Questions about this item

How can I verify the 19V 2.1A output is stable after connecting the 3.0*1.1mm tip?

The adapter supplies 19V at 2.1A for 40W; a multimeter on the 3.0*1.1mm barrel should read close to 19V under load, and the laptop charging indicator will confirm normal operation.

What comes in the box and do I need a separate mains lead?

The package includes the 40W AC adapter with fixed 3.0*1.1mm output cable; a standard IEC C7 or C13 mains cable for your region must be purchased separately if not already owned.
