You can use Apple 12W and 10W USB power adapters to charge your iPad, iPhone, iPod, Apple Watch, and other Apple accessories, like AirPods and Siri Remote. Just connect your device to the power adapter with the Lightning to USB Cable, 30-pin to USB cable, or Apple Watch charger that came with your device.
Using an Apple 12W or 10W USB power adapter can charge some Apple devices and accessories faster than a 5W power adapter. When using an Apple 29W USB-C Power Adapter and Apple USB-C to Lightning cable, you can fast charge your iPad Pro 12.9-inch.
If you're not sure which power adapter came with your iPad, look on the bottom of the power adapter or identify your iPad model.
