5 pack - SMOK Spirals Tank Replacement Atomisers. Dual core, high capacity. For SMOK Spirals tank.
Due to the low resistance, these SMOK Spirals Atomisers are only compatible with high-powered high-amp high-drain batteries, and you do need a powerful battery with these Smok Spirals atomisers - low wattage/ampage batteries are not powerful enough and would over-heat. DO NOT continue if your battery is getting too hot. Also, use zero or low nicotine e-liquids if you're into making vast amounts of vapour clouds. Medium or high nicotine liquids will burn harshly and not taste nice or may make you feel ill. For the biggest clouds you need a thicker e-liquid with a very high % of Vegetable Glycerine. Also start with the smallest airflow control hole and work up. Make sure the cotton wick is fully soaked before vaping.
