This LA-based company was the first to introduce a tank system for oil concentrates to the vape market, which later became an essential feature of most vaping pens.

Grenco has been developing and selling user-friendly vaporizer devices since 2012, collaborating with influencers in the vaping and weed industry, like Snoop Dogg for example.

Besides the Elite device, I’m going to review in this article, Grenco also offers G Pen Pro, G Pen Gio and the original G Pen, as well as a bunch of different accessories.

According to Grenco, G Pen Elite is their best selling product, however, the experiences of users are mixed, ranging from bad to good.

My experience with G Pen Elite is also a mixture of both bad and good things, so I wanted to do a write-up and share my thoughts on this device.

What’s in the G Pen Elite box?

G Pen elite box contents

In the round, unique, nicely designed box, you’ll find:

  • G Pen Elite vaporizer
  • One G card
  • G Pen tool
  • USB charging cable
  • One cleaning brush

To be honest, at first, I was a bit disappointed as I expected to find more accessories. These are just the essentials, which is fine considering the price.

Everything else you need to buy separately: silicone sleeve, different mouthpieces, charging dock, USB charger…

And now when I come to think about it, it’s not a bad idea at all. The device itself costs $150 (which is quite cheap for a vaporizer kit) and you can basically personalize your kit by buying accessories you are really going to use.

This way you won’t end up with a bunch of extras you are never going to use.

Battery life & charging options

G Pen Elite has a 2200 mah Li-ion internal battery, which needs 3 hours to fully charge using a USB cable from the box. If you’d like a faster charging time, you should get a charging dock as an extra, right from the get go.

Depending on the temperature you are going to be vaping at, and how well-cured your weed is, you’ll be able to pull out between 4-10 sessions on one charge.

The one thing I particularly liked is that you can easily check your battery life on the LED display. Battery is shown in the form of bars.

The battery is neither removable nor replaceable.

That means if something happens to the battery and it dies, there’s nothing you can do—except just throwing the whole device away.

Flower, concentrates or both?

G Pen Elite unit is compatible with dried herbs only.

It’s not compatible with concentrates, so if you are not a big fan of dabbing, this is a product for you.

If you like to treat yourself with concentrates from time to time, you should try out any other device suitable for both concentrates and dried herbs.

G Pen Elite heating

G Pen Elite temperature control

G Pen Elite is very flexible when it comes to controlling the vaping temperature. You can easily choose any temperature between 93-220°C just by pressing up and down buttons, so you have the complete control over your vapor.

The exact temperature is shown on a neat, little LED display. You can even switch between Fahrenheit or Celsius.

Here’s a quick tip: To change from Fahrenheit to Celsius hold the power button and the up arrow at the same time. To change it back to Fahrenheit hold the down arrow and the power button.

The G Pen Elite’s temperature range is more than fair since it’s a herb-only device. You can play around with it and see what temperature produces the best vapor for you.

In my experience, that depends on the strain you are going to be using.

The recommended temperature for dried ground weed is somewhere between 175 and 190°C, but you can turn it up of course if you prefer. Keep in mind that the device gets really warm, especially on higher temperatures. The mouthpiece can get hot, too, particularly at the end of your session.

Once you set the temperature, the G Pen Elite takes about 20 to 30 seconds to warm up, which is pleasantly quick.

G Pen Elite vapor quality 6/10

The quality of the vapor on the G Pen Elite is fulfilling. Since you have full control over the temperature, that also means that you have full control over the vapor, too.

But in general, the vapor is smooth and consistent. The ceramic chamber heats the herbs evenly so it provides a rich and tasteful flavor.

The airflow is fine, but the heating chamber is right under the mouthpiece, meaning there isn’t much time for vapor to cool down, which makes the vapor a bit harsh and dry—this may be unpleasant, depending on your vaping preferences.

G Pen Elite design 7/10

This device looks OK, but I am not impressed, to be honest.

G Pen Elite design

It only comes in black (they did have two special editions, but they are not available on the manufacturers’ website anymore). Maybe this has something to do with my taste, but I’ve seen better-looking vaporizers in the same price range.

However, there are a few things about the design that makes this device stand out. Although I don’t like how it looks generally, I have to admit that the design is actually functional.

First of all, it’s the ergonomic shape that makes it super comfortable to hold and use. The curves make it perfectly easy to wrap your fingers around the gadget, giving it a natural hold of sorts.

The G Pen Elite’s dimensions are 4.5’’x1.5’’x1’’ and since it’s made of fine plastic it’s pretty light—weighs only 88 grams.

Its discreet size means that this G Pen will easily fit in your pocket or purse.

How to use G Pen Elite


Before you use your vaporizer for the first time, you would want to sterilize it to remove any harmful substances and the smell from the manufacturing process.

To do this with the G Pen Elite, press the power button five times (this was a little odd, though).

Then, press the up arrow button until you hit the highest temperature. To begin the heating press, hold the power button and let it run. The device will automatically turn off after five minutes.

To complete the process, repeat this two more times.

Filling it up & chamber info

The chamber of the G Pen Elite is actually huge and you can pack as much as 0.75 grams of weed in it.

This is probably the largest chamber on the market. While this is a perfect chamber for a vaping sesh with your friends, we can agree that it’s too much for a solo vaping experience (considering that about 0.2 grams are enough for one solo session).

G Pen Elite does not come with a half-pack oven lid like the Pax 3 for example, nor is there any solution for it.

Getting started

The device is so easy to use and even the novice users won’t have any trouble getting started.

Here’s how you use it:

  • Take off the mouthpiece, pack the chamber with ground weed, and put the mouthpiece back.
  • Once you’ve done that, hit the power button quickly five times to turn the LED display on. Select the temperature by toggling the up and down buttons.
  • Now, hold the power button once again. You’ll see how the warm up progresses on the LED screen. When it warms up to the desired temperature (about 30 seconds), you can start drawing.

Cleaning and maintenance

G Pen Elite should be cleaned from time to time, to ensure maximum lifespan.

To clean the mouthpiece, just take it off, pull off the silicone cover from it as well as the filter screen. Soak these parts into alcohol for 20 minutes and then let them dry for another five minutes before assembling the device again.

With the cleaning brush included in your G Pen Elite box, you can clean the inside of the heating chamber, mouthpiece connections and the filter screens.

G Pen Elite standout features?

Grenco offers one year warranty for the G Pen Elite, which is a horrible warranty considering that this vape costs $150.

Since it also has a non-replaceable battery, we’re potentially entering a world of trouble, but, we’ll see how long my G Pen Elite is going to last—I will be updating this article.

A few upsides are the flexible temperature regulation and an ergonomic design, but are those two really worth this much money?

Final Verdict


Hundred and fifty bucks is a bit steep for an average vaporizer, which is what G Pen Elite is in the end. The box comes with a vaporizer and just a few essentials, which means that you need to buy additional accessories, and so I’m giving it only 6 out of 10, acknowledging that there are better deals on the market at the moment.
