You can make all the current in the world available to a capacitor 
and it is NOT going to charge any faster! To make a capacitor charge
faster you have to increase the applied voltage! Try and remember the
old analogies to clearify; current is the quantity of electrons and
voltage is the pressure the electrons are under. How any electrons 
you have available wont effect how fast a capacitor charges, but the 
amount of pressure (voltage) they are under will! If you keep the 
applied voltage the same but double the available current, you will
have to double the capacitance to use that available current.
