Our initial look at the iPad Air 2 reveals that Apple is bundling a 10W/2.1A power adapter with its newest iPad model – a step back down from the 12W/2.4A unit that has been included with the last two generations of full-sized iPad models.
While a 10W power adapter would theoretically require longer charging times, iFixit’s recent teardown confirmed that the iPad Air 2 contains a smaller battery than its predecessor, suggesting a possible justification for the lower-powered adapter.
It remains to be seen how much of a practical impact this will have, if any, in real-world use; the Air 2 may not charge any faster with the more powerful adapter.
