1: A DC adapter for your laptop.
2: A 120v inverter, and plug in.
Those are your choices. Oh, sure, you could BUILD a DC-DC covertor, but it wouldn't be worth it, I guarantee it.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

$48.75.
In recent years DC-DC converters have become very affordable, reliable and available. You are barking up the right tree. DC-AC adaptors (cheap ones) pass a nasty modified wave that can potentially kill your laptop.
