The Carbon Copy is only 26mA. If you want something that can supply 500ma to a single pedal, only a separate, dedicated supply for the Grail will work (Not even the Cioks supplies go that high, topping out at 400mA). A Voodoo Labs PP2+ will handle just about anything else you throw at it (and
is switchable voltage ...for each output too). Otherwise, upgrade your Grail to the version 2, which draws only 200mA.
