As I said in previous threads, while these are vaporware, if you need a real device from a reputable power supply company then the FSP Twinkle will do: http://www.fsplifestyle.com/product.php?LID=1&PSN=771 it's not Mac compatible and there are no USB ports but unlike these companies, FSP is the real deal, it's the 5th largest power supply vendor in the world. I am not a shill for FSP merely a very happy Twinkle user.
