170W adapter for ThinkPad P51

This 170W AC adapter supplies 20V at 8.5A to Lenovo ThinkPad P51 models including 20HH003VUS, 20HH003WUS, 20HH003XUS, 20HH003YUS, 20HH0040US, 20HH0041US, 20HH0042US and 20HH0043US. It replaces the original 135W and 170W chargers and is intended for owners who need a direct replacement for those units.

Simple plug-in replacement with long cords

The package includes a 6 ft UL listed 3-prong AC power cord and a 6 ft DC power cord so the outlet can be farther from the desk. Installation is limited to connecting the two cables and plugging the barrel tip into the laptop; the adapter accepts 100-240V input at 50-60Hz for worldwide use. The most common issue is ordering this 170W unit for a system that requires the 230W charger, which it does not replace.

Check your P51 part number and original wattage

Before ordering, confirm the laptop's exact model number matches one of the 20HH codes listed above. Verify the original charger is rated 135W or 170W; if the sticker shows 230W this adapter will not provide enough power. The output is fixed at 20V 8.5A, so the laptop must accept that voltage and current combination.

Questions about this item

How can I confirm the iTekiro 170W adapter is delivering the correct 20V 8.5A output after I plug it in?

The laptop charging indicator should light up and the battery icon must show it is charging; if the system reports the correct wattage in its power settings the adapter is working as intended.

What cables come in the box and is there anything else I need to buy separately?

The package includes a 6 ft UL listed 3-prong AC power cord and a 6 ft DC power cord; no extra cables are required for the listed ThinkPad models.

My ThinkPad P51 is one of the 20HH003VUS through 20HH0043US variants — which capacity should I choose?

This 170W unit replaces the original 135W or 170W charger for every model listed; it does not replace a 230W charger, so choose it only if your original was 170W or lower.
