Questions about this item

How often will the 4.5 x 3.0 mm blue tip connector need replacing?

The connector is a fixed part of the cable; it only needs replacement if the tip or cable shows physical damage or wear.

What limits continuous operation of the 45 W output?

The adapter is rated for 45 W continuous output; sustained loads at that level are limited by its internal thermal protection.

How much heat or fan noise does the 19.5 V 2.31 A brick produce all day?

The unit has no fan and relies on passive cooling; it warms up under load but stays within normal operating temperatures.
