Among several new peripherals introduced by Kensington this week, there's one that caught our attention as being attractive for iPhone, iPod touch and iPod nano users. It is a docking station that will not only charge your Apple device, but powers up a second battery at the same time. The Kensington Charging Dock with Mini Battery Pack's second battery promises to extends play time up to 30 hours of music; 6 hours of video; and 3 hours of talk. Not bad. Available for pre-order, the device goes for $69.99. See here for more information.
