Your battery will go flat

No they detect when the battery is getting low and shut off

But this is normally to protect the battery from being run flat, which
lead acid types don't like. Are you *sure* there would still be enough
charge left to start the car?


Your cigar lighter fuse will blow

For heavier loads you connect straight to the battery with the supplied
leads

Then you've got the problem of the car not being 'sealed' to the outside,
as the OP wanted. Unless you do some serious re-wiring.

You will burn out some wiring

See previous

You will need a second auxilliary battery and suitable charge
controllers.

only if the engine isn't running

The alternator will never handle the load.

Yes it will, unless its a toy one

Few are more than 100 amps. So say about a kilowatt. A domestic kettle
takes twice this. And a 2kW invertor will cost serious money. Better to
tow a generator. ;-)

Depending on how you try to do it of course.
