iPad Charger for iPhone?

I tried to change something above but an Apple Error Occured when I attempted to do it... I charge my iPad with my iPhone charger and I charge my iPhone with my PC. Reason being is the PC puts out half the watts,which their is no mention on the iPhone charger how many watts it outputs. Anyone have a clue? I thought it was 5 watts, but cannot find it on the charger or even on the internet.

I know above what I typed gets pretty long and involved, but with all the problems Apple is having from reading all these forum post's I have read and the iPhone 5 being pushed back and stated months ago it would be released May 2012. Well Apple it is May 2012... Wheres the iPhone 5???

Like I said Apple says you can charge an iAnything with the iPad charger and it is your choice to do so and it is safe according to Apple... All their chargers are 5 volts and volts are what would fry out your device if you were to use something higher in voltage. What effect does the iPad charger going to do to your device in the long run? Experience tells me and this high tech charging station I have says charge at the lowest amperage you can for that battery to extend its life to the fullest. Plus lets face it I never had to have a battery changed in a device... What does an Apple Store charge to do that?

From my understanding of electronics (which isn't that of a qualified apple engineer yet much more than of the average person) I can tell you - it will not damage the phone or battery, it should charge a little faster though not at double the rate, and the charge made with the iPad charger will hold for a little less time than the charge made with the iPhone charger, the same with the slower USB charge, it will hold that charge slightly less too, the iPhone charger provides optimal charging conditions for the iPhone, otherwise they would just change it to be uniform with the iPad charger, however among apple's proprietary charge cables for mobile devices there is a mutual compatibility for convenience sake.

I will agree it won't damage the phone because they are both 5 volts. Damaging the battery I have to disagree on for sure. Why did Apple supply the iPhone with a 1 amp output charger? If you purchased an iPhone today does Apple now supply the iPhone with a 2.1 amp charger or the 1 amp charger they always have??? I would have to say a 1 amp but they say a 2.1 amp charger is ok to use but they don't supply the phone with it. I wonder if Apple will release the iPhone 5 with a 1 amp charger or if they will release it with the 2.1 amp iPad charger. I am willing to guess and say 1 amp charger.

I am sure you have seen a motorcycle battery and it is 12 volts and there are 6 cells in it each being 2 volts each to make it the 12 volt battery. If you took that battery and looked at it how thick are 2 1/2 of the cells which would equal the Apple 5 volts? About the thickness of 10 iPhones.

When charging a motorcycle battery would you use a charger made for a car? No. Reason is because it is to many amps and a motorcycle battery requires a 2 amp charge rate, kinda the exact rate of an iPad charger. That is the reason they sell chargers made for cars and for motorcycles because a car charger would ruin a motorcycle battery. They are both 12 volt batteries and that is why they sell a charger for a car (5 to 10 amps) and motorcycles (2 amps).

Apple says its ok to use the iPad charger on all there stuff but car and motorcycle chargers they specify and sell different ones or have a selectable charge amp output selector. Apple says its ok to use the iPad charger on the iPhone but car and motorcycle batteries both being 12 volt require different amp output for charging.

With all that if anyone has a motorcycle battery which charger would you use? Or would you go with what Apple says using double the amperage output on your iPhone.

i plug my ipad2 into the pc cable, "not charging"

i plug my ipad2 into the car charger cable, "not charging"

my ipad2 only charges with the original ipad cable

I would definitely not go for a phone that ran on a lead acid battery. How you look after a motorcycle battery has zero relevence to lithium batteries.

The iPad will not charge via USB from a PC since it requires more power than the USB connection delivers, that's why you see the message "not charging".

The iPad battery is not like a mobile phone battery, think of it more like a laptop battery...

I have to laugh reading the posts from users that acknowledge "I have no idea what I'm talking about, but...".

"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."

The "built-in circuitry" is actally built into the charger.

"If you purchased an iPhone today does Apple now supply the iPhone with a 2.1 amp charger or the 1 amp charger they always have??? <another 100 words regarding the amperage ratings excised>

Apple provides several wattage ratings of power adapters (for iOS and portable OS products). The power adapter is properly sized for the product that is meant to be charged. The most heavt duty portable charger is 85 watts. Gosh, why doesn't Apple simply ship that cahrger with every product? Because it's expensive, and it's cheaper for Apple to R+D several power adapters, rather than a "one-size-fits-all" device.

At least one poster admitted (s)he doesn't believe what Apple has posted on its website, and that's OK.

I only used a motorcylce battery and a car battery as an example due to their size and why they have different chargers for them. I never implied that the batteries in Apple's Devices ran off lead acid batteries, I was just trying to keep it simple. I went to school for all this and I know electronics and all the different types of batteries out their, all about volts, watts, and amps. What charger you want to use it up to you and I just responded to the Apple Post to be helpful, but after this I will not log in again. I will sum up all the above post very short...

Whoever said the iPad will not charge from your computer USB, try this... Write down what percentage it is and plug it in. It will say " Not charging"... Let it sit in sleep mode for a few hours or turn it off and then turn it back on. YES a PC will charge it at a slower rate and compare the first number you wrote down to what you see a couple hours later. Did the charge magically go up or did the PC charge it back up... It is obvious no one wants to wait 24 hours or so for the PC to charge it, but try what I said above and you will see that a PC can charge a iPade despite it saying "Not Charging"...

It is very obvious that the charger has all the ratings on it and it is the regulator in the charger that controls the output. It is clearly on the ipad charger 5 volts 2.1 amps and 10 watts.

If you really want to read all the technical details on different types of batteires Google it. Batteries have improved through the years and soon their will be a better battery than lithium on the market.

Really does it make a big difference what charger you use? NO it does not, but it does effect the life span of the battery. If anyone cares to Google it and read through all about Lithium batteries here are a few things you will see as well, but no one does these not even me... You should turn off your device when charging, not charge up to 100%, not let it run below less than 20%, and if you put an old one in storage everyone thinks you should charge it up all the way. Wrong... It should be charged to around 40%... Google it and see and read through all the technical details of Lithium Ion batteries...

It makes no difference like I said what charger you use... They are all 5 volts and they will not ruin your device. I simplely meant it if you want to extend the life of your battery a slow charge is best...

The above is of course utter nonsense!

What you mean in fact is 20% and 40% respectively of the actual battery charge NOT what is shown on the iPad's battery meter.

They are two totally different things!

And why not charge the battery up to 100%?

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

Yes, a 220V light bulb would definitely light up when plugged into 120V, but it would light up less brightly than in a 220V power source.

You are right about that I was wrong and can admit that about the light bulb and was using simple statements so people could relate to them I could put formulas down, but I was trying to keep it simple so I didnt have to put forumulas down to explain it. Reason being trying to keep it simple so everyone would not be lost...

Now, I admited that I was wrong and not sure why I typed that about the 220 volt light bulb and you said it would be "less bright", and since you are correct and I know why... Please tell me what the output would be and how you came up with that? If you want to throw in the forula how you came to your answer since you are such the expert. Please explain to me how you came up with your answer because you are correct, but you didn't give the exact output other then "less bright", so like I said above please tell me what the actual output would be and how you came up with it. There are about 3 formulas and I never seen the one in school about an anser "less bright".

All I did was respond to a question and offered my knowlege on all the years I went to school learing about electronics and electricity and and I get these comments? Does anyone who responded acutally have a degree in electronics?

Now the person who responded about the why leave the lithium battery stored at 40% and why not charge it up to 100%. Since you just called it "Utter Nonsense" please post why it is "Utter Nonsense". I already double checked on Lithium Batteries and I know I am 100% correct on that, but since you must know more than me and have a higher degree than I do please explain. I will be waiting to see your theory and rationale behind it why it is "Utter Nonsense". Basically, please post the proper way a Lithium Ion Battery should be stored and the rationale why you believe it should be charged to 100%. I will be anxiously awaiting to see your post on why you disagree and call it "Utter Nonsense".

Apple was suppose to release the iPhone 5 I am guessing a year ago... Anyone know why it was not released? Why does everyone complain about the battery life on the Iphone 4S and Apple has released two IOS updates where they claimed to have fixed that issue, but everyone still complains. Does everyone believe what Apple says???

I thought this forum was for helping each other out, but everyone that has replied has turned it into a joke and not one person stated they have a degree in electronics, but they all know the answers. I will be checking this post from time to time and anxiously awaiting to here the responses to the replies that were made backed with proof instead of a one sentence comment...

I will state this once again I simpley stated that in the beginning if you want to preserve and maximize your battery the ideal charging method to do so. I know it is not practical and everyone wants their device charged up as fast as it can so their is no down time. And once again do I practice these principals... NO because I get a new iPhone when they come out. However, the iPad I have I plan on keeping for a while so I will charge the battery the correct way...

Now everyone that posted with all the answers saying I was wrong please post factual information explaining how I am wrong, not just one or two sentence comments. I am 100% sure that you can't because I admited the one mistake I made now please prove me wrong and show the Apple Community how smart you are and please provide the correct answer to back up the comments you made. I am anxiously waiting to see what you write..... But, I know you will not because what I typed is correct.

I can promise this as well.. I will never respond to an Apple post ever again and you can rely on the people who posted replies above for all the answers you need to your questions....

I will check back in a couple days to see why I am wrong....lol....

I'm sure I've read recently that the circuitry is built into the iPad charger to charge an iPhone at 5 but the iPad at 10, and to me that seems feasible.

Are you serious?

Are we discussing rocket science here?

If you plug a light bulb into a power source half the rated input power of that light bulb, it is obvious that the light bulb will light up less brightly.

Hint: light-dimmer.

The actual formula explaining this phenomenon is totally irrelevant for this forum.

My question to your previous claim still remains open:

Why not charge the iPad's battery up to 100%?

How much would you prefer instead?

90%?

95%?

99.9%?

That is exactly what I meant that this forum got way off track. An now you bring up light dimmer? I guess you have absolutely no electrical or electronics backgroun other than turning on/off a light switch or plugging something into an outlet. I do not believe Apple when they say the iPad charger is ok to use on the iPhone but that is my opinion then idiots like you come off like they know everything when they know nothing. Light Dimmer. That has so much to do about this forum.

You are the expert here so why don't you explain all this to everyone that reads this post it is now in your hands since you are the expert, so why don't you answer that one since I am guessing you have some type of degree in electronics.

I have said this now for probably the 5th time. Someone asked a question and I gave an answer based off my knowledge on the charger. Then the Lithium battery came up and I gave an answer there as well

For the answer to what the charge should be why don't you explain it all for everyone to read since you seem to know everything and am leaving that in your hands. Maybe next time when someone puts up a response to a thread you will not come off like a know it all and maybe you will learn something instead of embarrassing yourself by saying dumb things. Now you try to sound professional by saying my previous claim still remains open. Which it will because you can explain it all fore veveryone to read and I myself is waiting to read what you come up with.

So now we are talking about dimmers on an Apple Forum. Lol. You are really BRIGHT

"I do not believe Apple when they say the iPad charger is ok to use on the iPhone"

Yes, but you are very, very wrong.
