    And the answer is, and always has been, yes you can use the iPad charger to charge the iPhone.

    This is an absurd thread. People are so caddy.

    So charging my iphone with the 12w charger won't do battery damage?

    I normally don't feed trolls but the timing made me laugh. Here's a cookie.

    You don't seem to know what you need. First you want it is done and you don't want to be notified, then you want it to continue. Make up your mind.

     

    Then you seem to indicate you don't care what the findings of Apple's engineers, with the approval of Apple's lawyers (they work for Apple, just like the engineers) say, you would rather trust some unknown person out there to make up your mind.

     

    OK, here goes. I've interchanged my iPods, iPhones, iPads charging since I first got the iPad 1 with the 10w charger. It has not harmed any of the devices and I haven't found anything weird.

     

    Just like the engineers and lawyers said

    Perfectly safe, but I wouldn't trust it to power the ECT machine you seem to be in need of.

    Hello, I was given a "Power Bank for iPad/iPhone" .

    Capacity:  5000mAh

    Input: 5V, 1A

    Output1: 5V, 1A

    Output2: 5V, 500mA

     

    By your post of May2 @ 10:15 it would appear that the output port I should use for iPhone5 is Output 1, but to charge my iPad I would need 2.1Amps.  My assumption is that I would also use Output1 for iPad, but it will take longer to charge than if I had a 2.1A Output port.  Is that correct? 

     

    What device is Output2 port good for at 500mA?

     

    Thank you

    I should say that this is a portable charging device

    Output 1 is for the iPhone and will also charge your iPad, but take twice as long. The second USB port can be used for charging lower powered devices, such as BlueTooth headsets. That specific device can charge 2 accessories simultaneously, which is why it has 2 ports.

    Simple answer as to why iPhone gets hotter while using iPad's power supply to charge it:

     

     

    Imagine you have to move a bunch of wood from pont a to point b and you can only carry so much wood per trip. you can either do that by:

     

    1. Walking from point a to point b while carrying the wood.

     

    2. Running from point a to point b whle carrying the wood

     

    With option 2 you will take the wood from point a to point b faster than with option 1. But also due to the elevated physical effort you will get hotter, which will make you sweat, which in turn will make you feel tired faster.  You carry the same amount of wood in both options and the same amount of wood per trip. It's not the added capacity in the iPad's charger that kills the iPhone battery but the extra heat generated by doing the same job faster.

     

    Sorry I tried to explain it this way but I have no tech background whatsoever but this is how I understand it.

    Well, you understand wrong Rob. As has been stated several times in this thread - charging your iPhone or iPod with a 10W iPad charger will not overheat the battery, cause it to charge faster, or do anything any differently than charging it with a 5W iPhone/iPod charger.

     

    I have been charging my iPhones (first my iPhone 1, then my iPhone4) on my origina iPad charger since I got my iPad in 2010 when they were first introduced. It makes absolutely no difference if I charge it using my iPad charger or my iPhone charger. They work identically in terms of charging the iPhone.

     

    Your illustration does not accurately demonstrate the concept. Think of pulling a rope straight up through a tube. If the tube is the correct size for pulling the rope up at maximum speed, you would not be able to pull it up any faster if the tube was larger than the size you needed to pull it up that speed. i.e., 10W tube with 10W pull vs. 10W tube with 5W pull. The rope isn't affected, your ability to pull isn't affected, the amount of energy you expend pulling isn't affected. End result: exactly the same....

     

    There is absolutey no difference, no negative affects, no reason not to use the chargers interchangeably on an iPhone or iPad.

     

    Cheers,

    Sorry - last sentence should read - iPhone or iPod....

     

    If I'm remembering correctly, using the 5W charger for an iPad slows down the charging time so it will take longer. Using a different analogy for this concept - a gallon of water will take twice as long to go through a 1" tube than it will to go through a 2" tube.....

     

    Cheers,

    Didn't you read what I said???  It's not using the iPad's power supply what kills the iPhone battery but the extra heat generated by a faster charging. Read it again, understand it and then come back and reply.

    Do you think the 100s of people coming asking why they notice their phone charging much faster or why their battery is draining faster after using the ipad charger, is in their head? Dont you think maybe just maybe after the 100s person searching for this that maybe what they are reporting is of some significance and not be so arrogant.

    People find this thread and fall victim to the arrogant stuborn folks as yourself after google provides them this thread as top choice.

     

    From my experience and is how I found this thread after a google search and why more keep falling victim to this pathetic thread and to all people noticing strange behaviors using their ipad charger.

     

    Yes the ipad charger charges the iphone much faster then the iphone charger.

    Yes you will notice the battery dranining much faster after using the ipad charger.

     

    It is not your imagination and disregard these clowns here telling you its your imagination.

    It does not charge faster, it does not get hotter. It charges exactly the same regardless of the charger wattage....
