Direct Replacement for ThinkPad W520

This 170W AC adapter is built as a direct replacement for the Lenovo ThinkPad W520 and part numbers 42763JU, 42763KU and 427639U. It supplies the exact power rating the original unit provides. The unit is new and manufactured with quality components to meet OEM specifications.

Worldwide Input and Extended Reach

The adapter accepts a universal 100-240VAC input at 50 or 60Hz, so it works on mains supplies around the world without a voltage switch. A total cord length of 10 ft gives plenty of reach from a wall outlet to the laptop on a desk. No extra converters or extension leads are required for normal use.

Multiple Safety Protections

Built-in safeguards include over-current protection, over-voltage protection, short-circuit protection and total power protection. A smart chip adds overheating protection while high-quality wires and isolation materials reduce interference. The adapter carries FCC, CE and RoHS certifications for regulatory compliance.

Questions about this item

Does the 170 W rating stay stable during long charging sessions?

The adapter delivers a continuous 170 W output with over-current and total-power protection circuits that prevent shutdown under sustained load.

How hot or noisy does the brick get when left plugged in all day?

The unit runs silently with no fan; overload and overheating safeguards plus high-quality isolation materials keep surface temperatures low during 24-hour operation.

Which ThinkPad models already have the matching DC plug so this works out of the box?

Direct replacement for ThinkPad W520 units carrying part numbers 42763JU, 42763KU or 427639U — the connector fits without adapters.
