Questions about this item

What is the maximum power the 20 V 3.25 A output can sustain under continuous load?

The adapter delivers up to 65 W at 20 V 3.25 A, and is also compatible with 45 W requirements.

How much heat or fan noise does the unit produce when running all day?

No fan is present; the brick relies on passive convection cooling, so it generates warmth but no audible noise.

Which AC mains cable must I already have to connect this power supply to the wall?

The unit uses a standard IEC C7 figure-8 inlet, so a common two-pin mains lead is required.
