My wife is using a regular Ivape 5v passthru with a 5v madvapes wall adaptor, and a Cisco 1.5 LR atomizer. She is getting tons of vapor and loving it. I don't have a volt meter but if this is correct shouldn't this be blowing the atomizer? I was going to get her a wet box and I am torn between the 3.7 or the 5v, since she is taking this atomizer to the limit for about 2-3 weeks.
