Questions about this item

How much heat and noise does the 65 W adapter produce when it runs continuously?

The brick has no fan, so it operates silently; its 65 W rating and high efficiency keep warmth low during all-day use.

What must I already own for this charger to work with my Lenovo laptop?

You need a compatible Lenovo model such as IdeaPad 300, 300S or 500 series that accepts a 20 V, 3.25 A barrel connector.

Will this 65 W unit safely replace the original 45 W adapter on my older IdeaPad 300?

Yes — it matches the 20 V output and fits the same barrel tip, so the laptop draws only the current it requires.
