What happens if you apply 12 volts to the output side, will that produce
120 to 140 volts on the input side? or do you need a converter
specifically designed to go the other way?
No. Applying power to the output won't produce any power at the input.
It is possible to design bilateral converters that work both ways; but
it costs more and so is pretty rare.
But, you can buy 12vdc input converters that have outputs at just about
any voltage and frequency you might like. Certain combinations are
popular (like 12vdc in, 120vac 60hz out), so they are relatively cheap
and easy to find. Other combinations aren't that easy.
The idea is to take a 12 volt (or 24 volt) battery with high amphrs and
use the electronics to produce 120 volts at a tenth of the battery's
rated amphrs to run a 120 volt DC motor using lithium based batteries.
You can do that. The circuit that does this is called a "boost
converter". Small ones are fairly easy to get (12vdc in, up to 40vdc out
at up to a few amps). Above that, it will take some digging to find one.
