G Pen Nova

With the G Pen Nova Grenco Science presents a simple dual-use vape pen that is a great introduction to the world of vaping.

Small, effective but surprisingly versatile, the Nova is an unpretentious vaporizer that has almost no learning curve. A great choice for beginners and vapers that need an easy on the road solution for herbs and concentrates.

G Pen Nova features

  • 300 mAh battery
  • Full ceramic heating element
  • Reverse airflow and check-ball valve system
  • Sesh mode
  • 510 thread compatibility

How to use

The G Pen Nova is really straightforward to use. First charge the vaporizer with the included USB charging cable. The red light means the unit is charging. When it changes to green it’s fully charged. Remember that you can use the Nova while charging.

Load the pen by removing the mouthpiece and filling the chamber with medium ground herb or use the integrated loading tool to scoop a bit of concentrate and just close the mouthpiece with a slight twist.

Activate by pushing the button 5 times in succession. 

Toggle between the three output levels by hitting the button three times in succession.

The Nova also has a “session” mode which comes in handy with for instance thicker concentrate that needs a bit of extra heating. Hit the button two times and the Nova starts to heat continuously. If you are ready just hit the button again and you will exit this extended draw mode.

Extra functionality is provided by the 510 thread. Want to vape with your favourite cartridge? Twist off the upper part of the Nova and replace it with a 510 threaded cartridge. Now you’re good to go with e-liquids.

Important: it’s important to clean the chamber after use of concentrates especially if you’re into dual use of the Nova. A quick rub with an alcohol wipe or iso swab will ensure perfect functionality.

G Pen Nova settings


The Nova has three settings which correspond to three different voltage levels:

  • 3.2 V (low)
  • 3.5 V (medium)
  • 3.9 V (high)

With dry herb, you can play around with all three levels and see what fits best with your material, grind and taste. For concentrates, it’s best to use the highest setting.

What’s in the box

  • 1 G Pen Nova Battery (510 Thread Compatible)
  • 1 G Pen Nova Tank
  • 1 USB Charging Cable

VapoShop Verdict

The G Pen Nova obviously is an affordable entry-level vaporizer which lets the vape curious discover the possibilities of vaping. The Nova may look simple at first sight but it cleverly offers a number of functionalities without adding any frills. It also works as a nice second vaporizer that it’s easy to take with you.
