Grenco Science is proud to present the G Pen Vaporizer, a simple and convenient vaporizer for your favorite oils/concentrates. The G Pen is very easy to load, use and clean. Its pen style aesthetic makes it one of the most discreet portable vaporizers on the market. The G Pen’s virtually instant heat up time provides vapor enthusiasts with satisfying results at the push of a button.

G Pen


Every G Pen battery comes charged out of the box so all you need to do is unscrew the plastic storage cape, load your desired concentrate into the G Tank, and reattach the cap and mouthpiece. You’ll be enjoying sweet tasty vapor within minutes of opening up the G Box!


Grenco Science wants your aromatherapy practice to be as hassle-free as possible. This is why the G Pen is a stand-alone unit. There are no confusing directions or tiny pieces to assemble before using your vaporizer. The G Pen can be unlocked by pressing the button five times in succession.


The G Pen is designed specifically for liquid and solid concentrates. Known colloquially as “oils and waxes,” these ingredients are growing in popularity and Grenco Science took all important variables into consideration when they set out to construct the perfect pen vape. Factors like temperature, weight, consistency, average density and appearance were all considered with utmost care to create an oil vaporizer that is convenient for novices to water vapor pens and gratifying for the most discerning vapor connoisseurs.


The G Pen should be cleaned on a regular basis in order to maximize functionality. We recommend using a clear alcohol solution to clean the screw threads in the G Pen’s atomizer; this ensures consistent electricity runs to the device. Let your G Tank dry before re-attaching for use. Make sure you let your battery charge completely before use in order to maximize the life of the battery.

Note: This unit is only compatible with Oils/Concentrates - No herbs.

    The pen works well. But the screen it comes with gets clogged within the first couple of uses, so I've had to turn mine into a straight shooter. It's a little complicated to pack wax onto the coil, due to the glass that surround it is too high and makes it hard to reach the coil.. But other than that the G pen is working like a champ. To clean it I turn it upside down and turn it on so the wax will melt right off .

    Works okay...gives you small, yet smooth hit once loaded. But seems like you will never get all the oil off it...but you can dab right off the coil for a massive hit.

A: We recommend that you let the unit charge for at least 3-4 hours before first use.

Q: Does this pen include some oils?

Asked By Andree on August 22, 2012

A: No. Unfortunatley, the G Pen Vaporizer does not include any oils with the unit.

Q: Do these style vaporizers only work with oils? Or can you use herbs as well?

Asked By G. on August 03, 2012

A: The G Pen Vaporizer is only compatible with oils - no herbs. However, other "pen-style" vaporizers like the Pulsar 7 and AtmosRaw are capable of vaporizing herbs.

Q: My G-pen continues to blink, stating that it is locked, but will not stop once repeatedly pressed 5 times. How can I fix the locking mechanism?

Asked By Aaron on July 21, 2012

A: No need to fix the locking mechanism. This usually indicates that the battery is low and needs to be re-charged. The G Pen should blink approximately 8-10 times when this occurs.


Quick Instructions:

Step 1: Make sure all components are delivered with your G Box.

Step 2: To charge your battery using a wall socket, plug the USB Charger into the provided AC Adapter.  Battery LED light will flash 3 times and remain lit on the 4th flash until your battery is fully charged. The USB charger indicator light will switch from red to green once the battery is fully charged and the AC adapter will display a red light when there is sufficient power from the power source. Please allow 8 hours to fully charge for the initial 3 charges.

Step 3: Using the provided G tool, remove the rubber cap from the top of the tank. Your authentic G tool is perfect for carefully inserting Essential Oil/Wax into the G tank.  The rubber cap is for storage purposes only and can remain off until you store your G tank for a long period of time.  Once you have reached your desired amount, insert the metal casing over the tank until it snaps into place. Once this is done, you are ready to screw the assembled G tank onto your fully charged G battery and vape!

Step 4: The G-Pen is engineered with a locking mechanism so it doesn’t turn on in your pocket or purse. To lock and/or unlock, rapidly press the button 5 times. The battery will acknowledge it is locked or unlocked by blinking it’s LED light 3 times. Once it is locked, you can place your G-Pen anywhere with the comfort of knowing it won’t vape in an undesired location. Once unlocked, you can press the button to start enjoying your G-Pen Vaporizer!
