A Sub-Ohm tank is a type of vape tank that uses low-resistance coils (below 1.0 ohm) to produce larger vapor clouds and more intense flavors. These tanks are designed for direct-to-lung (DTL) vaping, where you inhale vapor directly into your lungs, similar to taking a deep breath. Sub-ohm tanks are best paired with high-powered vape devices and are ideal for vapers who enjoy big clouds and bold flavors.

Sub-Ohm tanks work best with e-liquids that have a high VG (vegetable glycerin) content, usually 70% VG or higher. High VG e-liquids produce thicker clouds and smoother hits, making them perfect for sub-ohm vaping. Avoid using high-nicotine or high-PG e-liquids, as they can cause a harsh throat hit when used with low-resistance coils.

To minimize the risk of leaking, ensure all tank components are securely tightened, especially the coil and glass section. Avoid overfilling your tank, and always close the airflow vents when filling it with e-liquid. Using a thicker, high-VG e-liquid can also help reduce leakage. Additionally, store your vape device upright to prevent e-liquid from seeping out through the airflow holes.
