It works daisy chained, no problem. Actual current draw according to the manual is high though, 190 mA, so your main supply unit has to be relatively powerful if you have many pedals.
One thing I love about these recent EHX effects is that they seem to be insensitive to PSU, outlet, etc. Boss or Ibanez PSU work fine. Not like say the Line6 tonecore pedals, which were a pain.
