    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?

    The connector is universal. Scroll down a bit on this page to see the compatibility.

    I've used my roommates on my 4 and neither of us have experienced any pain.

    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.

    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.

    Yes I have no symptoms of pain either. But a little Ibuprofen will definitely help if one does.

    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.
