G Pen Vaporizer description

G Pen Vaporizer

The G Pen from Grenco Science is a convenient, effective, and sleek vaporizer for solid concentrates. Easy loading and simple operation makes the G Pen one of the most user-friendly portable vaporizers available. G Pen technology allows for instant, vapor at the push of a button.

Portable and Lightweight

At just over 5" in length, the G Pen is sleek, stealthy, and fits in your pocket for on the go use. Even when you are out and about, you’ll always have access to high-quality vapor.

Easy to Use

Less parts means less hassle. Load your solid concentrate into the G Tank and reassemble cartridge, battery, and mouthpiece to begin use. Press power button firmly while drawing.


For best functionality, be sure to clean and maintain the G Pen regularly. Cleaning the screw threads with a clear alcohol solution ensures consistent electric conduction to the device. Allow G Pen to dry thoroughly before use. When the battery is depleted, charge fully before using again to maximize battery life.

Optional Attachments

The Included G Battery functions interchangeably as the power source for the G Coil, Essential Oil Tank, Aromatic Blend Tank, and Hookah Tank. The G Battery is only compatible with Grenco Science products.
