The G Pen Vaporizer has an auto-off feature to prevent it from overheating. After your button is held down for an extended period of time, it will shut itself off. We recommend allowing at least 20 seconds to pass between each use to maximize the life of your G Pen.
If you have any further questions please contact our Customer Service Department, which is available Monday through Friday, 8:00am to 5:00pm PST.
