Usb 3 port is a real one but is of micro usb 3 type with and included adaptator to USB 3.0
Much more intersting is the Usb Type C port (also named USB 3.1) who can charge the tablet, deliver HDMI video out, and connect to a USB3 hard drive by using a hub like the “dodocool 7 in 1” or any brand equivalent.
It looks like it. It says SuperSpeed USB 3.0 on the cable. Just got my tablet so couldn’t test it yet but looking at the thickness of the cable I believe it could be true.
But also, the USB 3.1 Type-C is way more interesting. 🙂
