A while back I purchased a 12V air compressor which is useful for tires and other things. I also have a compressed air tank it is useful for filling that. The cables where short and light gauge wire, plus you had to lift the hood to put the clamps on the battery. I put a 175A rated quick connect on a 150A fuse reachable under the front bumper. I made a short 175A to 50A connector and then an AWG 6 gauge cable with 50A connectors. I had some odd 35A rated connectors from older UPS batteries so added one to the air compressor and made a 50A to 35A short step down cable. No excuses for underinflated tires.
