You can actually use any USB-C if you wanted. I personally do not use the USB/Charger cable that originally came with EMO as I live in AU and the plug is not supported here.
I have a power board that supports direct USB connection so I just simply plug the cable into there and to EMO’s skateboard and it works fine.
Regarding the other issues you are experiencing. Take a look at my guide I created, maybe some of the issues you are experiencing can help.
If you are still experiencing issues, it is recommended to take a video of the problems you have with EMO and send / submit them to the support team so they can offer further assistance and help to you. You can submit a support ticket here if you need it:
