Fuel tank 12dc juicy lucy to power 9v dc pedals,safe?

[Louie Angulo <louie.angulo@googlemail.com>]

Hi gang,
would it be safe tu use something like the the fuel tank juicy lucy

http://t-rex-effects.com/Default.aspx?ID=94&ProductID=PROD8&VariantID
(which puts out  5X 12v dc of 300ma for each output)

for the following pedals:

adrenalinn (normally requires 9v dc 500ma)
tc harmony G (normally requires 12v dc 500ma)
tc VT create (normally requires 12v dc 500ma)
EH micro POG (requires 9,6V DC 200 mA)

so as you can see: 
the adrenalinn requires more ma than the usual 9v dc pedals,and it does not run on batteries would it be ok then to use the 12v for it?
the tc harmony G is 12v but requires 500ma (more than what the juicy can provide per output)but i can use a doubler cable to use 2 of the outputs of the juicy to use a total of 600ma
that leaves me with the tc VT create
and the EH Micro pog,this one does not take batteries either would it be safe to use the 12v dc?
ive been told some 9v dc pedals take 12v dc without any problems...
cheers
Luis
