The Vaporesso GT Core GT Mesh replacement coils have been designed for use with the Vaporesso NRG Tank. These coils are used for sub ohm vaping. These coils feature 0.18 ohm resistance and can be used with a wattage range between 50W to 90W. The Mesh Coil technology allows for quicker and more even heating compared to standard coils, this in turn creates greater clouds and better flavour as well as better coil life.
