Your new iPad mini will be shipping with a smaller 5W charger. The same charger which Apple ships with the iPhone 5 will be shipping along with the iPad Mini. That’s a bit odd as the battery on the iPad mini is way bigger than that on the iPhone 5. Charging the iPad mini will take longer than charging an iPhone and the 5W charger might not be up for it.
But, that’s what Apple is going to be shipping, so we’ll see and keep you updated.
