Questions about this item

Will the 65 W rating hold during long sessions without the adapter overheating?

The unit delivers 19 V at 3.42 A continuously and accepts 100 to 240 V input at 50 to 60 Hz, so it maintains its 65 W output under sustained load.

How much heat or fan noise should I expect when the charger runs all day?

No fan is present; the black plastic enclosure relies on passive cooling and stays warm but not hot during continuous operation.

My laptop uses a 5.5 mm × 2.5 mm barrel plug with side contacts and no centre pin — will this tip fit?

Yes, the connector matches that exact 5.5 mm outer diameter, 2.5 mm inner diameter design with side shrapnel and no centre pin.
