Grenco Science G Pen
The G Pen Elite vaporizer is a new portable dry-herb vape from Grenco Science. Smooth and sleek, this device is a portable conduction vaporizer powered by a lithium-ion battery with smart-chip technology that makes it perfect for vaping on the go.
Grenco Science G Pen Elite Testing and Performance
There have been a couple of versions of the G Pen. The G Pen Pro is the earlier version which had a smaller oven capacity and pre-set temperature settings. The G Pen Elite is the upgraded version with a larger oven capacity and the ability to customize your heat settings by pushing the buttons up or down.
Build Quality and Design
The quality of the device seems to be pretty solid. It has a bit of heaviness to it which suggests it is solid and sturdy. The design is different than most vaporizers of this size. It is about the same height as the Mighty. It is shaped more like a bullet with smooth cut out sides which make it very easy to hold and grip. The texture on the outside is smooth with rubberized grips on the sides. It feels very smooth and fits nicely in your hand.
In all honesty, it really does not look like a standard vaporizer. To me, it resembles a beard trimmer or a shaver of some kind. That is just what I think of when I look at the device. I don’t think anyone would know it’s a vaporizer unless you told them. It is small enough to slip in your pocket or purse and you can vape it in stealth mode.
The G Pen Elite is well-made and sturdy. It isn’t top-heavy so there is no worry of it tipping over or rolling off of smooth surfaces. There are no breakable parts to this device. Nothing to crack or chip if accidentally dropped.
The battery life for the GPen is about 90 minutes to an hour of continuous vaping. Once the battery is completely drained it takes about 2 hours to be fully charged. It charges via USB cable and can be plugged into a laptop or wall charger. You will need to let it charge for about 3 hours when you first get it because it does not come pre-charged.
I was actually surprised at how to use this device is. It has a very simple one-button operation and the ceramic oven is one of the largest I have seen yet. It is very deep but you don’t have to pack it very tightly so it doesn’t have to be full to use by yourself.
To fill the chamber you first need to remove the mouthpiece as the oven sits underneath it. To remove it grip the mouthpiece and gently move it back and forth in a rocking motion until it is loose enough to pull it off. Place your ground herbs inside the chamber and lightly pack it with your finger or the included packing tool. It doesn’t have to be packed tight in there just press it down and it’s good.
It also uses the standard 5 clicks to turn it on and off like similar vaporizers. To start the heating process, you press and hold the power button for a minute and you’ll see the temperature changing in the LED lights on the side of the device. It takes about 30 seconds to reach the desired temperature and you can adjust the temperature up or down using the buttons located on the side of the device.
Cleaning the G Pen is also pretty easy. You just remove the mouthpiece again and dump out the contents of the oven. Using the included brush, sweep the inside and the outer edge of the oven chamber. You can wipe out the inside with a cotton swab dipped in isopropyl alcohol. Clean the mouthpiece with a cotton swab to remove any ground material from the screens.
It is one of the easiest devices I have ever used. There is literally nothing to it. Even a beginner can get great results the first time around. It produces a surprising amount of vapor in the higher temperature ranges. It has just the right amount of resistance in the draw. The first couple of draws you won’t see much vapor but it increases as it warms up. About the third or fourth draw, you should get a pretty decent cloud. I like to spend most of my session with low heat (375 to 380) but more flavor and then bum it up (400) at the end to finish it off with more vapor production and to ensure even vaporization of ground material.
I also like the fact that the mouthpiece does not get hot as you vape, despite the oven chamber being directly below your mouth. It stays cool and burning lips. The device itself doesn’t even get that hot. It feels warm to the touch but that’s as hot as it gets.
Always remember to carry your devices safely. Let the device cool down before putting in your pocket or purse. Click the button 5 times to turn it off before putting it away. A device that is turned off poses no danger because the battery cannot engage without the device being on.
What We Liked

The G Pen Elite is priced at $149.95 and is worth every penny. It performs very well for a small device and puts out just as much vapor as the bigger units. The fact that it is so easy to use is another big plus. There are no complicated menus, no smartphone apps, just up/down buttons and a power button. Even beginners will be able to use this because there is no way to get it wrong.
I recommend this vaporizer to anyone who prefers simple devices with very low maintenance requirements. Easy to use, easy to clean, and no fiddling with buttons. Just turn it on, heat it up and vape it. It is a good value for the money because it works so well and it’s portable so you can take it anywhere.
