Thank you for the answer. I use drone for military monitoring missions and can fly all day, that’s why I want to connect power bank and have non stopped charging for remote controller and my device.
Yes, I want to charge my iPhone from the remote controller. For example, Android devices charge from the remote controller, I checked it today. It's very good when you want fly for long time and have powerbank for remote controller.
I have a problem with my evo lite +, when I connect lighting cable from my iPhone, my phone start charging, then Remote controller make beep and phone charging is off. All other services work perfectly, but my phone is not charging. How I can solve this problem?
