Sub-ohm tanks are a popular type of tank designed for sub-ohm vaping. They feature low-resistance coils that operate at less than 1 ohm, allowing for higher wattage and increased vapor production. Sub-ohm tanks often have adjustable airflow and larger e-liquid capacity, making them suitable for direct-to-lung inhales and cloud chasing. These tanks are favored by vapers who enjoy a warm and flavorful vape with dense clouds. Sub-ohm tanks offer a convenient and user-friendly option for vapers looking to enhance their vaping experience.
