Vortex Nutrabolt Portable Mixer v 2.0.0, 18 fl oz

Would this work with Li-Ion 3.6v batteries? I imagine the higher voltage would make the blender twice as fast/powerful, which could be great.

can it blend ice, as in if i put in ice with my shake powder and ice mixture?

does anybody use this for just the vortexing of water and notice any difference in taste from non vortexed water?

How do you clean the "inner lid"? most people that gave bad reviews are about not being able to clean part of the lid or inner seal...
