170W 20V 8.5A AC Adapter for ThinkPad P71 W540

This 170W AC adapter delivers 20V at 8.5A to power compatible Lenovo ThinkPad models including the P71 W540 W541 and X1 series. It replaces original Lenovo 135W and 170W adapters with a direct-fit barrel connector. The unit is new and built for daily charging and sustained workloads.

Input range 100 to 240V 50 to 60Hz worldwide use

The adapter accepts AC input from 100V to 240V at 50Hz or 60Hz for worldwide mains compatibility. Output is rated at 170W with a maximum of 180W across 19.5V 9.23A 19V 9.5A or 20V 8.5A rails. It does not replace 230W or 300W Lenovo chargers so systems requiring those higher ratings will not be supported.

Six foot UL listed cords durable case safety

A six foot UL listed three prong AC cord and a six foot DC cord give ample reach without an extension lead. The durable case resists extreme conditions and seals out water and humidity. Built in protections cover overload short circuit over voltage over current and over temperature for reliable daily operation.

Questions about this item

Should I choose this 170W adapter or a 230W model for my ThinkPad P71?

This 170W unit replaces the original 135W and 170W Lenovo chargers for the listed ThinkPad P71, W540, W541 and X1 part numbers; it does not replace the 230W or 300W models.

What does the 20V 8.5A rating mean when the adapter is powering my laptop?

The adapter delivers up to 170W at 20 volts and 8.5 amps, matching the original Lenovo 170W charger so the laptop receives the same voltage and current it expects.

What does the AC 100-240V 50-60Hz input actually cap in practice?

The wide-range input lets the adapter run on any mains supply from 100 to 240 volts at 50 or 60 Hz without a voltage switch, so it works worldwide.
