The SMOK RPM Coil is a replacement coil designed for the SMOK RPM series of devices, including the RPM40, RPM80, RPM Lite, and others. Specifically, the “SMOK RPM Coil – Mesh 0.4” refers to a coil option that features a mesh heating element with a resistance of 0.4 ohms. Here’s a detailed description of the coil:

1. Coil Design and Build: The SMOK RPM Coil – Mesh 0.4 utilizes a mesh heating element. The mesh design provides increased surface area contact with the e-liquid, resulting in improved heating and vaporization. It offers a balance between flavor and vapor production, making it suitable for both direct lung (DL) and restricted direct lung (RDL) vaping styles.
2. Resistance and Power Range: The Mesh 0.4 coil has a resistance of 0.4 ohms, which is optimized for DL and RDL vaping. It is designed to operate within a specific power range recommended by the coil manufacturer and your device. Ensure compatibility with the recommended wattage range specified by the coil manufacturer and your device.
3. Coil Compatibility: The SMOK RPM Coil – Mesh 0.4 is compatible with a range of SMOK devices that utilize RPM coils. These devices generally include the RPM40, RPM80, RPM Lite, and various other models in the RPM series. Verify compatibility with your specific device before purchasing the coil.
4. E-liquid Compatibility: The Mesh 0.4 coil is suitable for use with various e-liquids, including both freebase nicotine and nicotine salt formulations. It is particularly well-suited for e-liquids with lower nicotine concentrations and higher VG (vegetable glycerin) ratios, as it can handle higher wattage outputs for enhanced vapor production.
5. Installation and Replacement: To install or replace the coil, typically remove the pod or tank from your SMOK device, unscrew the existing coil, and securely screw in the new Mesh 0.4 coil. Remember to prime the coil by adding a few drops of e-liquid directly onto the cotton wicking material before use to ensure proper saturation and prevent dry hits.
6. Lifespan and Maintenance: The lifespan of the SMOK RPM Coil – Mesh 0.4 can vary depending on factors such as usage, e-liquid composition, and vaping habits. It is recommended to monitor the flavor and vapor production regularly and replace the coil when you notice a decline in performance or a burnt taste. Proper care and regular cleaning of your device can help extend the lifespan of the coil.
7. Packaging and Availability: The SMOK RPM Coil – Mesh 0.4 is typically sold in packs containing multiple coils, commonly ranging from 3 to 5 coils per pack. The availability may vary depending on your location and the retailer you choose to purchase from.
