The DC plug measures 4.5 mm by 3.0 mm and delivers 19.5 V at 2.31 A, matching the blue-tip specification for compatible HP models. The adapter weighs 1.0300 kg and ships in generic packaging rather than retail boxing.

Questions about this item

Will the 4.5 mm × 3.0 mm blue-tip connector wear out and need replacing?

The blue-tip DC connector is a passive part with no moving contacts; it does not wear out under normal use and does not require scheduled replacement.

What limits continuous output when the adapter runs at 45 W for hours?

The 45 W rating is the sustained thermal limit; the unit will not deliver more than 19.5 V at 2.31 A continuously without overheating.

How hot or noisy does the 1.03 kg brick get on 100-240 V input all day?

The adapter is fanless and silent; under full 45 W load it becomes warm to the touch but stays within normal operating temperature for a sealed power supply.
