Unfortunately my laptop runs on 20V so I doubt it would work if I fed it 12V, and might never work again if I connected two in series and fed it 24V.

Switch mode power supplies that boost voltage from 12v to 20v DC are
very efficient and only have a few components. You can probably make
one from a kit for about $10 in parts.
