The Phix basic kit is a closed-loop system that uses replaceable pods.  The pods utilizes a ceramic wick to provide consistent flavor throughout the life of the 400 puff pod.  The version 2 has an upgraded battery from 280mAh to 320mAh giving you  approximately 320 puffs as well as the ability to do pass-through charging.  The battery indicator light now changes color to display the battery remaining (Blue - Full charge, Orange - Medium charge and Red - Low charge).   A juice window has been added, which also acts as an airflow control by blocking it with your finger.  Also included is a removable clip so that you hopefully don't lose it too often.  This unit has a very small form factor which makes it nice for when you need your fix while you're on the go.
