USB-C adapter for ThinkPad X1 Carbon

This adapter converts a USB-C power source into the rectangular 11.0×4.5 mm DC connector used by the Lenovo ThinkPad X1 Carbon. A built-in PD trigger negotiates 18 V or 20 V output from a compatible 65 W or 87 W USB-C charger. It is intended for owners who want to replace the original brick with a compact GaN charger.

Check charger power and voltage before buying

Your USB-C charger must support Power Delivery at 65 W or 87 W and be able to negotiate 18 V or 20 V. The adapter does not pass 5 V, so phone chargers or low-power power banks will not work. Verify the charger’s rated output meets or exceeds the laptop’s original requirement.

Fits between a PD charger and the laptop’s DC jack

The Type-C female socket accepts the charger cable while the rectangular male plug inserts directly into the ThinkPad’s power port. No extra cables or barrels are needed. The design frees you from carrying the bulky factory adapter when a suitable USB-C PD charger is already in your kit.

Questions about this item

Does the adapter include a USB-C charger or must I supply my own 65W or 87W unit?

The adapter only provides the Type-C female input and the 11.0×4.5 mm rectangular male output; a compatible 65W or 87W USB-C charger must be purchased separately.

My ThinkPad X1 Carbon needs 20 V — will the 65W charger version still deliver that voltage?

Both 65W and 87W USB-C chargers can trigger the adapter’s PD emulator to output 18–20 V; choose a charger whose rated power meets or exceeds your laptop’s requirement.

The spec says 18–20 V output — what voltage will my laptop actually receive?

The adapter negotiates the highest supported PDO from the connected charger, so your X1 Carbon will receive 20 V if the charger offers it, otherwise 18 V.
