The Ce4 Disposable Tank is one of the oldest designs for clearomizers that there is, and it is still one of the most used and trusted tanks available. They are a top coil and top filling tank which means that you don’t have to remove the tank from the battery to fill it which a lot of people love. To fill a Ce4 the user simply unscrews the mouthpiece from the top taking care not to loose the little o-ring. Pour the liquid down the side of the wall taking care not to allow any liquid to enter the little metal hole in the centre of the tank as you look into it as this is the airflow tube where the vapour comes from. If any liquid gets in this tube it will cause a gargling noise and it will result in poor vapour performance.
Note: It is recommended that you change your clearomizer every 4-6 weeks. The life span of your clearomizer may differ depending on ypur specific usage and this is just a guage.
