5.5 by 2.5mm barrel connector

The single specification that decides fit is the 5.5 millimetre outer diameter and 2.5 millimetre inner diameter barrel connector. Only laptops designed for this exact plug geometry will connect securely and receive the correct 19 volt supply. Check the original adapter tip or the laptop service manual before ordering.

Questions about this item

Does the 5.5 x 2.5 mm connector tip wear out and need replacement?

The barrel connector is a fixed part of the cable; if the tip becomes loose or damaged the entire adapter must be replaced.

What limits continuous operation of the 65 W output?

The adapter is rated for 19 V at 3.42 A; sustained loads at that level will hit the 65 W ceiling first.

How much heat and noise does the 65 W brick produce during all-day use?

It is a fanless sealed unit, so it runs silently and warm to the touch under full 65 W load.
