    I was wondering if it is ok to charge my iphone with the ipad usb power adaptor which has higher power.
    Or does the default power adaptor for the iphone works for the iPad vice versa?

    Does anyone have answer?

    I don't want to burn my iphone by any chance.

    I heard from someone else that Apple said No. So I wouldn't if I were you.

    If you see smoke, then the answer will be no.

    If Apple sells the iPad with a charging system (cable/plug/charger) that will fit the iPhone/iPod, but damage it if you use it, then THAT would be a major engineering fail.

    10W Supply should be fine with iPhone 3GS

    The differences is the current rating. I have two different supplies for the iPhone. The latest one is the the very small one that does not have the exchangeable AC connector and appears to be quite low power. The first iPhone had a 2.5 W supply that looks identical to the iPad supply but is a 1/4 of the capability. Since the voltage is the same in all cases (5v), they should all work fine, but the iPad will charge faster with its 10W supply and it will probably make no difference to the iPhone. As stated in this thread the fact that all supplies share the same connector means that Apple will not have overlooked the fact that you could plug any other supply into any other device with the same connector and would make sure that no damage would result. Note that earlier iPods, for example, used 12v supplies but the power came in on another pin on the same connector used today. Thus connecting a 12v supply to a current iPad etc. will not cause any damage, they will just not charge or power the device.
