Questions about this item

What does the 135W rating mean when the adapter is plugged into a ThinkPad W540?

The 135W output supplies enough power to run the W540 under full load and charge its battery at the same time.

What does the 100-240VAC 50/60Hz input actually cap in daily use?

The wide-range input lets the adapter work on any mains supply from 100 V to 240 V at 50 Hz or 60 Hz without a voltage switch.

How does the 10 ft power cord affect where I can place the charger?

A 10 ft cord gives plenty of reach from a wall socket to a desk or meeting-room table without an extension lead.
