   The G Pen Connect offers compatible glass-on-glass attachments in 10mm*, 14mm and 18mm*, making it a well-suited partner to any female-jointed water piece. A spring-loaded carb release button creates instant airflow, allowing the chamber to be effortlessly cleared.

   The G Pen Connect turns any water piece with a glass-to-glass connection into a powerful e-rig. This palm-sized innovation is engineered with patented reverse airflow technology and a spring-loaded carb release button. The ceramic heating element evenly heats solid concentrate to deliver pure, flavorful vapor. The Connect features a magnetic tank cap and 850mAh battery.

   All you need to do is to connect the Grenco Science G Pen Connect Vaporizer and you’re sure to drop whatever wax concentrate vaporizer you’re using right now. You’re sure to keep yourself connected and never look back to using other independent vaporizers. There’s so much advantage to using water pieces compared to the average atomizer build. First, you’re getting that additional filtration from the water and second, the vapors produced by the vaporizer are then moisturized. This means that the vapors you inhale are not only filtered for irritants and impurities but are also cooled down allowing for a more convenient and a more comfortable vaping experience.

   Load your favorite concentrate into the ceramic tank and secure the magnetic cap. Connect the tank to the top of the battery via magnetic plate, and insert the glass adapter into the open end. Insert the glass end into your water pipe; five clicks will power the G Pen Connect on, and three clicks will take you through the different voltages. Once you’ve decided on your temperature, two clicks will begin the heat-up process. The button will flash for five seconds indicating the heat-up phase, then the light will hold solid for 10 seconds to let you know when it’s reached the maximum heating output. From there, you can take a draw and enjoy your water-filtered concentrate.
