Sub-ohm tanks are by far the most popular accessories available for e-cigarettes. Innovative design has made today's vaping tanks more reliable and easier to use than ever. More importantly, though, modern sub-ohm tanks produce so much vapor that their owners never need to worry about building their own coils. With a sub-ohm tank such as the SMOK TFV12 Prince or the Freemax Fireluke Mesh, it is finally possible to use a tank to create a vapor cloud large enough to win a competition -- but don't take our word for it. While everyone else is wrapping wires around drill bits, you'll be swapping coils in seconds and getting back to vaping.
