While I've worked with a couple of USB 3.1 (Gen 2) external enclosures each of which was equipped with a USB Type-A port, neither was equipped with a Thunderbolt port (although the PC contained a USB Type-C port as well as a Type-A port).
I have heard, however, that there's a fair amount of incompatibility problems arising with these Thunderbolt-Type C connectors although I've had no direct experience with them. You might take a look at http://blog.fosketts.net/2016/10/29/total-nightmare-usb-c-thunderbolt-3/ for a recent article on the subject.
Also, in case you haven't done so, do a Google search on the specific type of device in which you're interested.
