Compatible models

This 170W AC adapter powers Lenovo ThinkPad P70, P71 and W541 mobile workstations. It matches the original 20V 8.5A specification for models including 20ER, 20HK, 20EF and 20EG series. The unit replaces 135W and 170W chargers but does not replace 230W units.

Cord length and safety

A 6 ft UL listed 3-prong AC cord and a 6 ft DC cord give generous reach between wall outlet and laptop. The case resists water and humidity while built-in overload, short-circuit, over-voltage, over-current and over-temperature protections guard the system during daily use.

Upgrade path and limits

Users moving from a 135W brick gain extra headroom for full performance under load. The adapter cannot supply a 230W requirement, so buyers needing that higher rating must seek a different unit. Worldwide 100-240V input supports travel without a voltage converter.

Questions about this item

Does the 20V 8.5A output fully support the 170W rating on ThinkPad P70 and P71 models?

Yes, 20V multiplied by 8.5A delivers 170W, matching the original charger specification for the listed P70 and P71 part numbers.

What connector size does this adapter use to fit the ThinkPad W541 and P-series laptops?

It uses the standard rectangular 20V slim-tip connector required by ThinkPad W541 20EF 20EG and P70 P71 models.

What is the correct order for connecting the 6 ft AC cord and 6 ft DC cord during installation?

Plug the 3-prong AC cord into the wall outlet first, then connect the DC plug to the laptop; reversing the sequence can trigger the overload protection.
