  • AC Adapter Current8.5A
  • AC Adapter Output Power170W
  • 170W output powers demanding ThinkPad P17 workloads
  • 20V 8.5A matches original Lenovo 135W and 170W charger specs

Compatible ThinkPad P17 models

This 170W AC adapter replaces the original Lenovo charger for ThinkPad P17 units including 20SN003BUS, 20SN003CUS, 20SN003DUS, 20SN003EUS, 20SN003FUS, 20SN003GUS, 20SN003VUS and 20SN003WUS. It matches the 20V 8.5A output required by these workstations. Buyers needing a 230W, 300W or 330W power supply cannot use this adapter.

Thermal and power behaviour

The adapter accepts 100–240V input at 50–60Hz for worldwide use. Internal safety circuitry filters voltage spikes and limits output to protect the laptop. A ruggedised case resists moisture and high humidity during mobile use. High power efficiency delivers consistent 170W output without excessive heat buildup.

Replacement scope and upgrade value

This unit replaces genuine Lenovo 90W, 135W and 170W adapters (part numbers 36200317, 36200320, 36200321, 45N0370, 45N0371, 45N0372). It does not replace 230W, 300W or 330W chargers. The 6 ft AC cord plus 6 ft DC cord eliminates the need for extension leads in most setups.

Questions about this item

How do I install the 6 ft 3-prong AC cord and 6 ft DC cord without straining the connector?

Plug the 3-prong cord into the adapter brick first, then into the wall outlet; route both 6 ft cords so the DC plug enters the ThinkPad P17 straight without bending — the step people skip is securing the brick so weight does not pull the tip sideways.

Which parts of this 170W 20V 8.5A adapter will need replacement over time?

The 6 ft AC cord and 6 ft DC cord are the wear items; inspect the strain reliefs near the brick and the barrel tip for fraying after heavy travel, and swap the cord set if insulation cracks appear.

At what load does the 170W limit appear first during sustained use?

Continuous draw at 20V 8.5A reaches the 170W ceiling; the adapter will throttle or shut down if the P17 demands more than 170W, so it cannot replace a 230W, 300W or 330W unit.
