I think you can run the 2 mp40's on the same outlet so long as the total amperage does not exceed that of the outlet you chose. Some of the outlets have a higher rating than the others and I'm not sure what amperage the mp40's pull. So with a little math it should be pretty easy to figure it out... I am running 2 koralias one 1 outlet as well as 2 sets of fans on another with no issues.
