God Bless the USB

God Bless the USB
Got a spare port? Not any more you don't.
Once upon a time USB was a simple way to connect computers and peripherals. It carried data, was daisy-chainable, and could power devices. Eight years after its introduction, there seems to be no end to its uses, from keyboards and printers to lights and noodle soakers. One of the latest items plucked from the far reaches of the USB spectrum is cup warmer. Take Power from your PC or Mac to keep your hot beverages stay longer!!
Through normal USB 1.1/2.0 port you are able to maintain temperature of the hot beverages at 40 degree after an hour.
