I've been emailing some manufacturers of gear to get some help confirming current draw numbers in the Archive section. Here's the response from SD wrt the MP2, running 48v phantom power with a pair of mics drawing 4 mA:
48 V x 0.04 A x 2 (mics) = 3.84 W drawn from phantom mics
6 V x 0.096 A = 0.58 W drawing at idle
add another couple hundred mW for operation = 4.62 W
4.62 W / 6 V = 0.77 A (770 mA @ 6 V)
770 mA is your magic number. Again, you can see that phantom is the
major source of current draw.
Running the numbers again using 15 V phantom, even if the microphones draw twice the current will give you...530 mA. So, if you can use the lower phantom position, you lower current draw by more than 30%.
