Apple's 18W USB-C power adapter should charge new iPad Pro models faster, and it will also be able to be used for fast charging for Apple's newest iPhones when paired with a USB-C to Lightning cable.
Apple is including a 1m USB-C charge cable along with the 18W USB-C power adapter that comes with the iPad Pro, and while the cable is available for purchase separately, the 18W power adapter can't be bought as a standalone product just yet.
Rumors suggested that supply of the power adapter could be low at first, which may explain why it's not available for purchase separately from the iPad Pro. Apple is likely to offer the 18W adapter for sale in the near future, though.
The new iPad Pro models are available for purchase from Apple's website starting today, with new orders set to arrive on November 7.
