OK, so more of an integrator. Generally speaking, if it is too small it won't be able to hold a voltage against load, if it is too big it could have too much in rush current or not filter properly (electrolytic caps are far from an ideal capacitor). Regardless, there is no free lunch. Capacitors can only store power. They can't produce power.
