Grenco Science, the manufacturer of remarkable and ultramodern vaping pens, have released another successful product into the vaping market. The engineering giants keep producing more revolutionary products that are user-friendly. They meet the constant demands of their highly esteemed customers all over the world. The G Pen Pro Vaporizer was specifically designed to use together with dried herbs. This vaporizer is packed with stylish features that make this the crème de la crème.

Ease of Use

The G Pen Pro is quite easy to use. The manufacturers have ensured that they do everything within their capabilities to reduce the burden of confusion associated with unboxing new products. You can easily power up the G Pen Pro or turn it off. You can regulate the temperature just as easy.
This portable herbal pen turns on on manually. It has an automatic shut off system that powers it off after 4-5 minutes. LED lights located on the side of the vaporizer tell you the temperature you have selected.


The G Pen Pro vaporizer has a distinctive discreet design. This vaping pen comes in a black color which is not conspicuous, unlike many other vaporizers that are usually eye-catching. Take the temperature to the lowest and take quick draws whenever you are in a public place. You can place it on your desk and it won’t look obvious.


The G Pen Pro from Grenco Science is a portable dry herb vaporizer. It boasts a sleeker and stronger version vapes that are compact built. The G Pen herbal vaporizer has color-coded LED display. The large ceramic heating chamber gives vapers the ultimate vaping experience. This makes sure you don’t need to load it often.

Build Quality

The G Pen Pro dry herb vaporizer comes in a black cylindrical tube resembling a cologne.  This cylindrical tube contains the G Pen Pro and accessories which come with it.

The Pro dry herb vaporizer is very sleek, portable and sturdy. The pen’s dimensions are 116mm by 25mm by 24mm which makes it very handy to take along with you anywhere. The exterior part of it is made up of aluminum which makes it unbreakable. It’s mouthpiece is made of silicon to prevent it from destruction and also to permit ease of cleaning.

The interior chamber comes from ceramic material which acts as an oven that can take about 0.25g of herbs. There is a stainless steel covering between the mouthpiece and ceramic oven. It prevents dried products from entering your mouth during a vaping session. The set of LED lights also show the percentage of charge on the gadget. The mouthpiece made of silicon is above the ceramic atomizer where the herbs are packed. The battery is placed below the ceramic chamber and other parts of the pen. The base of the device has a port where you can plug the USB charger.

Another unique feature of the G Pen Pro is its convection heating technology. This feature is quite rare on compact built vaporizers. Users can enjoy flavorful taste of their favorite herbs as the G Pen sends the hot air to the chamber to vaporize the materials. The chamber also assures users of safe vaping because it has low conductivity. This means it won’t get too hot or burn your herbs.

Vapor Quality

The G Pen’s Pro vaporizer gives an average vapor quality. The device heats up pretty fast even when the temperature setting is at its lowest. The vapor quality and taste do not have any unique quality compared to that of other brands. When using the vaporizer for the first time, it is imperative to allow it run through about two heat cycles before you load your material into it. This will burn off any of the manufacturers oil, if any.

The draw resistance is great. The airflow passage is built below the mouthpiece. If the chamber is loaded to the brim, the draw resistance becomes very poor. Try to pack about 30% of the herbal chamber capacity.

Battery Life

It takes an average of 2-3 hours for the battery of the G Pen Pro to charge. The 2200mAh, 7.77Wh lithium-ion battery has a warranty of 1 year. The set of LED lights located at the side of the device show the battery life. If all four LED lights are on, it signifies a full battery. If only two LED lights are on, it means that the battery is low. To charge, the device should be plugged into a source of electricity.

The mini USB cord connects to a PC to charge or plugged into an adapter connected to a wall socket. A turquoise colored light indicates the device is charging. G Pen pro’s battery life is relatively good. It can withstand about 8 sessions at an average of 2 minutes per session. An average session consists of approximately 10 draws. It can last an average of 36 hours after undergoing these sessions.



How to use the G Pen Pro

Loading the Pen

If you want to load the G Pen Pro dry herb vaporizer with dried herbs, pop off the mouthpiece. Put in your semi-powdery dried herb into the oven chamber. Give the vaporizer a light shake so that the material can settle in properly. Avoid overloading the oven chamber to prevent restriction of airflow.

Turning On and Using the Vape

To power the pen on, press the button five times in a quick succession. The G Pen Pro’s default temperature is Blue. If you wish to regulate it to a higher temperature, you can either change it to Green (400°F) or Red (428°F). Press the button until the temperature regulates to your preferred temperature. The LED lights signify the temperature settings you have selected. If it stops blinking at intervals, it means the oven chamber is already heating up to your required temperature setting. When the LED light becomes stable, it means the G Pen pro device has been pre-heated, and you can go ahead to take draws.

Temperature settings

The temperature setting which signifies Green (400°F) produces the best vapor with top-notch quality. It takes approximately 30 seconds for the G Pro pen to attain this particular temperature setting. You have to take at least three draws before the dried herbs in the oven chamber become hot enough to produce vapor clouds.

Temperature Settings

  • Low (Blue) 375°F
  • Medium (Green) 400°F
  • High (Red) 428°F

Cleaning and Maintenance

If you love a very clean pen, you will enjoy the G Pen Pro dry herb vaporizer. This vaporizer is very easy to clean. It is important that you clean your vaping pen every day to avoid clogging of the mouthpiece. This will allow you to have amazing sessions. The cleaning brush does the job of cleaning effectively. Open the mouthpiece at the top of the pen and start cleaning. Put the cleaning brush into the chamber and clean gently. Ensure that every leftover herb is wiped away.

    I had the g pro and it was the best even though it tasted like plastic a bit from the mouthpiece. This is SOO much better. I love it and its so clean

  2. Jake Tovlahd:

    I had the micro g pen for 2 years but was getting tired of vaping wax. I got the G Pen Pro because I like the gpen brand. It’s really good and can easily be custom to your liking.
