This category was created for Advanced Tanks of e-cigs. These atomizers are more complex, so you will need more skills and knowledge to operate them. The majority of advanced tanks have adjustable airflow setting, some are RBA Rebuildable atomizers, which can accommodate DIY coils. There are also some devices with adjustable vapour temperature control and many other features. These atomizers require powerful battery devices where you can adjust Voltage and Wattage settings. Also you may need e-liquid with higher VG ratio like 50/50 or you can choose our 90% VG e-liquid, which was specifically designed for use in such tanks.
