Which version of USB-C port does my laptop have?

Solution 1:

It's some version of USB 3. Hard to say which one based on the specs.

Avoid the USB-C 2.0 version, it would be slooow. Any of the other two will work. If your ports are gen 2, the gen 1 replicator will only replicate gen 1. If your ports are gen 1, then gen 2 replicator will still replicate only gen 1.
