I did once have a USB battery bank that could output 12v, that I did try to use to run a laptop that could run on 12v. Unfortunately it needed twice the amps the pack could provide, much to my disappointment in realizing that the stated max discharge per port was actually for both ports as well (so one port could provide the full power, or both ports half power) negating my "hack" of using both ports.
