  • 135 W output charges ThinkPad W510 quickly

Target Device and Power Rating

This 135W AC/DC adapter is built as a direct replacement for the Lenovo ThinkPad W510 carrying part number 4391-P3U. It accepts a world-wide input range of 100-240VAC at 50/60Hz, making it suitable for travel or office use across different regions.

Capacity and Headroom

The unit delivers up to 135W of continuous power, matching the original specification for the W510 workstation. It will run the laptop and charge the battery simultaneously under normal workloads, but sustained maximum CPU and GPU loads may push the adapter to its thermal and current limits.

Build Quality and Connectivity

Safety circuitry includes over-current, over-voltage, short-circuit and total-power protection, backed by FCC, CE and RoHS certification. A 10 ft total cord length gives generous reach from wall socket to desk, while the smart chip and isolation materials help reduce interference and overheating during daily use.
