They claim their USB power adapter provides enough power to charge the iPhone and the iPad at the same time. Outputting 3.5A on one USB and 2A on the other. I wonder if it’s a mess all the different power charging of USB cables, that some USB power sources output more power than others, that some USB cables transport more power than others, and that new USB charging devices such as the new iPad having such huge batteries that take over 10 hours to fully recharge over a normal USB cable, but which may or may not charge faster when using a more powerful USB power source and USB cable.
