The draw is the same as the mini-me, I think .5 amp's or something like that. I run both the mme and mmp off of the same 6volt, 10amph battery.
Per the apogee site:
The Mini-MP is not critical about its power-supply at all; any DC voltage 6-14 Volt at 1 Amp will be sufficient.
Does that tell you what you wanted to know?
?
Hope this helps
