    I must correct and update the other answer that was posted for this question.

    Apple now sells USB power adapters in 3 wattages:
    - 5W ships with iPhones
    - 10W ships with old iPads
    - 12W ships with the latest iPads

    It is the adapter (the block that plugs into the wall) that determines its wattage and voltage. The cables are completely interchangeable with anything that it fits.

    As new devices step up the wattage from 5, to 10, to 12, Apple has created adapters to help them charge more quickly. All of the adapters are backwards and forwards compatible (they all "work" with older and new devices). However, charging an iPad that came with a 10W adapter with a 5W charger will be very, very slow. But it works.

    Here is the correction to the previous answer: Charging an iPhone (usually a 5W device) with a 10W charger will NOT charge it any faster. It won't harm the phone either. The charger simply steps down the wattage for the device and charges as it a 5W charger would.

  • It is the adapter that determines the wattage of the charger. The cables are completely interchangeable (with the exception of the new lightning connector for iPhone 5).

    You can charge both the iPhone and iPad with the iPad adapter.

    It is recommended that you use the iPad (10W) charger to charge the iPad.

    That being the case, is there a charger on the market with two USB ports so I can charge both my iPhone 3GS and ipad Air simultaneously. I would just love to travel light with one charger, also time is an issue so a charger as described would be a real blessing.
