G-Pen Pro Vaporizer Review

Grenco Science has released a new version of the G Pen Pro, complete with a much smaller size and a very attractive price. There are not many comments yet, but we’ve already seen comparisons.

How It Works?

If you are looking for a revolutionary new design, keep looking. The basic functionality does not differ much from the original G Pro or other cheap vaporizers. For example, there is always only one button and three temperature settings. The camera is located on top of the battery and directly under the nozzle. To activate it, click the button five times. To scroll through the temperature settings, press and hold the button. The current level is indicated by the color of the LEDs. The warm-up takes about 30 seconds. That’s really all there is. It’s very simple, but it’s not necessarily a bad thing if it allows you to sell it for $100 or less.

Temperature Flexibility

The flexibility of the temperature is average for this price range and below average compared to the evaporators in general. There is no fill level screen, just a set of LED lights. The colors and layers are:

  • Blue – 375 ° F
  • Green – 400 ° F
  • Red – 428 ° F

Again, this is not a very large number of options, especially if other similarly priced units like the Utilian 420 offer more, but it will do the job well. I am glad that they have distributed each level around 25 ° F, as this will allow you to achieve a wider range of steam preferences.


The quality of the vape is the most important part of a vaporizer, and the good news is that this new G Pen Pro represents an improvement over the original in this department. That means it’s really not hard to reach. The quality of the vape was never the strength of Grenco. So, although the vape is better, it’s still not great. The taste is good at the beginning of a session but falls off quickly. It’s hot, but not as hot as the original. The general vape production is average. You will not get a ton of visible vape or extremely heavy shocks for that, but it’s more than enough to do the job. It is certainly not compared to devices that have glass jets.

The build quality is also pretty average. I like the exterior to be aluminum, but I’m not a big fan of the plastic nozzle. They contain a silicone skin to help with overheating problems, but they will warm up after a long session. The biggest improvement is certainly the size. It is much smaller than the original. The elite is even shorter, but not much. The biggest improvement is certainly the size. It is much smaller than the original. The elite is even shorter, but not much. The size is obviously why they make comparisons between him and the Pax 3, but it’s much higher than the Pax.

Battery life

It has been difficult for me to decipher this because it cannot be found in the manual or on the website, but I think the battery has a capacity of 1300mAh. I could get about 40 minutes of uninterrupted use of it. Depending on the temperature level you use, you can get something more or less. It is fully charged in 2 to 3 hours.


The portability is excellent. The dimensions are 116x25x24mm. In other words, it is very small. The aluminum exterior and the lack of a screen also make it very durable. You should be able to take it with you practically anywhere as it fits in a bag and does not tear.

User Friendliness

This is extremely easy to use. With a single button and three temperature settings, a complete beginner could take that and start using it. The only thing you should remember is that five clicks will activate it and holding the button down will adjust the temperature.


I will conclude my review of Grenco’s G Pen Pro with a sentence that I have used several times in this review: It does the job well. It’s better than the original G-Pro, but it’s not a very high bar to overcome. I’m not sure why people are so excited. I can already hear people complaining that I’m not right because the G Pen Pro is a lot cheaper. That’s right, it can be a bargain for $100. But at the same time a unit like the Utilian 420 sells for less than $ 10, has a glass nozzle and a digital display. 2 Characteristics that were hard to find in Grenco’s household units. Although the G-Pen Pro may have a better price, it still does not offer the best features in this price range.

    […] Although there are similarities between these two vapes like size, battery operated and discretion, most are differences between them. Price can be different too because dry herb vapes generally cost more. […]
