Questions about this item

Should I choose the 19 V 2.1 A version or the 40 W model?

They are the same unit: 19 V at 2.1 A equals 40 W, so the listed version covers both ratings.

What does the 2.1 A rating mean once the adapter is plugged in?

It means the brick can supply up to 2.1 amps continuously at 19 volts, giving the laptop a maximum of 40 watts under load.

Which connector standard does the ADP-40PH BB use and what does it limit?

The barrel connector on this ADP-40PH BB limits the adapter to the 19 V 2.1 A output specified for compatible Delta units.
