Compatible replacement charger

This AC adapter replaces the original power supply for Lenovo ThinkPad X1 Carbon models 20A70037US, 20A7002FUS, 20A7002QUS and 20A7002JUS. It delivers 20V at 4.5A for 90W output and also supports 20V 3.25A 65W requirements. The unit accepts worldwide input from 100 to 240VAC at 50/60Hz. A power cord cable is included in the box.

Output capacity and limits

The adapter provides up to 90W, covering the higher power draw of the listed ThinkPad X1 Carbon configurations. It also operates safely at 65W for lighter loads or compatible models. Overvoltage, short-circuit and overheating safeguards protect the laptop during charging. It will not suit devices that require a different voltage or connector type.

Connector and voltage match

The critical specification is the 20V DC output with the correct barrel connector for the four listed ThinkPad X1 Carbon part numbers. CE, FCC and RoHS certifications confirm regulatory compliance. Smart Chip Technology ensures full communication with the laptop battery management system. Buyers needing a different voltage, wattage or tip size must choose another adapter.
