I wouldn't use that port for flying to be honest.....it is already a "janky" easy to damage port and I just would not trust that I have always used the bottom port on the mavic remotes. I used to use that side port, until figuring out that cables tend to get loose and it just wasn't reliable (transmission cutouts/disconnected) the bottom port for me is just always the way to go and has done great.....anyway I would honestly just get a magnetic cable and keep that little magnet piece inside the remote. ....(the port where you charge, smaller port) and I would just strictly use that for charging. It's crazy to how DJI designed the charge port because technically it's not even an Android type usb 2.0 tybe b it's actually USB type A.... and why they use that I have no clue technically you can use the Android USB 2.0 type B, which is your standard Android charger you just have to be careful not to insert it backwards or forcefully insert it the correct way yes you heard that right.... you have to be very careful inserting it the correct way because of the shape. A lot of people who are new to flying drones probably have never even seen a USB type A and try to insert them backwards or forcefully and just trying to insert the plug in, in general. and this is how you get a messed up port. I myself have never had any problems with the port because I did a little research on why I had a square port and why it didn't look like an Android port LOL and this is what I found out.... so just relaying some of the information I found
