Confirm a noticia Not too positive, and that is that the iPad mini unfortunately does not come standard with the 12W charger of the fourth generation iPad that allows to shorten the charging times, and neither does it with the 10W of the previous iPad ... but it brings the one of the 5W iPhone.
At the moment it has not been revealed if the cause of this is that the battery does not support more than 5W when charging, but in the case of a battery of more than 4000 mAh I think it will allow the use of the 12W charger.
Charging the iPad mini could take approximately 4-5 hours with this charger, while if it carried the 12W it would take 2-3 hours at most, a substantial improvement.

Well, it is clear that the 12W or 10W charger of the previous iPad should work with the Mini, because most of the time I charge my iPhone 4 with the Ipad charger and it charges perfectly and nothing happens to it.
