All subscriptions that are started between the 16th and the last day of any given month will automatically have their renewal date moved to the 15th of the following subscription period.

G Pen Nova Vaporizer

Rated 4.7 out of 5
3 Reviews


When it comes to cutting edge vaporizer technology, Grenco Science leads the pack. They recently announced the long-anticipated launch of their G Pen Nova line, a compact vaporizer capable of handling concentrates.

This one-two punch and compact design makes the G Pen Nova a versatile and powerful vaporizer, perfect for those on the go.

The G Pen Nova is powered by an impressive and innovative battery, boasting 300mAh of power and a variable voltage system equipped with a three-stage setting that allows for ease of both operation and customization. The great thing about this battery is that it is also compatible with all standard 510 threaded cartridges, and includes pass-through charging by way of a micro USB port.

But one of the stand-out features of this vaporizer is the use of a dual-use tank, making it simple for users to enjoy their concentrate at their leisure, and an extended draw mode for a superior and exhilarating vaping session.

Featuring a quartz bowl and ceramic heating element, the G-Pen Nova is exceptional at controlled, even heating, resulting in impeccable flavor from concentrates.  

For added convenience, a ceramic loading/stirring tool is built directly into the mouthpiece, allowing users to easily load the tank directly with concentrates.

All these features and more have set the G Pen Nova apart from the crowd, making it one of the most cutting edge and innovative vaporizers on the market. With a sleek, compact design, versatile dual use bowel, and exceptional vaping experience, you won’t want to miss out on this device.


  • Universal 510 Threading
  • Variable Voltage Battery (3.2V, 3.5V, and 3.9V)
  • Integrated Ceramic Loading Tool
  • Pass-Through Charging
  • Ergonomic Silicone Mouthpiece

Works well with crumble

The pen works well. I had two fixable problems with it however. 1, the little dabber tool that’s attached to the top is not good at getting wax out of a container and really just picks up reclaim from the atomizer. I took it off with pliers. 2, the ceramic coil seems to have burnt or there is resin burnt on it, in which case it is my fault for not cleaning it enough.
