Has anyone been able to find any documented info (other than word of mouth from apple "genious's") on whether or not its safe to use the Ipods charger? Thier Voltage output is 10V, whereas the Iphones charger has a 5 Volt output. Thats quite a differance there, and it strikes me as odd that if it is bad for the Iphone, why they say "Ipod accessories MAY not be compadible" MAY is the key word here....as in...your Iphone MAY be damaged???
And DOCUMENTED info please???

    i have never thought of that. Now you have me worried.

    I was told by a an apple store guy that you should check the ipod charger before you use it with the iphone. Older ipod chargers have different voltages. He said that the color screen 4G ipods and 5G ipods should have all come with the 5V chargers at 1amp. If the charger says something else on the bottom then he said you run the risk of damaging the iphone and should not use those chargers. They might still work but there is that risk there.

    The chargers that ship with the iphone actually say ipod charger on them.

    Seems like it would be safe to use the same charger for both iPod and iPhone -- I've been doing that for 2 months with no issues so far.

    Here's the description of the Apple USB Power Adapter that I've been using, as shopwn on the online store:

    *Apple USB Power Adapter*
    +Use this compact, convenient USB-based adapter to charge your iPhone or iPod at home, on the road, or whenever it's not connected to a computer+

    The new adapters that apple sells are made for both. The old chargers output at 10V which is 2x what is needed now.

    You can do a simiple experiment to see the damage using the wrong voltage charger will do. Find 2 cheap items that use different voltages on their chargers, that you could potentially use on both. Plug the high voltage charger into the device that normally uses a lower voltage charger. Within a few mins it will probably start smoking and such. I have seen this happen, I even ruined a printer one time because I plugged in the wrong power adapter and within 5 mins smoke was coming out of it. Sending the incorrect or too much voltage to a device can damage the internal circuits if they are designed to handle the added voltage. Newer ipod chargers run at 5V, like I said the bottom of your iphone says "ipod power adapter" on it. Apple sells the same thing for both so if you have a 5V ipod charger you are fine. I have one that came with my old 4G ipod that says 5V on the bottom and I use it. I would not use one that says something different. Yes it may work, but there is always that one time something will go wrong and then you have a $500 paper wieght because I doubt apple will cover you using the wrong charger.

    There is only one USB port that charges both the iPhone and iPod - USB 2.0. The port doesn't distinguish between iPod or iPhone, nor is there any kind of switch (software or hardware) that is used to detect/differentiate between iPod or iPhone. Perfectly safe to use the iPod charger for the iPhone and vice versa.

    So I guess I shouldn't be using a car charger that I bought from some street vendor last week.

    What about other accessories for earlier iPods?

    For instance I have a car stereo that allows me to plug in my ipod in the glove compartment and works great with my iPod mini. When I tried my iPhone on it, the iPhone displayed the message "this device not designed to work with iphone" or similar. But it worked ... albeit at a lower volume than the ipod.

    Same thing with a Klipsch stereo player built for iPod. Again my iphone fits it, but complains.

    Are both of these devices shoving double voltage up my iPhone?
    I would have thought there would be more publicity on this.

    I guess no one is still understanding. No one is saying you can't use an ipod charger with the iphone. I am saying make sure that it says the correct voltage on the bottom. The chargers you can buy right now for iphone/ipod are the same thing. Chargers sold with color 4G and 5G ipods are also (should be) 5V chargers. Older chargers with non-color 4G ipods and older output different voltages. Yea they can work but you are taking a risk of damaging your phone. My bro has a charger with his old 3G ipod that is firewire. That charger says 10V on the bottom. Now he has tried to use my newer ipod charger that is USB and 5V, and it doesn't work, not enough voltage is going to it to charge. Going to the iphone it is now sending 2x the voltage needed, sure it probably works. But there is RISK of that extra voltage damaging the circuits.

    If your car is supposed to use 10W-40 oil in the engine would you put in a higher one? or use 10W-30 in that? NO, you will ruin your engine. Why would you risk using an incorrect voltage charge with your iphone.

    You can use NEW ipod chargers that are 5V, the iphone ships with an ipod charger come it isn't that hard to understand.

    This is exactly what I am trying to get at here. I know that you cannot use a 10V charger on an Iphone that is only suppose to recieve 5V...And older versions of Ipods where 10V is being used, means not only Ipod chargers, but Ipod interfaces....the ones that CHARGE your Ipod at the same time, are charging your Iphone at 10V. So it surprises me that all you see from Apple is that your device "MAY" not work properly. Well of course it wont work properly, you just cooked your Iphone (after extended use).
    Unless the Iphone is designed to accept 10V. So thats the question here... is it?
  • sys3175 Level 1 Level 1 (35 points)
    The answer is quite simple. If you are using any ipod charger in which you attach the USB cable to it in order to charge it, the output of the cable will be no more the 5volts. If the charger claims to output higher then that it may be using more then one conductor. This shouldn't be a problem as the pins wouldn't be there to make contact in this case.

    No apple branded charger will damage the iphone.
    No USB device can require more then 5.25volts (the max on the standard).

    Poor analogy you cannot damage a car that should have 10w-40 with 10w30. That is absolutely redicoulous.

    Any charger which is USB will work.

    Any changer which is firewire (4g non-color or older) should not be used with any newer USB model.
