G-Pen Hyer is a uniquely designed E-nail that can transform your bong into an electric rig. It comes in a hemp-made travel case, ensuring safety when you take it on the go. You can use the G-Pen Hyer with any glass bong or other material.

Moreover, G-Pen Hyer is for you if you love to smoke or vape but are tired of using traditional lighters, torches, and hemp wicks to light up your herbs or concentrates. It keeps the flavor clean and pure because the herbs will not directly contact the fire.

what is in the g pen hyer box

The following stuff is included inside the package:

  1. Quartz concentrate tank
  2. Concentrate carb cap
  3. Housing component 
  4. Battery component 
  5. 14mm glass adapter
  6. Power cord
  7. USB-C cable
  8. The stainless steel loading tool
  9. Hemp traveling case with mesh pockets


The G Pen Hyer Vaporizer is an e-nail device specifically used with a glass bubbler. It is compatible with all 14mm bubblers, but you can purchase other adapters to adjust accordingly.

Other than this, the material you can smoke with the G Pen Hyer Vaporizer can be either dry herbs or concentrates (depending on your tank).

The company has made it a dual-purpose device, but the usage depends on the tank. We have discussed the tanks and other prominent components in the coming headings. 


The G Pen Hyer Vaporizer might feel like a very complex e-nail, but it is easy to get along with once you know the components. There are five main components on which the device operates. These components are as under:


Carb cap 

You will first encounter a carb cap while using the G Pen Hyer Vaporizer. The lid of the heating chamber seals the tank to ensure the material is not exposed to the surroundings.

Two kinds of carb caps are available for dry herb and concentrate smoking. These carb caps are made of aluminum alloy, so they are durable. A dual airflow insert (holes) is designed for good air passage during heating.

The concentrate carb cab comes in the package, while the dry herb cap is sold separately. The carb cap also has an aperture to insert and fix the stainless steel wax tool. There are two positions where you can rest this tool. 


The tank rests beneath the carb cap. Inside the tank is where the heating chamber is situated. The heating element is made of ceramic or quartz to ensure that the herbs or concentrates are not combusted.

There are two different tanks used in the G Pen Hyer Vaporizer. The dry herb tank has a ceramic chamber, so the taste will never change throughout the sessions. 

On the other hand, the concentrate tank has a quartz chamber surrounded by an aluminum layer. This layer directly heats the heating element and reduces the heating time. 


Housing has a simple function. This component houses the tank and allows you to connect other components, such as the battery, carb cap, adapter, etc.

The housing component is made of pure aluminum alloy that is durable as well as lightweight. A modular fit feature enables it to fix the diameter according to the size of the adapter. 

Glass adapter

Below the housing component, you have to connect a glass adapter. This glass adapter lets you connect the device to a glass bubbler or other filtering devices.

The box will include a 14mm male glass adapter that is a market standard. You can also purchase the 10- and 18-mm adapters sold separately. 


The battery is not fixed on the device. It is connected to the tank via a braided cable. However, we will discuss the battery features in the later headings. 

Heating chamber

As we discussed earlier, the heating chamber is inside the tank. The heating element of the dry herb is made of ceramic, while the concentrate is made of quartz. The chamber is around 16mm in diameter, while the total capacity is 0.5 grams

. This quantity is enough for long sessions. Ceramic and quartz have zero risk of burning the material, so you will never experience a metallic smell amidst sessions. 

Heating time

The heating time is not something that you should worry much about. The heating time of the dry herb tank is 15 to 25 seconds because herbs take less time to heat.

On the other hand, the concentrate tank takes around 15 to 45 seconds to heat. Concentrates usually take more time to heat, which has nothing to do with the tank’s efficiency. 

Heating method

The heating method used in the G Pen Hyer Vaporizer is pure conduction. The company has retained the classic heating method because it is efficient. There is no risk of combustion, especially because the heating element has no metallic intervention.

The carb cap has some holes for better airflow, but more is needed to make it a convection vaporizer. The conduction heating system is one of the main reasons this device has such a short heating time. 

Temperature range

The temperature range is entirely dependent on the tank you are using. The dry herb tank has a range between 180 and 220 degrees Celsius. Dry herbs can cook without an excessively high-temperature range.

The concentrate tank has a range between 250 and 450 degrees Celsius. Concentrates and oils are less prone to combustion. The temperature range is increased here to ensure demanding users enjoy high intensities.

Temperature settings

The temperature settings incorporated inside the G Pen Hyer Vaporizer are made simple for those who demand ease or the ones with the less vaping experience. The G Pen Hyer Vaporizer has five intensities which no doubt restricts the user’s control over the device’s operations.

However, the ease of toggling between the intensities is something you will admire at some point. The intensities remain the same in the dry herb and concentrate tanks. 


The G Pen Hyer Vaporizer has a very simple operating mechanism where you must know how to assemble the component. Once that is done, the rest is straightforward. The battery component will guide you throughout the usage. It has five LED indicators to depict the intensity that you are hitting.

Three buttons make the controls simple. You will find a power button alongside two arrow buttons to toggle between the intensities. Other than this, the five minutes automatic shutoff timer makes it a safe product to use.  

Power Features

The G Pen Hyer Vaporizer has a separate battery. No battery is fixed or installed inside the other components because that would have made the device bulkier. The tank, carb cap, and housing components are all very compact.

Fitting a battery inside such components would have forced the company to compromise on the battery size and capacity to maintain the device’s compactness. 

The battery is 6000 mAh, which is a tremendous capacity for an e-nail. It is rechargeable. The company has integrated a USB-C charging port that has 3-ampere current compatibility.

It charges in just 2 to 3 hours. It is an efficient time for a battery with 6000 mAh. It provides 20 to 25 sessions in one complete charging cycle. 

The batter component looks like a chunky and heavy device, but the company has enclosed it inside a premium aluminum shell to ensure it is as light as possible.

The charging is passthrough, so you can use the battery while charging. It is connected to the housing component with the help of a braided cable, and the cable is connected magnetically. 


Portability can be a major issue with the G Pen Hyer Vaporizer. This has nothing to do with the housing component of the battery. All the components mentioned in our article can fit inside the traveling case.


The battery also has a massive capacity to carry it anywhere. However, the biggest blow to the portability is the inability to use this device without a glass bubbler.

No matter what you do, you can only smoke by attaching the G Pen Hyer Vaporizer to a glass bubbler. Carrying a bubbler can be very problematic since it is larger and prone to breakage.


The G Pen Hyer Vaporizer comes with the same one-year warranty, a common policy for all the products produced and developed by Grenco Science. This provides ample time to experiment and test the quality of the G Pen Hyer Vaporizer.

Final Verdict

If you are a fan of glass bubblers and water filtration of vapors, then the G Pen Hyer Vaporizer is one of the most convenient and superior products on the market. The concept of separating the battery from the main component is a well-thought feature.

The G Pen Hyer Vaporizer might seem like a high-end product, but it is not the most luxurious vaping device you would come across. It costs around 250 dollars. This is a fair price for what the company has on offer. Try the G Pen Hyer Vaporizer if you demand quality and convenience.
