This 90-watt AC adapter delivers 20 volts at 4.5 amps through a 7.9 by 5.5 millimetre barrel connector. It is built for owners of compatible ThinkPad models who need a replacement or spare power supply. The unit accepts a wide 100 to 240 volt input range for worldwide use.

Connector size and voltage check

Before ordering, verify that the original charger specifies 20 volts and 4.5 amps output and uses a 7.9 by 5.5 millimetre tip. Confirm the laptop's required part number appears in the compatibility list supplied with this product. Ensure the wall outlet accepts a three-prong plug.

Questions about this item

Does the box include both the AC adapter and a mains power cord, or must the cord be bought separately?

The package contains one AC adapter and one 48 inch AC power cord, so no separate mains lead is required.

The title lists 90 W at 20 V 4.5 A — is that the only output option or are there other versions to choose?

This model delivers a single fixed output of 20 V at 4.5 A for 90 W; no alternative voltage or current versions are offered.

Will the 20 V 4.5 A rating actually run a ThinkPad X230 or T440p under full load without throttling?

The adapter supplies up to 90 W at 20 V 4.5 A, matching the original 90 W part numbers listed for those models, so full-load operation is supported.
