Replacement Compatibility

This AC adapter replaces original Lenovo 135W and 170W chargers for listed part numbers. It does not replace 230W or 300W units. Buyers needing higher-wattage power for larger workstations cannot use this model.

Worldwide Input Range

The adapter accepts AC 100 to 240V at 50 to 60Hz for global use. Output delivers 20V at 8.5A for 170W continuous power with a maximum of 180W. Safety protections include overload, short-circuit, over-voltage, over-current and over-temperature circuits.

Sustained Load Behaviour

A durable sealed case resists water and humidity during extended operation. High power efficiency maintains a steady supply without thermal throttling under continuous load. The six-foot AC cord and six-foot DC cord give flexible placement for long work sessions.

Questions about this item

What length are the AC and DC power cords on this 170W adapter?

Both the UL-listed 3-prong AC cord and the DC output cord measure six feet each, giving a combined reach of twelve feet from wall outlet to laptop.

Which connector tip does the 20V 8.5A output use, and how do I attach it securely?

The adapter ships with a fixed Lenovo-compatible rectangular tip; plug it straight into the laptop’s charging port until it clicks, avoiding angled pressure that can loosen the connection over time.

Will the internal fan or capacitors need servicing during the adapter’s life?

The unit is a sealed, fanless design with solid-state protection circuits, so no user-serviceable parts or scheduled maintenance are required.
