Table Key

Vapour Production

  • Regular - A satisfying amount for most vapers
  • High - A larger cloud of vapour, generally used with lower nicotine strength
  • Ultra - Huge clouds of vapour, almost always used with very low nicotine strength


  • Regular - Reminiscent of a combustible cigarette
  • Airy - A more open draw, particularly with airflow fully open
  • Open - Very free airflow, suitable for cloud production

Suggested Power

  • This is our suggested power settings for the atomizer head to produce a balance of vapour, throat hit and flavour.

Suggested E-liquid

  • These are our preferred nicotine strengths for these atomizer heads. You can use different strengths as you prefer, as the atomizer heads will function perfectly with all strengths
