The GeekVape Illusion Mini Sub-Ohm Tank offers the widest range of cross compatibility in next generation atomizers, with native support for both SMOK TFV8 Baby Beast and Aspire Atlantis coil structures, making it unparalleled in the choices and options for output. The Illusion Mini measures 25mm in diameter and is filled with a traditional threaded top fill system. The Illusion Mini offers the most robust coil compatibility of next generation Sub-Ohm Tanks, with native support for the highly regarded SMOK TFV8 Baby Beast and the classic Aspire Atlantis coil families. The iM4 Coil included with each set is built to compete with the TFV8 Baby Beast coil structures, measuring 0.15 ohms in a quad vertical coil arrangement and an output range of 50 to 120W. The iM1 coil features a threaded adapter installed to the base of the coil and is designed as direct competition to the Aspire Atlantis coil structures, measuring 0.5 ohms with a recommended range of 40 to 70W. The Illusion Mini features dual 12mm by 2mm airslotes located around the base which can be adjusted based on preference. Quite possibly the most robust atomizer released this season, offering a next generation chassis with support for the most popular coil structures of this and last generation, GeekVape's Illusion Mini Sub-Ohm Tank positions itself as a true jack of all trades and a must buy for this generation.
