electrical question

As long as the cable is big enough to run the amps that the compressor draws.

Mine drags 30 amps Max, but there are many types of compressor around so don't know about yours..

I use mine with anderson plugs and can plug it into the caravan, or the tow vehicle.

I also have an extension lead with anderson plugs, makes it easy to reach bits and pieces needing 12 volts.

Another thing that can certainly help is to have your engine running while using the compressor, probably with the revs upped to above idle. This will raise the battery voltage a couple of volts, which will reduce the amperage demand at the compressor and cause it to run much more efficiently (if the compressor requires say 48 watts it will draw 4 amps at 12 volt but only 3.42 amps at 14 volts).

i used to run my compressor off of an anderson plug in the back of my vehicle, i just cut the old aligator clips off and put an anderson plug on the compressor and never had any problems. only reason i've stopped doing it now is because i have air lockers and use the compressor from that to inflate tyres now.
