Although the iPad charger is 5V / 2.1A, the iPhone can only accept 5V / 1A so it should automatically limit the intake.
But I just want to make sure, any idea (with source please).
Thanks for the quick answers, but would it harm the battery to quickly charge it or overcharge (leaving it overnight) ?
So if the battery charges faster and isn't harmed in the process, why doesn't Apple have a single charger for all iOS devices? Wouldn't a single charger SKU be cheaper for Apple?

Two reasons why:
1. Portability
2. Profitability
Charging faster will increase the heat which will lower the battery's long term longevity.

Can't remember where I heard it, but I heard the iPad charger doesn't charge the 6's any faster. Can anyone confirm?
