Power for select ThinkPad models
This 170 W AC adapter uses a slim-tip connector to supply 20 V at 8.50 A to compatible Lenovo ThinkPad systems. It accepts 120 V or 230 V mains input for use in the United States, Canada and Mexico. The unit replaces the original 43N0372 adapter and carries a lifetime limited warranty.
Input and output constraints
The adapter delivers a fixed 20 V DC output, so it cannot charge devices that require a different voltage or a higher current than 8.50 A. Its slim-tip plug fits only the listed ThinkPad models and will not connect to laptops that use a rectangular or USB-C power input. The 120 V and 230 V AC range covers North American mains but does not extend to other regional voltages.
