Griffin"s best-selling in-car power and charging solution for iPod and iPhone now works even harder with TWO USB outlets. PowerJolt Dual charges any two USB-rechangeable devices safely, quickly and up to twice as fast as other car chargers. Use one port to charge your iPod, iPhone or other iPod model with a dock connector safely and quickly. Then use the other for any other USB-chargeable device. Comes with a detachable USB to 30-pin dock connector cable that can be used separately to connect your iPod or iPhone to your computer. To charge other USB-charging devices, just use the cable that shipped with your device and plug it into either of PowerJolt"s industry-standard Type-A USB ports.
