Introducing The all new Ooze Tanker Extract Battery, A heavy-duty 510 thread vaporizer that goes to work to protect your most sensitive glass or ceramic oil cartridges. The Tanker is equipped with a thermal chamber that provides a barrier around the cartridge, and insulates the oil to improve the airflow. Standard batteries leave carts exposed and out in the open; the Tanker’s thermal chamber creates a protective forcefield around the glass or ceramic cartridge. The thermal chamber protects it from the occasional drop or fall, and ensures that it is safe when you put it away in a purse, pocket, or bag.
