We propose to observe 4 X-ray bright gravitationally lensed mini-BAL quasars. The main scientific goals are to: (a) Investigate whether relativistic outflows are a common property of high-z mini-BAL quasars (b) infer the range of outflow properties of quasars at a redshift range where AGN feedback is thought to have had its major impact of galaxy evolution. Specifically we propose to add to the current sample 4 lensed quasars with properties that will significantly increase the parameter space of our study in UV outflow velocity and (c) test for the possible co-presence of moderate velocity outflows of a few 1000 km/s detected in the UV at distances of virgul100 parsec and ultrafast outflows launched at 10-100 rg scales in high redshift quasars.
