I bought DJI Mavic Mini few days ago. I cannot charge RC with standard USB mini cable. Only USB cable attached to box is working. Is it normal? Connection beetween RC and my smartphone is working perfectly...

Are you sure that your “standard USB” cable is a “standard “ cable and not a data only cable?

I would try another cable and also be careful with the orientation of the micro plug going into the RC. The correct orientation is shown on the RC next to the micro connector. The micro connector used on the RC is more of a rectangle then a trapezoid like mist micro connectors so it is possible to plug it in the wrong way some folks are reporting.

I checked few usb mini cables. They cannot charge RC. They work perfectly with other equipement.
The cable from the box is charging box but not always. When I move cable a little it stops charging.

Hi. I am sorry for the trouble and thank you for reaching out to DJI Forum. With regards to the charging concern. May I know if when using the USB cable that is included on the box of the DJI Mavic Mini will be able to charge the remote controller properly? Just a friendly reminder that we do not recommend using third party cable accessories in charging the drone and remote controller. This thir party accessories or cable may be able to work but we cannot guarantee if they will world properly every time you use it. Thank you.

I can charge RC with original cable but when i move cable a little it stops charging. I must take out the cable and place it again to continue charging. I think there is some problem with RC usb port.

It's microUSB not mini, but you wouldn't be able to jam in the mini USB cable connector anyway.
Get good quality microUSB cable and it should work if the original cable works fine.
