The Vaporesso GEN X 220W TC Box MOD combines the aircraft-grade aluminum construction with CNC machining in a compact unit. And the Vaporesso GEN X comes with intelligent Axon chip inside, which offers new PULSE mode. The Pulse Mode will continuously give vapers a hit throughout the puff (every 0.02s) – not just from the initial fire. The Power ECO Mode makes longer battery life. The Smart TC Mode can provide an one-step temperature control with the automatic identification of tanks. Moreover, you can vape with manual settings in DIY Mode. Powered by dual 18650 batteries (not included), the Vaporesso GEN X device can fire out max 220W output to bring you a powerful vaping. The Vaporesso GEN X MOD is perfectly compatible with NRG-S Tank and NRG GT Coil.
