A thicker gauge like 12AWG has lower electrical resistance compared to thinner wires (e.g., 16AWG or 18AWG), which means less voltage drop, more efficient current transmission, and significantly reduced heat generation — especially important for high-draw devices like car refrigerators and portable freezers running for extended periods.</p> <h4>Q: Is this power cord compatible with both 12V and 24V vehicle systems?</h4> <p>A: Yes. This 12AWG heavy-duty vehicle extension cord is designed for use
