The EVIO C Pod is designed to be used exclusively with the Joyetech EVIO C. The pod itself can be used for both MTL and DL vaping by simply pulling it out the from the device and inserting the other way around. This switches the airflow between a restricted airflow and a more open airflow. It also features an easy side filling port as well as a push fit connection meaning no mess when filling and replacing the coil.
