    Hi all. I have an iPad2 and 4S.

    Is it bad for the iPhone's battery to charge it with the iPad's charger? I've noticed the iPhone gets charged a lot faster with the iPad's charger due to the higher wattage, but I'm wondering if that has any ill effects on the iPhone's battery.

    What about vice versa? Is it also bad in any way to slowly charge the iPad's battery with the iPhone's charger?

    Not trying to be lazy. It's just that I don't always have one or the other.

    Bonus question:
    Has anyone ever tried a usb hub attached to the iPad charger and had an iPhone and an iPad charging at the same time? I've been wondering if the iPad's charger has enough juice to actually be able to charge both over night although I'm sure it would take longer than usual to charge either one.

    As for your first question, the answer is no, the iPad charger will not damage your iphone's battery as the iPad charger does not "feed" the device because it allows the iPhone to just draw the amount of power it needs to charge itself.

    And as far as vice versa goes, is an iPhone charger even capable of charging an iPad at all? I thought the amperage was too low. However, I could be wrong.

    And I know nothing about your bonus questions, as I've never tried it.

    The iPhone charger will charge the iPad, but very, very slowly.

    No harm will come to either device.

    Even a 10W USB Power Adapter is compatible with both the iPhone 4S and the iPad. I've always shared them.


    The stronger the flow, the more it keeps your battery alive. It doesn't have any ill effects.

    Just like you can charge an iPhone with a laptop.

    AFAIK, no. I use the same charger for both, consistently.

    Ah thanks guys! Just making sure.

    And yes, I've charged the iPad with the iPhone's charger, but as some mentioned, it takes a REALLY long time. If I'm using the iPad while charging it with the iPhone charger, it does actually go up, but the percentage is like 1% every like 10-15 minutes. Haven't really timed it, but it does do it. Leave it alone all night and the iPhone charger does get the iPad up to 100%.

    Well, this whole time I had no idea. I will remember that the next time my ipad is dying and all I have is an iPhone charger available.

    I use the iPad charger for both and haven't had any trouble.

    I use the 120v connection for charging. the iPad needs 10watts. I don't know id you can get that with a USB connection.

    I use my iPad charger for both all the time. It works great and I enjoy the simplicity of only using one charger.

    If you use the iPad while charging it with the iPhone charger the power supply might not be enough to keep it afloat... So it might be best to turn the iPad off for fastest charging ;)
