    Saw the 4th Gen iPad. Got pissed off. Then started using my 3rd gen again and realized there isnt one bit of lag in my ipad 3 - i use it for web browsing, dropbox pdf viewing and ibooks.. I dont game apart from fifa 13 and i have a feeling that since the mini ipad and the ipod touch are still A5, my ipad's chip wont get 'obsolete' anytime soon.
    so now I'm over it. But.... I saw that there is a new 12w charger. I realized that the current one is 10w. how much faster will this new charger charge my ipad? Any electrical engineers out there? worth the $20?

    12W charger will charge in 40% less time than the old 10W charger. :)

    most useful response of the year! dont you have better things to do than be an internet forum janitor??

    ps: i kid of course....

    EDIT: cool!
    I know Ohm's law:
    V = I x R (just from high school days.... ) of course that doesn't take in any consideration on time. but is there a formula/some physics principle that would calculate that?

    Will this charger be compatible with the ipad 3?

    Not sure if serious, but...
    If the iPad 3rd gen is compatible, it will charge 20% faster with the 12 watt charger.
    As the battery has a 42.5 Wh capacity, theoretically it will charge in 42.5/12 hours (if you ignore power inefficiencies such a heat etc.), compared to 42.5/10 hours with the 10 watt charger.

    A little off topic but, do you think this charger can be used on the iPhone 5 and if so, should it charge that faster?

    Now I have to wait for a car charger that will handle two Lightning connectors.

    Yes this 12w charger is fully compatible with iPhone 5 and ipad 3/4th gen.

    I just placed an order for one of this. Apple has agreed to fully refund me my purchase of the older 10w charger which arrived ONE day before the new product was up

    I actually was serious .. thank you. now technically then shouldnt the iphone charge faster with the ipad charger? as mentioned above? and what stops people from making say (an exaggeration) a 100w charger to instantly recharge the battery?

    The answer to your first question is that the iPhone 5 decides what the maximum current is that it can draw. It may be 5 watts (1 amp at 5 volts) or it may be 10 watts or 12 watts (2.4 amps at 5 volts). iPhone 4Ss charge faster with the 10 watt wall charger - I expect the iPhone 5 will too. The batteries have a limit as to how quickly they can take a charge - that is why a 100 watt charger would be redundant - the iPhone would still only draw perhaps 10 watts.

    The answer to your second question is that there are many car USB chargers already on the market, with one 10 watt and one 5 watt USB outlet. Both outlets will handle a USB to lightning cable. MacNally even have a dual USB car charger with 10 watts output on each USB port.

    I believe it's the size of the "brick". In my observation, PC charger bricks correlate to their wattage - at least in the 45W to 120W range. The correlation could be non linear on either side of that band.

    The one I want will be able to charge the iPhone 5 and iPad 4 and come with a plug and two Lightning connectors so the other two can stay at home for charging there.

    I wonder if the mini or the iPad 4 will come with the 12W charger.

    Apple's "what's in the box" shows the Mini getting the iPhone Power Adapter.

    From what I understand about the power management in the iPad 3, a bump of 2w will not matter.

    I'm just going by the picture Apple put on their store. It shows the iPhone adapter.

    The question would be whether the 3rd gen will actually use the full 12 watts over the 30 pin cable. The Lightning connector can dynamically switch to use all of its pins for carrying power, so it may allow more charging current than the 30 pin.

    In the Apple Store app. They don't show it on their website.

    They show the same thing for the retina iPad, and I'm pretty sure that's not what will come with that product.

    Do you guys think the Charger will come with a 6 foot long extension cable?

    I asked my local Apple office and the CSO confirmed multiple times that it was included in the package, BUT the Apple Store page does not list the extension cable.

    What's in the Box

    iPad 10W USB Power Adapter
    Apple Dock Connector to USB Cable
    Apple power cord (6 feet)

    vs

    What’s in the Box

    Apple 12W USB Power Adapter
