You must hear this name: Griffin but now I am not talking about that big guy. I am talking about a dual usb slots car charger and usb cable set for you Apple iPhone 4. Griffin PowerJolt Dual Micro provides fast charging for almost any device that charges via a standard USB connector. Use the included cable to plug your device into either of PowerJolt Dual USB ports. Use the other port to charge something else at the same time. Self-resetting SmartFuse circuit protection means no blown fuses to replace. You can have a look at it now on:
