G-Pen Pro

G-Pen Pro

Grenco Science has dropped the G Pen Pro the newest addition to the G Pen Series. The dry herb only vape states on the front of the packaging “For Ground Material” and in the instructions strictly states “Not intended for use with tobacco, liquids, or concentrates” The design is similar to it’s brother the G Pen Elite but it’s a way smaller vaporizer. Priced at around $100 the pro is $50 cheaper than the G Pen Elite.

What’s in the Box

  • G Pen Pro Vaporizer
  • G Pen tool
  • USB charging cable
  • Cleaning brush
  • Instructions



Identical to the G Pen Elite in almost every way but size, the G Pen Pro is a small sleek, discreet matte black finished vaporizer that is perfect size for portability and can easily be carried in a pocket or purse. The G Pen Pro is easy to use its mouthpiece removes to reveal the oven/chamber like the design on most devices including it’s brother the G Pen Elite. It’s all ceramic chamber/oven can hold up to .2 grams of ground dry herb per session. Although the G Pen Pro might resemble the G Pen Elite in ways, in other ways it doesn’t. The G Pen Pro doesn’t have precision temperature control with digital temperature display like the G Pen Elite does. The G Pen Pro has 3 temperature presets:


Blue = 375 F / 190 C

Green = 400 F / 204 C

Red = 428 F / 220 C


Ease Of Use

The Grenco Science G Pen Pro is powered on the same way as most devices you simply press the power button 5 times rapidly. Before powering on the device pack about .2 grams of ground dry herbs loosely not too tight to where as it will block the air flow. To cycle through the temperature settings of the G Pen Pro hold the power button while the device LED lights will change to the color of your preferred setting. Once you have selected a temperature setting the LED lights will blink and become solid once the device is heated to the desired temperature then you are able to draw from the device and enjoy.


Vapor Quality

‘The G Pen Pro also performs like the G Pen Elite in vapor quality. They are both similar in the fact that there is very little draw resistance while using the device meaning you don’t have to pull hard when taking a hit. The taste of the vapor isn’t ideal after the first couple of hits and the product burns way faster in the G Pen Pro as opposed to the G Pen Elite. I believe that this comes down to the precision temperature control that is available with the G Pen Elite. The ability to start your sessions at a low temperature with a gradual increase as you vape to the higher settings increases the length of sessions as well as the flavor. I would have to say that’s probably the biggest difference in the units that would make you want to spend the extra money to purchase the G Pen Elite.


Battery Life

The G Pen Pro has an automatic shutoff that enables after 4 minutes from powering the device on for use and can be helpful in preserving the battery. The battery can last for about 45 to 60 minutes of continuous use, that’s about 11 to 15 sessions averaging each session at 4 mins long. The G Pen Pro takes about 2 hours to obtain a full charge and the Micro USB charge port is located at the bottom of the device.

Final Thoughts

Overall the G Pen Pro is a watered-down version of the G Pen Elite and if you are getting it for the price difference the Boundless CFC would in my opinion would be a better option at the same price range. It’s not the worst vape in it’s class but it’s not the best either you could get money for your money or spend a little more and get more ba
