How to get a greater(faster) current flow?

I am working on a circuit that has a voltage source of 5 volts. I am trying to charge a 1F capacitor at a quick rate(preferably under 30 seconds). The problem is that the voltage source has an internal resistance of 120Ω which is slowing down my charge rate. Is there anyway that I can amplify or boost the current flow despite that internal resistance?
Current mirror? Darlington Amplifier? I was thinking of trying these.

By the way, 5 volts is a DC voltage source.

Change your voltage source. And please don't double post.

How often do you need to charge it?
