Questions about this item

How much heat does the 75W adapter produce when running continuously?

The adapter draws 100-240V at 50-60Hz and delivers 19.5V at 3.96A, so typical efficiency losses appear as modest warmth rather than high heat.

What must I already own for this 6.5mm×4.4mm connector to work?

You need a Sony VGN-BX546, BX546B, BX670P, BX675P, BX740NW or BX740P laptop with a matching DC jack.

Will the 19.5V output safely charge my older Sony VGN-BX546 alongside newer BX740 models?

Yes, the 19.5V 3.96A output matches the original spec for every listed model from the BX546 through the BX740 series.
