Questions about this item

The listing shows one voltage and current combination — how do I confirm this 18.5V 3.5A adapter is the right one for my laptop?

Match the voltage exactly at 18.5V and ensure your original charger supplies 3.5A or slightly less; the barrel plug measures 1.7 mm inner and 4.8 mm outer diameter, so compare that to your laptop's DC jack before ordering.

What does the 65W rating actually deliver when the adapter is plugged into a laptop?

It provides up to 65 watts at 18.5 volts and 3.5 amps, auto-ranging on 100–240 V 50–60 Hz mains, so the laptop draws only the power it needs while the brick stays within its rated limits.
