How it Works

This G Pen Herbal Vaporizer comes pre-charged and ready for use. Just unscrew the plastic storage cape. Then load the herb into its tank. Once that is done, reattach the cap and mouthpiece.

Operating this pen is easy since this is a stand-alone unit. There are not many settings to adjust. Like most vaporizers, you can turn on this vape pen by pressing the firing button five times. Hold the button steady to engage the heat. That’s the only thing you need to do to operate this device.

The G Pen looks like any a normal vaporizer. Although it is small, the performance of this Grenco Science device is impressive.

Cleaning G-Pen

You need to clean this pen regularly to ensure it lasts longer. Apply a clear alcohol solution to clean the atomizer’s screw threads. This will also ensure you get an uninterrupted supply of electricity to your device. Dry the G Tank first before reattaching it after cleaning. Even then, you’ll need to change the tank every month or so.
