We're selling the 2200mAh eGo ONE as a complete kit! The 2200mAh version comes with a larger battery as well as a larger capacity tank (2.4ml as opposed to the 1.8ml tank that comes with the 1100mAh version). You'll also get a 15ml bottle of e-liquid, charger, a 1.0 ohm coil, a 0.5 ohm coil, charger, and wall adapter. The drip tip/mouthpiece is removable and 2 are also included with the kit. One is stainless steel and the other is what Joyetech is calling "organic glass" ¯\__/¯. The glass one has a slightly wider bore than the SS one to really get the most out of the more open settings of the tank's adjustable airflow. It's an outstanding all-in-one cloud chucker that rivals (if not surpasses, at least on the flavor front) the Sub Tank and the Atlantis!
