Purpose and compatibility

This cable converts a USB-C Power Delivery charger into a direct 18-20 V DC supply for compatible laptops. It targets owners of HP models and the Lenovo ThinkPad X1 Carbon that use a 7.4×5.0 mm rectangular barrel connector and require 65-100 W input.

Sustained power behaviour

The integrated PD trigger negotiates a fixed 18-20 V output from the charger, so voltage remains stable during continuous load rather than sagging after a brief burst. The charger must be rated at 65-100 W and exceed the laptop's draw; 5 V fallback is not supported.

Build and daily use

A carbon-finish jacket protects the conductors while the USB-C female socket accepts any standard PD brick you already carry. The male barrel plug seats firmly in the laptop port, letting you leave bulky proprietary adapters at home without adding bulk to your bag.

Questions about this item

Does the built-in PD emulator trigger add noticeable heat when the cable runs at 100 W all day?

The cable uses a carbon construction and only passes power through the trigger; no active components are present, so heat stays low during continuous 100 W use.

Which charger must I already own for this cable to deliver 18-20 V to my laptop?

You need a USB-C charger rated 65 W to 100 W that supports Power Delivery at 18 V or 20 V; the cable will not negotiate 5 V.

Will the 7.4×5.0 mm DC plug fit the charging port on my older ThinkPad X1 Carbon?

Yes, the rectangular 7.4×5.0 mm male connector matches the DC input on compatible ThinkPad X1 Carbon and HP models that accept 18-20 V.
