Not at all. I have a l'il problem with that myself. I also chain vape. Like til my MT3S BCC glows heavily in the infrared, and it actually heats up my Vision Spinner, so then I switch over to my Phoenix RBA Drip Rig with my Innokin Itaste SVD VV/VW telescoping mod, to let the other cool, so I can grab another vape of that friggin yummy Mochaccino I get from Laurin and Jeff at Wordupecig.com.... Yes, I totally get it. I bought all of the above stuff because I did exactly that! And the fifteen or so other tanks, atty's carts, rba's that have shown up in my mailbox in the year since I started vaping full time. It's not so bad now, because I was kind of experimenting, seeing the differences between carts and wicking tanks and short wick bcc's and rba's, and how each performed over a range of batteries and voltages and wattages. I quickly discovered that I really have to use a VV device, preferably one with variable wattage and an ohm meter as well, to get a really satisfying experience. Small single voltage batteries are ok if they are outputting at above 3.7v. I have a few that were custom made in a batch of 500, that output at 3.9v, and I actually prefer those over my original ego batteries, which output around 3.2v. Egads, I oughtta start a Vaper Anonymous group, Hello, my name is J.J., and I am a vapoholic.... (Hi, J.J.
