170W AC Adapter for ThinkPad W520 W530

This 170W AC/DC adapter replaces the original power supply for Lenovo ThinkPad W520 and W530 laptops. It accepts 100-240VAC input at 50/60Hz for worldwide use. The unit includes a 10 ft power cord for flexible desk placement. Safety features cover over current, over voltage, short circuit and total power protection.

Replaces worn or lost factory chargers

The adapter matches the 170W output required by W520 and W530 workstations. It fits part numbers including 427623U, 427637U, 428443G, 4276001 and 4276004. The jump is worth it when the original brick fails, the cable frays or a spare is needed for travel. FCC, CE and RoHS certifications confirm baseline compliance.

Delivers full 170W for high-load work

The supply comfortably handles CPU and GPU loads typical of mobile workstation tasks such as rendering or simulation. Headroom runs out if the system draws sustained power above the rated 170W or if the tip polarity does not match the laptop jack. The 10 ft cable reaches distant outlets without extension leads.

Questions about this item

What AC input voltage range does the 170 W adapter accept?

The adapter operates on 100-240 VAC at 50/60 Hz, so it works on mains supplies worldwide without a voltage selector.

Which connector fits the ThinkPad W520 and W530 charging port?

The supplied plug matches the original Lenovo slim-tip connector used by the W520 and W530 series; align the keyed shape and push straight in until it clicks.

How long is the detachable mains lead and when should it be replaced?

The total cord length is 10 ft; replace the lead if the insulation cracks, the plug pins bend, or the adapter trips its over-current protection repeatedly.
