This is a 1.0 F capacitor [0], we use similar ones for short-term UPS backup so our embedded systems can shut down safely. And a Coulomb is one amp for one second, that's not exactly large either. So it's not that coulombs and amps are too large a unit, it's that it's hard to convert and store large amounts of energy.
