I have been trying desperately to find a mod that will run Valerian coils/tank and will last all day. I would also like to find a tank that could hold a very very large amount of e-liquid. As you can see from the title I go through 50 sometimes 70 mL of e-juice per day. I would love to find a model that runs directly from a wall outlet rather than batteries. I work around 14 hours per day six days a week as a truck driver and changing batteries and filling tanks multiple times throughout the day is not the safest. If you have any suggestions I would greatly appreciate them. I just don’t want to smoke another analog cigarette again, and hope someday I will be able to give up the new habit of vaping also.
