  • World-wide 100-240V input lets you charge anywhere

Replacement 90W AC adapter

The WAWEIS adapter delivers 19V at 4.74A to replace the Lenovo 45J7717 unit. It accepts 100-240VAC at 50/60Hz for worldwide use. A 10 ft power cord provides generous reach. FCC, CE and RoHS certifications confirm compliance.

Upgrading from a worn original

This unit replaces a lost, damaged or ageing factory charger that no longer holds a secure connection. The jump is worth it when the original cable frays or the brick overheats. Built-in over-current, over-voltage, short-circuit and total-power protection guard the laptop. A smart chip adds overheating protection during extended sessions.

Capacity and headroom for daily charging

The 90W output comfortably powers compatible Lenovo laptops while charging the battery under normal workloads. It runs out of headroom if the system draws more than the rated 90W during heavy combined CPU and GPU load. The 12 month warranty period covers defects in materials and workmanship.
