170W replacement for ThinkPad P17 and P50

This 170 watt AC adapter replaces the original Lenovo 135W and 170W chargers for ThinkPad P17 and P50 models. It supplies 20 volts at 8.5 amps to power the laptop and charge the battery whether the system is on or off. The unit is new and built with a ruggedised case sealed against moisture and high humidity. Buyers needing a 230W or 300W charger for other ThinkPad models cannot use this adapter.

Sustained output with worldwide input

The adapter accepts AC 100 to 240 volts at 50 to 60 hertz for worldwide compatibility. Internal safety features filter input line voltage spikes and limit output voltage or current to protect the laptop during continuous operation. High power efficiency delivers consistent and continuous power under sustained load. A UL listed three-prong AC cord and DC cord each measure six feet for flexible placement.

20V 8.5A output decides fit

The single specification that determines compatibility is the 20 volt 8.5 amp output delivering 170 watts maximum. This matches the original Lenovo 135W and 170W adapters but does not replace 230W or 300W units. Verify your ThinkPad requires exactly this voltage and current before purchase.

Questions about this item

How much heat or noise does the 170W adapter produce when it runs all day?

The brick has no fan and relies on passive cooling; it will get warm during sustained 170W load but stays silent and within normal operating temperature for a sealed 26.5 oz unit.

What must I already own to use this adapter with my ThinkPad?

You need a ThinkPad P17 or P50 model that originally shipped with a 135W or 170W 20V 8.5A slim-tip charger; the adapter does not fit systems requiring 230W or 300W bricks.

Will this 170W unit work alongside the 135W charger I kept from my older ThinkPad?

Yes — both output 20V and share the same slim-tip connector, so you can swap them freely; the 170W brick simply provides more headroom for heavy workloads.
