A Sub-Ohm Tank is a type of vaping device designed for use with low-resistance coils, typically below 1 ohm. This allows for greater vapor production and enhanced flavor, making it popular among vapers who enjoy a more intense experience. Sub-ohm tanks usually feature adjustable airflow and larger e-liquid capacities, providing a longer-lasting vaping session. These tanks are often paired with high-VG (vegetable glycerin) e-liquids, which produce thicker clouds. Users should be aware that sub-ohm vaping can consume more battery power and e-liquid, so it's essential to use compatible devices and follow safety guidelines to ensure a safe vaping experience.
