Questions about this item

Will the 7.9 mm x 5.5 mm connector tip wear out and need replacing?

The barrel connector is a standard 7.9 mm by 5.5 mm size; replacements are widely available if the tip becomes loose or damaged.

What limits the adapter first when running a ThinkPad W540 under continuous load?

The 170 W output ceiling at 20 V and 8.5 A is the hard limit; sustained loads above that will trigger protection shutdown.

How hot or noisy does the brick get when powering a Y70-70 all day?

It is a fanless sealed unit, so it runs silent; the case will become warm as it dissipates up to 170 W continuously.
