Keyone USB charging cable.

Ordered an extra one from two suppliers and they did not have them, out of stock for a long time.

Amazon has some type C knock offs but reviews say cable does not sync properly, ??????.

Anyone have an idea on where to get an extra cable that will work without issues?

Thanks

Just order a type c cable from Amazon.
If you want to avoid the really cheap ones that may cause issues, I recommend either Aukey or Anker. Their products are usually good.

You probably have many micro USB cables. Just buy an adapter or two.
