So Amazon gets to be the sole distributor of printer paper, the manufacturer is some old growth harvestor in the Amazon using prison/slave labor for harvesting/processing, and even then you’re paying more for a worse product than when a well regulated and unionized workforce was producing the commodity a decade earlier.
That doesn’t really make sense in this context as this paper is made by Canon not Amazon. You could make the argument that Canon is using rainforest paper, but then the rest of this kind of falls apart.
5A is the max rating for USB-C. What you’re looking at is probably a 5A cable with a “10A” molded into the connector in true sketchy knockoff fashion.
To answer OP, USB-C connectors are often used outside of phones/tablets like with hobby electronics like boards to control LED strips that could benefit from more current. Unless this cable is super thick, there’s little chance it can actually handle 10A and even if it can, the connectors aren’t rated for that much current.
