Thanks supr and all others. I plugged an adapter cable, with a full size USB plug on one end, into the end of the power brick and the other end of the cable, with a micro usb plug, which I plugged into the bottom of the RC. All worked great.Oh also: the charge cable should be plugged into the power brick, not the port at the end of the "3 battery board". That Jack is for firmware updates which never happen.
How to fix/replace the port as I'm in the same situation. Tks!The port is a Micro-A USB port, which is compatible with the Micro-B plug that phones use, for example. Just be careful when you insert it, as it doesn't have the notches to prevent incorrect orientation.
No idea why DJI elected to use this port, and I think it is a terrible oversight. Many have forced the cable in backwards and broken the pins.
