Questions about this item

Does the adapter ship with a mains cable or do I need to buy one separately?

The adapter is supplied as the power brick only; a compatible C5 or C7 mains lead must be purchased separately if you do not already have one.

The listing shows 65 W, 20 V and 3.25 A — which figure should I match to my Dell laptop?

Match the 20 V output and the 3.25 A current; the 65 W rating is the resulting maximum power and will cover any Dell model specifying up to that wattage.

Will the 65 W rating actually charge my laptop while I am using it, or only in sleep?

At 20 V and 3.25 A the adapter delivers up to 65 W, which is enough to run and charge most Dell ultrabooks and business notebooks under normal workloads.
