My understanding of the squeeze, and someone please correct me if I'm wrong as mine isn't here yet, is that it puts out 3.7v to a max of 50w so it's all about how you build. Before I ordered one I just built on a regulated putting out 3.7v till I found a sweet spot for the watts. If I remember rightly a .5 coil was about 28 ish watts, so to get up above 30w I just had to build down to .4.
I currently use a wasp on my mech with a .3 ish stainless coil using vtc5a's and 2 batteries will last me day and night.
