There are several GOTCHA’S that can trip you up regarding cables.
Normally USB 3.0 means 5Mbits/sec and USB 3.1 means 10 Mbits/sec.
Normally “high speed” means 5Mbits/sec and “super speed” means 10Mbits/sec.
USB 3.1 (“original or “issue one”) as used on Apple products, is sometimes called USB 3.1, but is limited to 5 Mbits/sec, typically called “high speed”. So, some type c “high speed” “USB 3.1” cables sold to Apple users actually only communicate at 5Mbits/sec. Some of them are called the SAME, but communicate at 10Mbits/sec if connected to a non-Apple machine that supports true USB 3.1.
This is because of changing naming standards. USB 3.1 superspeed 10Mbits/sec is technically “USB 3.1-2”, but nobody uses that term.

I’d suggest if you have the superspeed port (hardly anybody has one at this writing) and want a superspeed cable, look for the “superspeed” designation or the 10Mbits/sec spec. Sometimes 10Mbits/sec cables are listed as “highspeed”, just to add to the confusion.

OF COURSE, USB 3.1 IS THE DESIRABLE CABLE TO USE WITH FUTURE DEVICES,

USB3.1 superspeed cables or ports can be either type A (square) or type c (oval, reversible).

Also, not all type c cables support 3A currents. They should have a statement that they support charging at high currents. Being just a “data sync” cable doesn’t say anything about whether they work with various chargers.

Most of these things will iron themselves out in a year or so, but for now, read the description carefully.
