Compatible ThinkPad power adapter

This 90W AC adapter supplies 20V at 4.5A for Lenovo ThinkPad T470p, T540p and X1 Carbon models. It replaces the original charger for machines that require this exact voltage and current combination.

Output specification decides fit

The unit delivers 20V 4.5A at 90W maximum; your laptop must list 20V 4.5A on its label or in its service manual. Models that specify 19.5V 4.62A or 19V 4.74A instead will not charge correctly with this adapter.

Simple plug-in replacement

The package includes a 6 ft 2-prong AC cord for worldwide 100-240V input. No drivers or configuration are needed. Buyers who need a different voltage, a higher wattage or a USB-C power delivery connector cannot use this adapter.
