170W replacement adapter for ThinkPad P17

This 170W AC adapter replaces the original Lenovo 90W, 135W and 170W chargers for the ThinkPad P17 20SN004SUS and related part numbers. It delivers 20V at 8.5A to power the laptop and charge the battery whether the system is on or off. The unit accepts 100-240V input at 50-60Hz for worldwide use.

Sustained 170W output with surge protection

Internal safety circuits filter input voltage spikes and limit output voltage and current to protect the notebook during continuous operation. High power efficiency provides consistent and continuous power without the droop seen in lower-wattage substitutes. The ruggedised case withstands harsh mobile environments and seals against moisture and high humidity.

Simple plug-in with six-foot cables

A UL-listed three-prong AC cord and a DC cord each measure six feet, giving twelve feet total reach without extension leads. The adapter does not replace 230W, 300W or 330W Lenovo chargers, so buyers needing those higher outputs must look elsewhere. No driver or software installation is required.

Questions about this item

Does the 170W adapter run hot or make noise when powering a ThinkPad P17 all day?

The ruggedised case is sealed against moisture and humidity, and high power efficiency delivers continuous power without mentioning fan noise or surface temperature.

Which Lenovo part numbers must my ThinkPad P17 already use for this 20V 8.5A adapter to work?

It replaces genuine Lenovo 45N0373, 45N0374, 45N0375, 45N0376 and 4X20E50574 chargers rated 135W or 170W.

Will this 170W unit work alongside the older 230W charger I still have for the same laptop?

The adapter explicitly does not replace 230W, 300W or 330W chargers, so it cannot substitute the higher-wattage unit you already own.
