All but lost in the shuffle of major new Apple product releases this week was the new 12W USB Power Adapter, which as noted in our earlier story is designed to work with iPads and a number of other recent iPod and iPhone models. The 12W Adapter is an updated version of the 10W USB Power Adapter shipped with all previous iPads, and will be bundled with the fourth-generation iPad and iPad mini, as well as purchased separately for $19.
According to 9to5Mac, Apple has confirmed that the adapter will charge previous iPads faster than the older 10W adapter, stating that “[w]e don’t have an exact percentage of how much faster it would charge but you should see an increase in speed.”
Calculations run by iLounge suggest that the 12W Adapter could shave off up to two hours of charging time for the third-generation iPad, which notably took 7 or more hours to refuel. It’s unclear how much of an improvement will be seen by older iPads, as well as the iPad mini, which has roughly one-third the battery capacity of current full-sized models.
