The manufactured cost of that cable is close to a USB cable. To give them the benefit of the doubt lets say it costs $5 and they sell it for $40 provides them an 87.5% profit margin.
As for Resmed at least they have a boost converter in the cable.
Comparing a USB cable to a 16 ga wire assembly is like comparing a dad-gummed Toyota Prius to a Kenworth tractor. It is just silly. Following the USB logic, we could just a easily say that the main lines bringing power off the transformer to the house is a USB cable. Enough of that nonsense. If you want to draw a comparison, an extension cord would be better than a USB cord. But it would be a fancy extension cord. So what if the cable is cheap to manufacture? I bought one and sent it back because I thought it was a stupid design anyway.
And rather than praising the overpriced Resmed piece of, well, fertilizer (which also probably has direct costs of less than $10 to manufacture), the question should be "Why the frack does Resmed make products that require one? And when they do, why do they add insult to injury by requiring that you buy their stupid cord with their stupid box with the 'boost converter'?"
