Check Connector Type and Voltage Before Ordering

Verify that your current adapter uses the square yellow Slim-Tip DC plug and is rated for 20V output. This charger is not compatible with USB-C, 7.95.5 mm round-tip or Surface magnetic connectors. Match your original part number against the listed compatible PNs such as ADL170NCC3A, 45N0370 or 4X20E50574 to confirm fit.

Included AC Cord and Multi-Protection Circuitry

The package supplies an AC power cord so the charger is ready to use out of the box. Built-in OVP, OCP, OTP and SCP protections guard against over-voltage, over-current, over-temperature and short-circuit conditions during extended work sessions. No additional software or drivers are required.

Questions about this item

Does the charger come with the AC power cord or do I need to buy it separately?

The AC power cord is included in the box so you can plug the adapter into a wall outlet straight away.

My ThinkPad originally used a 135W Slim-Tip adapter — should I choose this 170W model or look for a 135W unit?

This 170W adapter delivers 20V 8.5A and safely powers 135W (20V 6.75A) systems because the laptop only draws what it needs.

What does the 170W rating actually mean when the charger is connected to a ThinkPad P52 or X1 Extreme?

It supplies up to 20V 8.5A (170W) so the system can run at full performance and charge the battery simultaneously under heavy load.
