SV Mini Phantom e-cigarette tank is like a refillable cartridge. Intended for use with the XL batteries. Can be filled with 1 mL of any standard SV e-liquids. Uses a 1.6 ohm USA Kanthol wire for a high quality vapor experience. Tronic and InneVape e-liquids are not recommended (may be too thick depending on the flavour). We do not recommend high VG liquids (like Tronic “Max VG” Fairy Juice with 93% VG) because those are very thick and will not absorb well in the wick in this small tank. Standard 510 threads to fit batteries with 510 threads. We recommend purchasing 2 tanks at a time, since the tank lasts for about 10 – 20 fills (equivalent to about 10 – 20 packs of cigarettes). It’s time to replace the tank when the wick is burned out. You may notice some e-liquid leaking into the inhaled vapours, or you may notice a burned taste that does not go away.
