Requires x 18650 battery Vaporesso Gen Mod Vaporesso GEN Mod comes with an innovative casing which features 4 layers of coating, giving it soft rubber-like feel, yet still making it smooth to the touch. The final coating makes it scratch-proof and flame retardant. Powered by dual 18650 batteries (Not Included), the mod integrates with the advanced AXON chipset, featuring a wide output range of 5-220W and supporting pulse mode and power ECO mode. In the pulse mode, AXON will continuously give you a hit throughout your puff (every 0.02s) - not just from the initial fire - bringing you more powerful, flavorful clouds with every puff. When the power ECO mode is on, it can optimize your device\'s settings to give you that extra vaping time you need. At last, there is a 0.91\" OLED screen to show the essential vaping data clearly. 4 colors to choose from.
