Tractor Supply or Northern Tool?

Also, copper clad aluminum is the suck.

2 gauge aluminum is more than adequate for jumpers.

2 gauge aluminum, 20 feet, 600 amps (typical jump requirements) nets a whopping 45% voltage drop across the circuit... so you're trying to jump start a car with about 7 volts. Math.

Also, come by and try jump starting my vintage diesel 4x4 DD. Your cables will melt into a puddle.

You don't buy 2 gauge for starting a normal car so this is a scam to screw over people. this will lead those with high power trucks/diesels with a possible fire as the cable melts. CCA for this application should be made illegal.

Nobody is melting these. They may not work for a diesel with a battery with dead cells but they'll crank it fine with a flat battery.

I'll trust your math on the voltage drop, however that would be assuming that all of the power going to the starter is flowing through the jumper cables. In a typical jumping scenario, the "dead" battery can contribute quite a bit, especially after receiving a brief charge from the other running car.

I'd personally shy away from such long cables due to their inherent resistance, but aluminum is typically fine if sized right. Since it doesn't conduct as well as pure copper, just get a larger gauge cable and it'll still probably be cheaper.

Some folks are too stupid to understand they are stupid. Cars do not draw 600 amps. They draw about 125 to 225 amps depending on whether a 4, 6 ,or 8 cylinder. 200 amps is about a 2 volt drop across the jumpers and should be fine. If the jumpers are used to assist a weak battery, the voltage drop will be even less.
2-gauge aluminum is equivalent to 4-gauge copper. 4-gauge copper jumper cables would be considered as a good set of jumpers.
I have jumped vehicles using 18-gauge wire. You just need to know what you're doing; mainly the condition of the battery that is weak.
