Kensington PowerBolt Duo: Dual USB car charger for iPhone, iPad, iPod and other USB devices, 2.1A 1x, 1x 1A (Electronics)
What should I write?! Perfect !! The unit has 2 ports, one with 1A and 2.1A with power. My iPhone 4 and my iPad is loaded on both ports (yes, even the iPad at the 1A port), even if 2 units are connected. So strong buy recommendation.
