Mavic/Spark Remote Controller Tablet Holderhttps://store.dji.com/product/mavic-2-remote-controller-tablet-holder
What cable do you use to connect the controller to an iPad mini? The supplied cable is way too short.

Hi, thank you for reaching out. You can use the bottom USB port using your own apple cable or any communication cable. Please make sure that you disconnect the side port once you use the bottom USB port since there is a possibility that any of those port will not work if it is plug at the same time. Please let us know if you have other inquiries or concerns. Thank you for your continued support!
