Hi, I am fairly new to vaping, I have vaped with my friends a couple times and decided I wanted to get my own box mod to chase clouds with. The only problem is, I have no idea what's what when it comes to mods. I have one picked out (snow wolf 200) but my friends tell me that I need to build coils, and pick an RDA, or tank, and have married batteries. I have no idea what any of that means and I was hoping to get some help from some pros that could explain it to me. Thank you in advance to anyone who helps!
