To fly more in Canada. I need a sound solution in winter.
So this is the plan:

A 20000mAh power bank connect to Remote Controller side Micro-USB port for charging the controller.
Remote Controller bottom big USB-A to iPhone using a normal lightening cable.
Turn on the setting for charging the phone from RC.

Has anyone done this before?
I know in warm area, this is never a problem.
But for me, I need a very "cool" plan. LOL

Thanks and really appreciate it if DJI tech can confirm this will work.

Being in Montréal myself, I don't think the issues comes from the RC but rather from the moving part of the drone and from the battery short life under the cold.  That is why I don't fly under 0C.

My phone starts dropping battery life dramatically when is it under 5C. Getting the battery replace today.
But still like to have a solution to have the power bank working with the system.
