There are two types of Freemax ST Mesh Coils available: the 0.5 ohm and the 0.35 ohm. The 0.5 ohm choice is great for 18 watts, while the second one is suitable for 25-30 watts, which is better for 28 watts, which is better for DTL vaping. Additionally, the coil's ability to absorb oil is accelerated by the tea fiber cotton used, allowing you to start vaping right away.
