What is the USB port designed for?
The USB port is a standard 5V USB port but contains no facility for data transmission. It was included so that small lamps, fans and other similar devices (originally designed for laptop computers) could be utilized on the bedside. The USB port may be able to be used to power and/or charge some PDA and/or cell phone devices however since there are so many different devices on the market AI makes no specific claims regarding use of the USB port for these purposes.
