S, Simon Quellen Field pie:
Sometimes it helps to look at the actual problem you want to
solve,
rather than to help solve it in the least efficient way.

But since this is a group interested in vacuum, I'll also
offer what you asked for.

Your car already has a generator.

A lot of links...
Now the answers...
The refrigerators based on Peltie element (these under $100) are so
ineficient and thus unusable. I have two of them but they pull 40W
from my solar system and was claimed that they can get 20 centigrade
under surounding temperature. That's just not true. If I fill that
ones with already cooled stuff they slowly warm up to aprox 15
centigrade environment temperature. And this just isn't enought. The
expensive one (over $250) intended for boat or something does do the
job. But need a lot of power (at least when starting) so again not
suitable. Gas powered refrigerator's (good for me) are just
overpriced here.
On the gauges in link I think it's not possible to see if pressure
is 30 or 15 or 5 mbar. And accuracy suffer.
The pump on link seems nice one... ...if that price is the final
price. But isn't. And as I wan't to pump air and watter vapour the
oil can be contaminated to quick. But it's nice pump...
And at least I have inverter already mounted for some power tools
but all other thing is for 12 or 24V.
ahh.. the hand pump... Can that one reach 10mbar?!? I don't think
that 100mBar is reachable.
Sorry... but thanks for all suggestions.
