The SMOK Spirals Plus Tank is a larger 4ml tank atomizer that follows the smaller, sub-ohm atomizer in the series. Just like its predecessor, it has been built for top flavor outputs and utilizes the enlarged Spirals Coil Structure for maximum flavor generation. Its larger 24.5mm diameter doubles tank capacity to 4ml. It also features generous, bottom airflow slots that provide adequate cooling to the complex coil heads inside while maintaining a flavor focused draw throughout. The included Spirals Coils fire at a resistance of 0.6ohms or 0.3ohms, which are ideally suited to providing an exceptionally flavorful vapor that many tank atomizers will struggle to beat.
