170W AC Adapter for ThinkPad P50

This iTekiro 170W AC adapter powers compatible Lenovo ThinkPad P50 models and charges the battery whether the laptop is on or off. It delivers 20V at 8.5A and replaces original 90W, 135W and 170W Lenovo chargers. The unit includes a 6 ft AC cord and a 6 ft DC cord for extended reach.

Suits ThinkPad P50 170W users, not 230W

Buyers whose ThinkPad P50 shipped with a 170W or lower rated charger can use this adapter directly. It does not replace 230W, 300W or 330W Lenovo chargers, so systems requiring those higher wattages need a different power supply.

20V 8.5A 170W output decides fit

The adapter provides a fixed 20V DC output at 8.5A for a maximum of 170W. Match this voltage, current and wattage to the laptop's original charger label before purchase; a mismatch means the unit will not work correctly.

Questions about this item

Does my ThinkPad P50 need to be a specific sub-model like the 20EN001FUS for this 170W adapter to fit?

The adapter is listed for the full P50 range including 20EN001FUS through 20EN001NUS and replaces the original Lenovo 135W or 170W unit.

Will this 170W adapter charge a ThinkPad P50 that originally shipped with a 230W charger?

No — the manufacturer states this unit does not replace the 230W, 300W or 330W chargers.

How can I confirm the adapter is delivering the rated 20V 8.5A output after I plug it in?

The laptop battery icon should show charging and the system power report will read 20V 8.5A when the adapter is connected.
