    Nah, I think there is a limit to the voltage.

    I believe the phone limits the charging speed even if you use a higher amp charger, it would charge at the same rate and the stock iPhone charger.

    Yes my iPhone charges much more quickly with the iPad charger as opposed to the 5W iPhone charger

    It will be limited (the amount of volts), but it may still be higher than the stock standard charger?

    It will blow up your phone cause the voltage and current is way to high for the iphone to handle.

    I wouldnt do this if I were you

    The iPad charger is allowed for the use with iPhone and iPad.

    It will not do any damage to your phone. The phone can control how much volts and amps are pulled from the charger. Just because the iPad charger is rated for higher amps it does not mean the phone will pull it.

    This has been discussed before. Charging your iphone with an ipad charger does, in fact, charge the iphone faster, with no harm to the iphone. It has nothing to do with voltage but rather amperage. The ipad charger has more amps available, but the voltage is the same. I have been doing this for the last year plus and no damage to my iphone.

    All usb chargers normally put out a voltage of 5v. The difference is in AMPs, as you can see as per output:

    iPhone 5V 1Amp
    iPad 5V 2Amp

    The iPad charger will charge the iPhone quicker than the stock one. You can even charge iPhones with HTC chargers and vice versa as its USB standard output. But always check ratings on chargers and match with recommended specs as mentioned by manufacturers.

    A quicker charge on the iPad charger.. for sure. and slower if used vice versa (ipad on the iphone charger).

    This is my experience as well. I also get faster charges with my U Socket than with the iPhone adaptor.

    I notice if you put your phone in airplane mode it charges quicker.

    Blow up? LOOOOL My mom sometime uses ipod nano 5g charger, basically any charger with a 30-pin to usb wire, is allowed across all iDevices (except iPod shuffle)

    Think of amps in your circuit breaker panel. Just cause an outlet can carry 15-20 amps doesn't mean the light plugged into is using that.

    Some could argue the extra heat from a higher amp charge in the battery isn't good for it. But any difference in life span is minute at best, probably unmeasurable.

    Yes. Much faster iPhone charging with the iPad charger.

    Now, try and charge a new iPad with an iPhone charger. It takes forever!

    Not exactly. Faster than plugging it into the computer, yes.

    However the wall iPhone and iPad wall charger are both equal in charging times for iPhone.

    The iPad wall charger is 2 amps, while the iPhone charger is 1 amp. When plugged into the 2 amp charger, the iPhone will draw only 1 for obvious safety reasons. The iPad will also charge with the iPhone charger but it will take twice as long only drawing 1 amp.

    USB specs (at least on a PC) are limited to 500mA. That's .5 amps. So that's why it takes longest while plugged into a computer.

    Maybe you should try it. I have them both and the iPhone charges much faster with the iPad charger. Now it's the only one I use. :)

    If you want to charge your iPad on your computer, find a program by ASUS, Ai charger. I know it seems le a scam, but it will allow most computers to put out enough amperage to cause the ipad to actually recognize it is being charged and it is not that slow either. It changes some registry keys in windows and works on non ASUS motherboards as well.

    I beg to differ. The iphone charges much faster with the iPad charger than the iPhone charger. I think everyone's assumption is that the iPhone draws EXACTLY what the iPhone charger provides. In practice, though, I think the iPhone has a pretty large tolerance and is capable of drawing more from the 10W charger, and therefore it charges faster.

    Someone time it. From completely flat my iPhone 4s takes 2 1/2 hours to charge to 100% and until the lightning bolt thing turns too a plug symbol. I have a 2a car charger but that's a huge hassle for me to try that lol.

    Sorry but as somebody else has pointed out, this is incorrect. My iPhone charges roughly twice as fast using an iPad charger as compared to the iPhone adapter.

    You may be correct, however I don't notice a difference. Perhaps if someone timed them. Which begs the question, why didn't Apple just use the same charger for each device, or at least release it as a "super fast" iPhone charger?

    No, and i don't think so that there is a big difference between iPad or iPhone charger. Its all depend on voltage. If you want to charge you iPhone quickly i suggest you to turn off your cell phone. It will charge you phone more quickly.
