Description: The Vmod XL is one of the more popular well-funded projects in the bottom feeder world. One thing I like about the Vmod is that it is powered by 18650 batteries, meaning user will be able to replace the battery when it goes bad. Unlike mods with built-in battery packs. Another interesting feature – with the Vmod Xl is the usage of a new Two-chamber design”. One of the chambers feeds the e-juice into the atty. While the second chamber brings in fresh air through its nose cone.
