The Aspire K3 tank is a plus-ohm tank designed for mouth-to-lung vaping, which takes advantage of the ever so popular nautilus coils. Please note that although the K3 tank can take the Nautilus 0.4ohm & 0.7ohm coils, it is not recommended due to the tank not having adjustable airflow which would suit those resistances. It is recommended that you use either the Nautilus 1.6ohm & 1.8ohm coils. The K3 tank comes fitted with a 1.8ohm coil.

For those who own the Aspire K3 Quick Start Kit, this is the same tank that you would have had in the original kit.
