Bear in mind it will charge with pretty much any cable so don't feel obliged to pay apple tax on the "official" usb c charger!Didn't realise the new iPad Pros are USB C. Even worse, the cable is USB C to USB C so I need to buy a new cable! Hopefully the iPhone switches to USB C this year so that I don't need to carry two cables.
*Edit* just to qualify that my 11"pro charges fine on a nexus 6p charger, an HTC u11 charger and a Huawei mate 20pro charger but your milage may vary!
