The Vaporesso GEN Kit with SKRR-S Tank features the dual 18650 (not included) GEN mod with output wattage up to 220w. The mod is paired with the 8ml SKRR-S Tank that uses Vaporesso's QF coils. The device is powered by the new AXON Chip that makes it easier than ever to operate and customize your vaping experience. The exterior of the GEN mod is made from 4 layers of coating, giving it a soft rubber-like feel that is smooth to the touch. It also features "Pulse Mode" that will continuously give you a hit throughout your puff (every 0.02 seconds), resulting in more powerful, flavorful clouds.
