Compatible 170W AC Adapter

This WAWEIS 170W AC adapter replaces the original power supply for Lenovo ThinkPad W520 and W530 models. It delivers 20V at 8.5A for a total of 170 Watts output. The unit accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. It is built with new components and carries FCC, CE and RoHS certifications.

Thermal and Power Behaviour

The adapter includes over current protection, total power protection, over voltage protection and short circuit protection. An internal smart chip provides overheating protection during operation. Anti-interference features use better isolation materials to reduce electrical noise. These safety circuits manage power draw and heat without active cooling.

Build and Daily Use

A 10 ft total power cord length gives flexibility for desk or floor outlet placement. The connector fits the ThinkPad W520 and W530 charging ports directly. Over-charge and over-discharge protection circuits help preserve the laptop battery during extended charging sessions. The adapter is manufactured with high quality materials and tested under strict quality control standards.

Questions about this item

How do I connect the 10 ft power cord to the 20V 8.5A adapter for my ThinkPad W520?

Plug the IEC C5 mains lead into the adapter brick, then insert the 20V DC barrel tip firmly into the laptop's charging port until it clicks; the 100-240V 50/60Hz input handles any wall outlet worldwide.

Which parts of the 170W charger will need replacement after extended use?

The detachable 10 ft AC cord and the DC cable near the barrel tip see the most flexing; the internal smart-chip protection circuits are sealed and not user-serviceable.

What limits the 170W adapter first during continuous full-load operation?

Sustained 20V 8.5A output triggers the over-current and over-temperature protections, causing the unit to throttle or shut down until it cools.
