  • Universal 100-240V input works worldwide without a voltage converter

170W square-tip charger for ThinkPad

This 170W AC adapter delivers 20V at 8.5A through a square yellow slim tip. It accepts 100-240V input at 50-60Hz and includes a 1.5m power cord. The unit weighs 600g and uses a US-style three-prong plug. It replaces lost or damaged chargers for a wide range of Lenovo ThinkPad models.

Replaces 135W and lower adapters

The adapter supersedes 135W and 65W units that share the same square yellow tip, such as part numbers ADL135NLC3A and ADLX65NLC3A. The higher 170W rating is worth it when the laptop draws more power under load or charges the battery while running demanding workloads. It also covers legacy part numbers like 45N0361 and 45N0501 used on older ThinkPad P and T series.

Fits ThinkPad P, T, X, W, E, G, Z and Legion

The square yellow slim tip mates with the charging port on compatible ThinkPad P50, P51, T440, T450, X240, X250, W540, E440, G50 and Legion Y720 models. The 1.5m cable reaches wall outlets from a desk without strain. The 100-240V input works worldwide with only a plug adapter, freeing travellers from carrying a separate voltage converter.

Questions about this item

Will the square yellow slim tip fit my Lenovo ThinkPad P50 charging port?

Yes, the adapter uses a square yellow slim tip that matches the DC-in jack on the ThinkPad P50 and other listed models.

How do I install the adapter, and what step is often missed?

Plug the US three-prong power cord into a 100-240V outlet, then insert the square yellow slim tip firmly until it clicks; the click confirms full seating.

When should I replace the 1.5 m power cord?

Replace the cord if the insulation cracks, the plug pins bend, or the adapter becomes intermittent when the cable is flexed.
