Your practical guide to nicotine boosters
Understand strengths, open your bottle and prepare your mixture, step by step.
Boosters are delivered separately from your e-liquid. The mixture is not prepared before dispatch: you must mix it yourself.
Quantities for a 50 ml e-liquid
The instructions below apply to 50 ml of nicotine-free e-liquid and 10 ml boosters at 20 mg/ml, containing nicotine or nicotine salts.
| Preparation | Final volume | Final strength |
|---|---|---|
| Without booster | 50 ml | 0 mg/ml |
| With 1 booster | 60 ml | ~3 mg/ml |
| With 2 boosters | 70 ml | ~6 mg/ml |
| With 3 boosters in total | 80 ml | ~8 mg/ml |
| With 4 boosters in total | 90 ml | ~9 mg/ml |
The ~ symbol indicates a rounded strength. These quantities do not apply to other e-liquid volumes or boosters with a different concentration.
The strengths ~8 mg/ml and ~9 mg/ml correspond to 7.5 mg/ml and 8.9 mg/ml respectively before rounding. Volumes of 80 ml and 90 ml exceed the capacity of 70 ml or 75 ml bottles: use a container suitable for the final volume, with room to shake the mixture.
How to prepare the mixture
- Check your e-liquid volume, the booster strength and the space available in the bottle.
- Unscrew the cap and remove the dispensing tip.
- Pour in the boosters required for your preparation.
- Replace the tip and cap, then shake the bottle thoroughly to mix evenly.
What is the bottle opener for?
Some dispensing tips are difficult to remove by hand. An opener designed for e-liquid bottles helps lift the tip to access the opening and add boosters. It is not used to unscrew the cap.
Use it according to its instructions and check compatibility with your bottle. Avoid forcing the tip with a sharp object.
Understanding flavoured boosters
An unflavoured booster adds volume without adding flavour: the original liquid’s flavour concentration decreases. A flavoured booster adds its own flavours. It may change the taste of the mixture; it does not guarantee that the original intensity or flavour profile is maintained.
Precautions
Follow the precautions on the bottles. Avoid contact with skin and eyes. Keep e-liquids and boosters out of reach of children and animals. Nicotine is addictive.
