  • 170W output powers demanding Lenovo workstations and gaming laptops
  • Multiple safety protections guard against over-current, over-voltage and short circuits

170W AC Adapter for Lenovo Laptops

The WAWEIS 170W AC Adapter replaces the original power supply for compatible Lenovo ThinkPad and Legion models. It delivers 170 watts of power to machines such as the P50, P51, P52, P53, P70, P71, P73, Y540, Y730, Y740, Y920 and Y7000 series. The unit matches OEM specifications for voltage and connector fit.

Power Delivery and Compatibility Limits

Rated at 170W, the adapter comfortably runs high-performance mobile workstations and gaming laptops that require this input level. It will not supply enough power for systems that demand a 230W brick, so buyers needing that higher headroom should look elsewhere. The charger covers a wide range of part numbers including 45N0373, 45N0487 and 4X20E50574.

Safety Features and Certifications

Built-in protections guard against over current, over voltage, short circuit and total power faults. A smart chip adds overheating protection while improved isolation materials reduce interference. The product carries FCC, CE and RoHS certifications and is assembled from 100 percent new components.

Questions about this item

Will the 170 W adapter run my ThinkPad P70 and a legacy ThinkPad W540 from the same power brick?

The 170 W unit matches the original 170 W spec for the P70, P71, P73 and W540 series, so it will power either notebook without modification.

How can I verify the charger is delivering the correct 170 W to my Legion Y740 after I plug it in?

The adapter includes overload, over-voltage, over-current and short-circuit protection; a steady LED on the tip and stable battery charge in Windows confirm normal operation.

Does the package include a UK mains lead or only the IEC C5 "cloverleaf" cable?

The box contains the 170 W power brick and a detachable IEC C5 mains cable; no additional cables are required for standard UK outlets.
