I'm not sure where you found that the iPad will take up to 10A when charging, but I am almost certain that is not true. It is pretty much physically impossible for the small iPad dock connector to be able to deliver 10A (that would be 50W because the charger operates at 5.0V). That much current would most definitely melt the connector.
I'm guessing you might have current confused with power here because the iPad can in fact be charged by up to a 10 watt charger (not 10A). That would be 2A because the charger is 5.0V.
As you said, the current capacity of this charger is not listed, but I'm guessing it would be around 500mA to 1A in total for the 2 charging outlets together. This charger is physically quite small, so it would be very hard, if not impossible, to squeeze in a 5V power supply into this thing that can deliver more than about 1A total.
But, no matter what its current rating is, it will pretty much definitely charge an iPad. If it can charge an iPod or iPhone, as it says it can, then it'll be able to charge an iPad because iPads are charged in electrically exactly the same way as an iPod/iPhone. Although an iPad can be charged with a charger of up to 10W, a charger of any power level less than that will also work, just slower.
