  • 170W output powers demanding ThinkPad and Legion laptops
  • 20V 8.5A delivery matches original charger specifications

Purpose and Compatibility

This 170W AC adapter replaces the original charger for Lenovo ThinkPad P50, P51, P52, W540 and W541 mobile workstations as well as Legion Y530, Y540, Y545, Y7000 and Y720 gaming laptops. It delivers 20V at 8.5A to power the system and charge the battery whether the laptop is on or off. Buyers needing a higher wattage unit for larger workstations or a slimmer travel charger for ultraportables will not find those options here.

Capacity and Headroom

The adapter accepts worldwide input from 100 to 240V at 50 to 60Hz and provides a maximum output of 170W. This capacity comfortably handles the peak loads of the listed ThinkPad and Legion models during intensive workloads or gaming sessions. Systems requiring more than 170W or a different output voltage will not operate correctly with this unit.

Build and Cabling

A ruggedised case protects the internal circuitry against moisture, high humidity and the knocks of mobile use. The package includes a 6 ft UL-listed 3-prong AC cord and a 6 ft DC cord, giving a combined reach that eliminates the need for extension leads in most desk or hotel setups. The brick measures 6.18 by 3.31 by 1.97 inches and weighs 26.50 oz with cables attached.

Questions about this item

Can I use this 170 W adapter with my ThinkPad P51 20HH and keep the original supply as a spare?

The adapter delivers 20 V at 8.5 A for 170 W output and lists the ThinkPad P51 20HH among its compatible models, so it will power that laptop.

How do I confirm the charger is operating correctly once connected?

When plugged in, the laptop should show it is charging and run without drawing from the battery; the adapter’s internal protection limits voltage and current to safe levels.

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

A 6 ft UL-listed 3-prong AC cord and a 6 ft DC output cord are included; no extra cables are required for the listed Lenovo models.
