USB Type C Power output confirmation

Hi,

I want to know about USB Type C port specification in Laptops.

I searched this laptop Lenovo  thinkpad x series and its mentioned as USB Type C port support. But, am not sure how much power we can get from this port?.

As per USB standard specificaiton, we can get 3 different current levels from USB Type C port. Is this applicable for all recent USB Type C supported laptops?

Could you pls confirm this??.
