Suitable For And Unsuitable For

Suits owners of compatible ThinkPad P15 units needing a replacement 170W adapter with worldwide 100-240V input and extra-long cords. Not for users whose device requires a 230W or 300W charger, or anyone needing a different output voltage or connector type.

20V 8.5A Output Specification

The single specification that decides fit is the 20V 8.5A 170W maximum output. Only select this adapter if your ThinkPad P15 originally shipped with a 135W or 170W unit; it will not support models requiring higher wattage.

Questions about this item

Does the 20V 8.5A output match the power input my ThinkPad P15 expects?

Yes — this adapter delivers 20V at 8.5A for a maximum of 170W, which matches the original Lenovo 135W and 170W units listed for the P15 models 20ST003XUS through 20ST004DUS.

Can I keep using my older 135W Lenovo charger alongside this 170W unit?

The 170W adapter replaces both the 135W and 170W original chargers; it does not replace 230W or 300W units, so a 135W charger will work but provides less power headroom.

How do I confirm the adapter is charging the battery after I plug it in?

When connected to AC 100–240V the adapter powers the laptop and charges the battery whether the system is on or off; the ThinkPad’s charging LED will show the normal charge indication.
