The Cobble AIO (All In One) kit is designed to be more compact and easy to use for the everyday busy body. The Cobble is a 700mAh rechargeable battery that lasts long for a device this small. It uses an auto draw system, where the sensor detects when the user inhales, thus releases the vapor. What the kit comes with is a 1.8ml disposable pod with a 1.4ohm BVC coil. The pod uses a more restrictive airflow making the vapor and flavor production a more mouth to lung inhale.
