The YoCan Yocan Armor Vaporizer Kit features a built-in 380mAh rechargeable battery, YoCan's Quartz Dual Coil, and fires in a 3 tiered voltage output to generate discreet but flavorful clouds of vapor from concentrates. Operating with a single button, the Armor has a built-in 10 second preheat function to melt your materials and get them ready, just 2 clicks to start the preheat mode, and 2 clicks to end it early. The built-in Micro USB charging will fully charge the Armor's battery in just 30 minutes. All this power is routed through Yocan's famous Dual Quartz Rod coil to give you a perfect combination of flavor and vapor density.
