Made with new innovative 3D mesh coil technology are the Innokin Plex 3D Mesh Replacement Coils. These coils utilize advanced Plex3D heating material manufactured with specialized “micro-grooves” for increased surface area. These grooves, along side the mesh design, allow faster wicking by activating a capillary effect that allows e-liquid to move across the coil more rapidly while eliminating the potential for dry hits. These coil heads have a lower thermal mass that creates a faster heat up and cooling time to give them a longer overall lifespan. The 0.35 ohm Plex 3D Coil Head is rated for use at 30-55W to provide you with more cloud production and flavor enhancement at relatively lower wattages.
