A Sub-Ohm Tank is a type of vaping device designed for use with low-resistance coils, typically below one ohm. These tanks allow for greater vapor production and enhanced flavor, making them popular among experienced vapers. They work by using a larger coil and more airflow, which helps to create thicker clouds of vapor. Sub-Ohm Tanks are often filled with e-liquid and feature adjustable airflow settings to customize the vaping experience. They are compatible with various e-liquids, particularly those with higher VG (vegetable glycerin) content, which contributes to the smoothness and density of the vapor produced.
