I am pleased with the 20-foot 4 Gauge jumper cable set made in China by EPAUTO. The cable is copper coated aluminum, known as "CCA.” It took microscopic examination to see the aluminum core in the fine wires forming the cable. I measured the resistance using an Agilent 34401A 6.5 digit bench multimeter in 4-wire resistance mode to be about 0.4 ohm per 1000 feet which is appropriate for #4 copper coated aluminum. This is equivalent to #6 copper. I was hoping this cable was 100% copper, but it was not advertised as such. It is not likely that any jumper cable in this price class would be 100% copper. The storage bag supplied with the cables is too small. Unlike others, my review is truly honest as I paid full price for this item and did not receive any discount for my review. Compensated reviews are influenced reviews.
