Some groups advocate that there is a “second filling” or a “Holy Spirit baptism” that believers will get after they have been born again (at some unspecified later time). There is no Scriptural support for this claim.
While Cornelius experienced a special “baptism” by the Holy Spirit, it was done as a special sign to the early church to show that Gentiles were also now to receive the Holy Spirit. This was a one-time special case event to show the early apostles (who were nearly all Jews) that God’s grace now extended to the Gentiles. From the cited reference: 
In effect, the Holy Spirit baptism given to Cornelius was analogous to the pouring out of the Holy Spirit upon the Jewish apostles at Pentecost. So, the gospel thereby and thereafter spread out to go to the Gentiles also. Amen!
