Billed as an iPhone audio amplifier that requires no power, iKit's NuFlow ($40) is a hollow plastic shell with a speaker grille on the front and a mini USB port in the back. Holes in its iPhone dock enable it to pass any iPhone's sound into its amplification chamber, achieving a volume increase of "up to 10 decibels," while a USB cable and European-only wall charger are included if you want to sync and/or charge the iPhone inside. It's also capable of being turned on its side with the iPhone plugged in to perform in widescreen mode.
