hey guys. I'm new here. This is my first post and I'm kinda new to Vaping as well. I currently have an Istick TC 100w with a Cleito tank. I run it at 40w. I really like that set up. I also have a nautilus X which I run around 16-17w. I can run either tank for 2-21/2 days before changing the batteries out. The problem is it's a little heavy to keep in my pocket while at work. I'm a painter/carpenter by trade. I work 10 hour days and about a 40-45 minute drive to and from. So I've been searching for a smaller mod that I can carry in my pocket that's a touch lighter and smaller than what I have now. I've been reading up on a few like the mini volt, target and even maybe the cool fire iv 18650, but I was wondering what you guys would suggest that could last me until I at least am able to get on my way home due to the fact I'm not always working some place I can just charge up. Any advice or suggestions would be greatly appreciated. Thanks in advance.
