Morning Nelson,
Joshua here, to clarify so that we are both on the same page. Are you looking for a USB-C to USB-3 adapter or a USB-C to USB3 cable in particular?
What device do you intend to power, I ask because not all USB-C cables are created the same, the wrong USB-C cable could easily destroy your laptop or phone (Pray before you buy USB-C cables http://buff.ly/1X7g13p).
Long story short, I can get you the cable you are asking for by next week Thursday, would just like to know a few details.
Kind Regards,
Joshua Kinuthia
