USB-C PD cable for HP and Lenovo laptops

This adapter cable converts a USB 3.1 Type-C female port into a 7.9×5.4 mm DC barrel connector. It is intended for users who want to power compatible HP laptops or a Lenovo ThinkPad X1 Carbon from a high-wattage USB-C charger.

Thermals noise and power draw

The cable contains a built-in PD trigger that negotiates 18 V to 20 V output from a 65 W to 100 W USB-C source. It does not support 5 V operation. Because the assembly is passive, it adds no audible noise or measurable heat beyond the charger itself.

PD trigger and compatibility notes

The integrated trigger chip handles the Power Delivery handshake so the charger delivers the required voltage automatically. The source charger must be rated higher than the laptop’s input demand. Compatibility varies by model, so verification is recommended before use.

Questions about this item

How do I connect the 7.9x5.4 mm DC plug to my HP laptop using this cable?

Plug the USB 3.1 Type-C female end into a 65-100 W USB-C charger, then insert the 7.9x5.4 mm rectangle plug into the laptop's DC jack; the built-in PD trigger negotiates 18-20 V automatically.

Will the PD trigger chip inside the Type-C female end wear out and need replacement?

The trigger is a passive semiconductor circuit moulded into the connector; it has no moving parts or firmware, so it does not wear out or require scheduled replacement.

What happens if I use a 65 W charger but my laptop draws more than 65 W under heavy load?

The cable only passes the voltage the charger negotiates; if the laptop demands more current than the 65 W source can supply, the charger will hit its current limit first and may shut down or throttle.
