iPad Charger for iPhone?

It should. and it works quite well. I use my iPad charger on my Touch all the time

Yes, the iPad charger is 10W & the iPhone charger is 5W, so it will charge faster, but not overcharge.

 Cheers, Tom 😉

I am probably wrong, I know we can mix/change current (mah.) to charge a device faster or slower, i.e. 700 mah would charge slower than 1000 mah keeping the same voltage, but I wouldn't charge an Iphone which works with 5W thinking it would charge faster using a 10W charger. I never tried before but normally doubleing the voltage would fry the power regulator in any device.

It's not a doubling of the voltage - they are both putting out 5v. It's a doubling of the available amperage.

It works perfectly fine with the higher power charger. The voltage remains constant at 5 VDC. The available current is higher, and any device that requires a 5 V charging source will only utilize whatever current it requires, and no more.

Also devices only take the amperage that they need

The voltage is the same, it's the amperage that differs. Therefore it will not fry the iPhone.

If the amperage was way higher, it could damage it anyway, most likely due to overheating, but since people are doing it succesfully it's obviously no problem.

Ok, that's good to know, now I can use my car/home chargers to both my Iphone and Ipad. Thanks for the info 😉

The store that I bought my iPad and iPhone in (SoftBank Roppongi, Tokyo, Japan) actually advised against this as it can potentially ruin the phone's battery.

And Apple recommends it for the iPad and iPhones. I'll believe Apple.

I would also like to believe Apple as it would make my life easier. Do you have a source to back this up?

Look it up in the Apple Store and see what they show it as compatible with...

Yup!

Great. One less cord in my bag!

According to Apple just like stedman1 said above and the link posted the iPad charger is compatible with charing iPhones, Itouch, iPod, etc... They are both 5 Volts and if you were to use a charger with a higher Voltage Rating you would fry it out that is for sure.

Example 1... If you took a light bulb that is 120V and plugged it into a 220V outlet it would burn out instantly.

Example 2... If you took a 220V light bulb and tried to light it up with 120V it would not light up.

Their are ways you can make things work of different voltages with series and parallel circuits, but thats really not what this discussion is about. I know personally I can take 600V and make Five 120V light bulbs light up and they will not fry putting them in a series circuit. If I wired them in a parallel circuit they would fry instantly. Thats as far as I am going with that because it will get way to confusing...

Here are the 3 main concerns of the Apple iPad and iPhone Charger:

Volts: Pressure of electricity

Amps: Volume of electricty

Watts: Amount of electricty

Both Chargers are 5 volts so we all know that Voltage is fine and no worries their. From reading somewhere and I don't have a clue where it stated that the iPhone has built in circuitry that allows the the use of the iPad Charger on the iPhone just like Apple's website does. Is it true? I don't have a clue, but I do know if you plug your iPad charger into any iPhone, Itouch, iAntything, it will charge it. What effect is it having on the battery, I don't have a clue but with it being higher Amps it is putting more of a volume in and higher watts it is putting more in.

I know Apple says its ok, but personally I do not trust it and I will charge all my devices with the proper charger because I do not like fast charging and not sure if what I read about the circuitry is true or not. I know everyone wants their device to charge fast so they do not have to wait, charge it up and get going.... I prefer slow charging because from experience with rechargable batteries fast charging a battery they do not last as long. When you slow charge a rechargable battery you will get more charges out of it and it will last longer. Reason I say this is I do not purchase regular batteries for any electronic devices I own and have a pretty high tech recharge station for these batteries. It states right in the manual you can charge your batteries faster with more amps, but your rechargable batteries will not last as long, and if you want to extend the life of your batteries the lower the amperage the better.

That is why I am skeptical about Apple saying it is ok to use the iPad Charger on the iPhone, iTouch, iAnything... I typically charge my iPhone with my PC that produces the 5 volts, but it is only outputting .5 amps which would be a slow charge. With the iPad when you plug it into your PC it shows "Not Charging" because with the display on it is not enough amps to charge your battery with the display on.

Try this.... Plug your iPad into your PC and see the "Not Charging" on the iPad, write down what percentage it shows your battery at, let the display go off and let it sit overnight or even better turn it off. When you turn it back on in the morning will your battery have charged? YES.... But very, very slowly because the PC is 1/4 of the amps the iPad charger outputs. Lets face it the iPad has a big battery compared to the iPhone and the iTouch, so it needs more amps and watts to charge it up. How could Apple say use your PC and it would take a day to charge up your iPad???

Bottom line is Apple states it is OK to use the iPad charger on your iAnything.....

Me... I am putting my iPad chargers to the side and only using them when I need the iPad to charge fast and will charge it with my iPhone charger and let it charge at a slower rate because I know it will extend the life of my battery. If Apple put something out which if they did I cannot find that the iPhone has circuitry to have a cut off I would do it, but I am sticking with my iPhone Charger for everything.... Personally reading all the posts on this forum Apple has a lot of people complaining about a lot of things. Plus I recall reading that the iPhone 5 was to be released in May 2012... Well, its May 2012 and no mention of the iPhone 5...

You will be fine charging your iPad with the charger they provided, but like I said above me personally I charge my iPad with my iPhone charger and my iPhone with my PC because it is 1/2 of the amps and doing that creates a slow charge which I know for sure is better on rechargeable batteries and they last longer.

Once the iPhone 5 does finally come out I know I will pre-order one, but at this rate with Apple it is years away and don't really feel like putting a new battery in my iPhone 4s..
