A general structure of Chern-Simons gauged supergravity in three dimensions within the embedding tensor formalism is reviewed. Although supersymmetry imposes some constraints on the embedding tensor that completely determine the full gauged theory, there are various possible consistent gauge groups due to the unrestricted number of vector fields to be introduced. Special emphasis is on the non-semisimple gauge groups and their equivalence to "conventional" Yang-Mills gauged supergravities obtained from dimensional reduction. The whole construction is then applied to the magical N=4 gauged supergravities with F4(4)/USp(6)xSU(2) and E6(2)/SU(6)xSU(2) scalar manifolds and SO(4)xT6 gauge group. The SO(4) vacua are given along with scalar masses at the N=4 AdS3 vacuum. Finally, possible higher dimensional origin for these two theories from dimensional reduction of magical N=(1,0) supergravities on S3 is pointed out.
