I was witness to the DNA Vaporshark at the local meet this past Sunday. Quality construction, DNA20 controlled and uber-stealth. I likey.
The dna 20 and the dna 30 are only the chip that runs the device, the 20-30 have no size specifics to them, just whatever the mod they are installed in.Can I add... what is the smallest user replaceable battery DNA20 or DNA30 mod?
As has already been said, the provari mini is the shortest regulated tube mod but they aren't cheap. One I haven't seen mentioned is the itaste SVD. Not the shortest available but like the telescoping zmax, you can use 18350, 18490, and 18650 batteries. I have one and I like it. You can find them reasonably priced as well. They aren't DNA powered but they are variable wattage.
