Frequently Asked Questions

Theoreon products are designed to work together, in order to give the user the best possible vaping experience.
While our cartomizers are compatible with Green Smoke batteries, we do recommend using our products together for the best experience.

Components and accessories from companies other than Green Smoke are not compatible, and attempting to use Theoreon's components and accessories with those of other companies invalidates the warranty.
