The All-in-One is ready to be drawn upon as soon as you take it out of the box. The battery is built into the device and should last as long the oil inside. As you draw air into the pen, a sensor in the tip signals the battery to heat the oil, turning it into vapor. The tip of the pen is a W that will light up as you draw upon the pen.

Is it possible to refill the cartridges? My concerns is recycling. I do enjoy the disposal when traveling or special events. However, for long term using your product daily. On average use 3-4 cartridges a month. I only use cannabis for chronic pain. I use micro dosing throughout the day works for me.
