smok alien tank compatible with i just 2 battery using tfv8 coil 0.4
It should be. They both use a standard 510 connector so they will connect physically. The i just 2 is really just a fixed-wattage (
not variable wattage)
mechanical mod with some protection circuitry, so you could put a tank using a 0.4 ohm coil on top. The stock coil that comes with the i just 2 is 0.3 ohm.
The performance of the i just 2 will be very similar to a mechanical mod. The performance (vapor) will be dependent on the current battery voltage at the time of use: strongest when the battery is fully charged, and gradually and progressively weaken as the battery is discharged during use. Wattage output will probably be around 80 watts when fully charged, and 50 - 60 watts when close to being discharged.
