The phenomenon that causes your e-cig to shoot liquid into your mouth, commonly referred to as "spitback" can be caused by many different factors. What happens is that your coil has absorbed too much liquid and can't vaporise it as intended.
- Turn your e-cigarette upside down and hold down the fire button for 2-3 seconds. The residual liquid will then pour out of the mouthpiece. To speed up the process you can plug the mouthpiece up with paper towels and shake the liquid out.
- Restrict the airflow a tad, to increase the resistance of the air passing through the tank. This helps the juice reach the coil properly and vaporise. If your airflow is wide open there's a chance that too much liquid reaches the coil and floods it.
- Increase your wattage. If too low wattage is used the coil won't have a chance to vaporise residual liquid. Causing the coil to flood.
- If using a low VG liquid (<60%), try a higher VG liquid.
Depending on which coil is installed in your tank, it functions in different ways. Perhaps your coil doesn't suit your vaping style? A low resistance coil requires your mod to work harder, and can cause flooding if used incorrectly.
Rule of thumb regarding coil resistance (ohms):
- Lower resistance: Demands more power from your battery, the coil gets hotter which brings more vapor production.
- Higher resistance: Demands less power from your battery, which in turn makes for less vapor production.
