Is it safe to do so? I'd like to carry only one charger.

    my experience with electrical devices is to always use the correct charger to charge your device. the ipad charger is a 10v charger while the iphone charger is a 5v. so use a 5v charger for your iphone and 10v for your ipad. i read a couple of threads where users used a wrong charger and it burnt out the ops iphone.

    If you use only one charger, use the iPhone charger...better a slow charge on your iPad than a fried iPhone...

    I'm sorry but you are wrong.

    Both chargers are 5 VOLT. one is 5 watts and one is 10 watts. These are based on maximum amperages before the voltage drops. If you put an iPhone on the ipads charger it will see 5 volts as it always does. It has an inherent internal resistance and will draw a specific amount of amperage and hence power from the charger.

    So Joshua, you are saying that it shouldn't be a problem to use the iPad charger with an iPhone 3GS?

    I thought so, but wanted to double check.

    Thanks.
