The SMOK RPM Mesh coils have a larger surface area across the cotton for an even spread of heat. This allows the e liquid to heat up faster resulting in better cloud production and flavours. The SMOK RPM Triple Coils offers faster heating times and exceptional flavour production.The SMOK RPM Coils are designed to work with the following devices:– SMOK Scar P3 Kit (Mesh Only! With the RPM Pod)– SMOK Scar P5 Kit (Mesh Only!

These coils require a lot of power and heat up very quickly. To make sure your E Liquid doesn’t vaporise too fast leading to burned coils, we recommend using a thicker High VG E Liquid like our 70/30 E Liquids (70% VG to 30% PG).SMOK RPM Mesh 0.4Ω Coils– Recommenced 25WSMOK RPM Triple 0.6Ω Coils– Recommenced 25WIf you want to know more about E Liquid mixes and ratios, have a look at our E Liquid Guide.
