170W replacement adapter for Legion Y540 Y545

This 170W AC adapter replaces original Lenovo 135W and 170W chargers for Legion Y540, Y545, Y7000, Y7000P and Y720 models. It delivers 20V at 8.5A output for compatible laptops. It does not replace the 230W charger required by some higher-spec configurations.

Simple plug-in installation with long cords

The package includes a 6 ft UL-listed 3-prong AC cord and a 6 ft DC cord for flexible placement. Installation is a direct swap with the original adapter. The only common issue is ordering this 170W unit when the laptop actually requires the 230W model.

170W output decides compatibility

The single specification that determines fit is the 170W maximum output at 20V 8.5A. If the laptop’s original charger is rated 230W, this adapter will not provide sufficient power. Match the wattage printed on the original power brick before purchasing.
