What does it mean when your vape crackles?
Most often this will be caused by your device needing a replacement coil - faulty or damaged coils will cause this. Alternatively, your device’s wattage could be too low. If it is too low to properly heat the coil, it can cause flooding and gurgling. Finally, watch that you haven’t added excess liquid to your tank, or even over-saturated your coil when priming.
