170W USB-C Charger for ThinkPad P and Legion

This 170W AC adapter replaces the original charger for Lenovo ThinkPad P-series mobile workstations and Legion gaming laptops. It delivers 20V at 8.5A and accepts 100V–240V input for worldwide use. The unit is aimed at owners of P50, P51, P52, P53, P70, P71, P73, W540, W541, T470P, T440P, T540P, T460P, X1 Extreme Gen 1–4, P1, P15, P17, T15g, T15p Gen 1–2, ThinkBook 15p, Legion Y50-70, Y520, Y530, Y720, Y730, Y740 and compatible Yoga 15 models.

Continuous 170W output

The adapter sustains its full 170W rating under prolonged loads rather than only in short bursts. It also powers systems that originally shipped with 135W (20V 6.75A) or 150W (20V 7.5A) bricks, so one unit covers multiple ThinkPad generations. Built-in protections guard against short circuit, over-voltage, over-current and internal overheating during extended sessions.

Direct barrel-tip fit with included AC cable

The connector matches the slim rectangular tip used on the listed ThinkPad and Legion models, so installation is a simple swap of the old brick. The package supplies the detachable mains lead, removing the need to reuse a worn cable. Buyers whose laptops charge exclusively via USB-C Power Delivery cannot use this barrel-tip adapter.

Questions about this item

Does the 170 W adapter run hotter or louder than the original 135 W brick when charging a ThinkPad P50 all day?

It delivers 20 V at 8.5 A with the same input range as the original, so heat and noise stay comparable during continuous use.

Which cable must I already have to connect this charger to a ThinkPad T470p?

The unit uses the standard rectangular 20 V tip found on ThinkPad models from the W540 through P15 generations, so your existing cable fits directly.

Will this 170 W unit safely charge an older ThinkPad W540 that shipped with a 135 W supply?

Yes — it is rated for 20 V 8.5 A 170 W and explicitly listed as compatible with 20 V 6.75 A 135 W and 20 V 7.5 A 150 W systems.
