I would assume no because Apple sells that Dock kit with it, and I notice I get a better charge with the iPad charger, however I am wondering if anyone has run into trouble with it before?
 
I used to do it sometimes then I realized the iPhone gets really hot due to the iPad charger pumping higher voltages. So now I just charge my iPad on my iPhone charger instead even though it takes a little bit longer :eek:

As for the dock charger it isn't such a big problem because the dock itself uses power.
 
I used to do it sometimes then I realized the iPhone gets really hot due to the iPad charger pumping higher voltages.

iPad charger output is 5.1Volts, 2.1Amp. iPhone charger output is 5Volt, 1Amp. So the iPad charger is a higher output voltage, but only 2% higher. These are what's written on them, I've not put a meter to them to verify.

Since the voltages are essentially the same, the draw (Amps) would be dependent on the device being charged; I doubt the iPhone would take a damaging current level for charging -- thus it should be perfectly fine unless you're using a thick case that holds in the heat.

With that said, since I tend to charge both devices overnight while I'm asleep, I have both chargers set up at my desk and plug each into its own charger. I've used the ipad charger while travelling with no adverse effects.
 
Good to know, now I wonder if I buy a Chevy Volt if I can charge it with that adapter as well :D

Thanks for the info all
 
The iPhone draws power from the charger, the charger does not pump out power. Charging from the iPad charger will not hurt your iPhone.
