Hey guys, this is my first real question, so let me say thanks for the help in advance and consider this my introduction. I'm a relatively new ecig user, and my first mod was a ProVari V1. I've been recently looking at low impedance cartos that require 4 amps of current. This, as I've come to find, is one of the main limitations of the V1. My question is, are there any mods out there that will handle that level of current and yet give the versatility of the ProVari?
