SMOK V18 Mini Replacement Coils are designed for SMOK’s TFV18 Mini Sub-Ohm Tank. Each coil implements a mesh coil that spreads heat over a wider area. Three options are available: 0.15ohm Dual Meshed Coil, 0.2ohm Meshed Coil, and 0.33ohm Meshed Coil. The 0.15ohm Dual Meshed Coil is made to produce more vapor. The 0.2ohm Meshed Coil delivers good flavor but better vapor production. The 0.33ohm Meshed Coil is made for rich flavor and respectable vapor production. No matter which one you get you will be surprised by the performance these coils deliver.
