I actually use my wife's iPad charger which also supplies 2 amps.
My 7" KFHD does charge pretty quickly with 2 amps but I have never actually measured how long it takes to charge from zero.
I too use my iPad charger and it charges fairly fast. My cellular phone charger is 1.8 amps and charges about as fast. Certainly no reason to pay Amazon for an overpriced item which should have been included!
