135W 20V AC Adapter for ThinkPad X1 Extreme

This 135-watt AC adapter delivers 20 volts at 6.75 amps for the Lenovo ThinkPad X1 Extreme. It replaces the original Lenovo 135W and 90W chargers and is built as a new compatible unit. The package includes a UL-listed 6-foot AC cord and a 6-foot DC cord for extended reach.

Capacity and headroom: 135W output for standard

The adapter supplies up to 135 watts of continuous power, matching the factory rating for everyday charging and operation. It does not replace 170W or 230W adapters, so systems that require those higher-wattage units will not be supported. Buyers who need more output for demanding configurations cannot use this model.

Slim plug tip and safety protections decide fit

The connector uses a slim plug tip designed for the listed ThinkPad X1 Extreme part numbers. Built-in protections cover overload, short circuit, over-voltage, over-current and over-temperature conditions. A durable sealed case resists water and humidity while maintaining steady power efficiency.

Questions about this item

Will this 135W 20V 6.75A adapter charge a ThinkPad X1 Extreme that originally shipped with a 90W unit?

Yes, the adapter replaces Lenovo 135W and 90W chargers for the listed X1 Extreme models, so it will charge a unit that came with a 90W brick.

How can I verify the adapter is delivering power correctly once connected?

The ThinkPad should show a charging indicator and report the 135W input in the system power settings when the adapter is plugged in.

What cables are included and is there anything else I need to buy?

A UL-listed 6 ft 3-prong AC cord and a 6 ft DC cord are included; no extra cable is required for the supported X1 Extreme models.
