I'm looking at either a zmax or vamo, but I was leaning toward the zmax due to the look. I know the big difference everyone notes on the V5 is that it can charge a cell phone which I don't really need. But it also appears to me that the V5 now has a redone fire button display, but I can't find any confirm/deny on this. It looks like the V5 shows Battery power, puff count, and a Res/Time/Volt. The V3 looks like it only showed 1 piece of info on fire. Can someone clear this up for me?
