Media event set for September 9, launch likely ~10 days later.
Scosche Already Designing New Dock Connector Accessories
The products appear to come from Scosche and incorporate both a micro USB plug, as well as an adapter for the new iPhone dock connector.
The charger will presumably charge devices that use either the micro USB plug or Apple's new dock connector. The new smaller dock connector has been rumored to be replacing the current 30-pin connector. Photos of the new dock cable have already been leaked. 3rd party accessory makers appear to already be working on compatible devices to be able to provide accessories at or near launch.
