170 W replacement adapter for ThinkPad W510

This 170 W AC adapter replaces the original charger for Lenovo ThinkPad W510 models including 4391P3U, 4391P2U, 4319, 4389 and 4391. It delivers the same output specification so the laptop charges and runs normally. The unit is built from new components and carries FCC, CE and RoHS certification.

Input range and protection limits

The adapter accepts worldwide mains input from 100 V to 240 V AC at 50 Hz or 60 Hz, making it suitable for travel without a separate voltage converter. Integrated safety circuits provide over-current protection, over-voltage protection, short-circuit protection and total power protection to guard both the charger and the connected notebook.

Compatibility checks before ordering

Confirm that your ThinkPad model number matches one of the listed part numbers and that the original power supply is rated at 170 W. Verify the connector tip fits your laptop’s DC jack and that the 10 ft total cord length reaches your preferred outlet location.
