One of the harsh lessons from the iPad Pro is that big batteries take a long time to charge -- forget to plug it in at night and you could be in for a hassle in the morning. Apple is finally tackling that problem today, though. Alongside the 9.7-inch Pro, it's
introducing a 29W USB-C power adapter for the 12.9-inch iPad Pro that should charge your tablet much more quickly than the 12W adapter that comes in the box. You'll need a computer with a USB-C port for this to work, of course, but it could be worth the $49 to save yourself some time during every recharge.
Update: As it turns out, the adapter itself is actually the same one that comes with the latest MacBook. But the Lightning to USB-C cable is certainly a new offer from Apple.
