Alright so check it out everypony. I'm in the market for a tough mechanical mod that I can use when I'm working outside. I'd like something telescopic so I'll have battery options. My charger can charge 18650, 18500, and 18490 batteries. I found an ohms law calculator online so I'll have an idea of my output anyway! But as I shop around on many of the vapor sites and EBay, I gotta say that I'm more confused than ever! Any suggestions?
