Vostro 7620, 12V Power adapter?

I see all sorts of 12V power adapters for use in a car or a plane listed but not a 12V Power Adapter for Vostro 16-7620. Am I missing something?

The system ships with a 130W adapter -- I don't think you'll find either a car or plane with an electrical system that can handle supplying that much power.

You can find these for more modest notebooks that need less power, though.

130W class 12V adapters are not widely available as the typical power in a car or aircraft is not nearly enough.

My Dell Precision 3480 uses a 130W PSU and that is due to the discrete GPU in the machine

 Why Dell offers 12V power sources for so many laptops other than the Vostro 7620 seems mysterious to me. Does anyone know?

I see that Dell offers an inverter that would plug into a car's power port. But I wonder about the car's charging system being able to handle that load. Anny thoughts there?
