Questions about this item

Will the 4.5*3.0mm connector or the 19.5V 2.31A cable need replacing before the adapter itself?

The 4.5*3.0mm connector and 19.5V 2.31A cable are fixed to the adapter; if the tip frays or the cord insulation cracks the whole unit is replaced.

What limit appears first when the 45W output runs continuously?

Built-in overload, over-voltage and short-circuit protection will shut the adapter down before the 45W thermal limit is reached.

How much heat or fan noise does the 100-240V 1.2A input produce during all-day use?

The adapter has no fan; it runs silently and warms to a moderate temperature typical for a sealed 45W supply.
