I've been looking into this a little bit, and I came across this site: http://androidforums.com/samsung-galaxy-nexus/464642-all-usb-charging-cables-same.html
There's a guy who claims that he had a cable that could only support 500 mA. He says he put more current thru it, and it melted. Not sure if that's for real, but it sounds theoretically possible. Thanks.
