to the laptop; the built-in PD emulator negotiates 18-20V automatically.

When should I replace the cable if the laptop stops charging?

Replace it if the USB-C female port feels loose, the DC plug pins are bent, or a known-good 65-100W charger no longer triggers 18-20V output.
