Some trial and error may be required to find the right settings for you, but the simple-to-use controls of the SERIES-B Tilt 50W box mod means that is easy to cycle through various power levels. Different e-liquids will perform very differently at a range of power levels. Some respond well at higher wattages, some will offer better flavour with less power. Airflow also has a big effect on the vapour produced. Sub-ohm vaping in particular requires plenty of airflow to prevent your wick from burning. Refer to the Voltage/Resistance/Wattage chart in your manual for more information.
