Audio Magic power cords

Does anybody have information on Audio Magic Black Thunder power cord? Not to be confused with Straight Wire's Black Thunder. I have tried several times to get The Cable Company to correct their listing for the Audio Magic cord, but to no avail. They still have it listed using Straight Wire's description for their copper cord, rather than anything from Audio Magic, which uses silver wire. I'd sure like to know the construction features, especially gauge and shielding. I know it's confusing; both companies offer a "black thunder" power cord. But you'd think the a company like The Cable Company, which specializes in audio cables, could publish accurate information. And oddly, Audio Magic has zero information on their website about any of their cables. Any helpful information about this particular power cord would be much appreciated.
