Yes, your iPad certainly can provide power via USB-C to charge an external device. However, be aware that this will obviously impact the available battery endurance of your iPad.


I have not, to date, managed to find an absolute source power specification - and neither have I tested this capability. However, the iPad capabilities are known to be able to source 5V and standard PD power profiles over USB-C.


Quoting directly from Apple’s own documentation:


Away from a power outlet and need to charge your iPhone, other iPad, Apple Watch or third-party USB device? Just connect the right cable or adapter to iPad Pro to share its long-lasting battery with your other devices:

  • To charge your iPhone or earlier-model iPad that has a Lightning port, connect it to iPad Pro using the Apple USB-C to Lightning Cable. If you have a Lightning to USB cable, you can combine it with the Apple USB-C to USB Adapter, then connect the adapter to iPad Pro.
  • If you have two iPad Pro models with USB-C ports, you can connect them directly with a USB-C cable. One iPad Pro will draw power from the other. If you want to change which iPad Pro charges, unplug the USB-C cable and then reconnect them.
  • Charge your Apple Watch by connecting its Magnetic Charging Cable to iPad Pro via the Apple USB-C to USB Adapter. If you have an Apple Watch Magnetic Charger to USB-C Cable, you can connect it straight to iPad Pro.

I obviously cannot comment upon your own experience or setup - other than to refer you to Apple’s documentation.


An explicit feature of Apple’s USB-C implementation for iPad Pro, in addition to being able operate in Host/DFP and Peripheral/UFP modes, is the iPad’s ability to source power - specifically to charge other devices such as iPhone over USB.
