Unfortunately it is a problem to get ProRes material from the Mavic 3 Cine on my PC Win 10.
I do have a USB 3.1 Gen2 port, but probably with too little charging current (3A).
The download of the large MOV files (100GB and more) is very slow, which is why the flight battery drains and the transmission then naturally breaks down.

Is there a reasonable way since video footage is ProRes! transfer to pc?

thank you

Might be a dumb question, but are you using this cable?  DJI 10Gbps Lightspeed Data Cable

Yes i use the Lightspeedcable and the Flight Battery is loading slowly. The download time for 90 GB ist 45 Minutes, i mean that is a long time or not ?

i think i solved the Problem :-) i copy first time the MOV to an space off my NAS, that very slow 6-8 GB/s. now i copy the MOV to my SSD on my WIN10 PC, now is the Speed 700-800 GB/s -> that is fine :-)

Hmm, that is not my experience. I have 3.1 USB and I can offload to my SSD at 675MBps. Maybe check your drive/cable.

I'm using the same cable that I used just now to transfer 79GB in about 2 minutes (Macbook M1 Pro).  That very same cable took about 49 minutes yesterday to transfer approximately the same amount of data from the Mavic 3 Pro Cine.  

That's very very annoying.
