Few doubts about "Apple USB-C Charge Cable (2 m)"

Apple USB-C Charge Cable (2 m)

• Is it a Thunderbolt 3 cable?
• Which USB version this cable is using?
• Is it the same cable which comes with new MacBooks?

No, it's not a Thunderbolt cable. Although they have the same shape connectors, they are different things. You can tell by the icon on the plug whether a cable is TB or USB.

As for the version, that's more complex. Apple don't specify it on their page. This webpage https://9to5mac.com/2018/08/22/how-to-choose-a-usb-c-cable/ suggests that products called "charge cables" may have low data transfer speeds, and you may be better off getting a quality third-party USB-C cable that can handle USB3.1 SuperSpeed, if that's what you need.

Look for the correct "SuperSpeed" icon on the end of the plug.

It probably is the same cable that comes with a new Mac, but really you'll need to compare them.
