Loading the G Slim Vaporizer

Having a stylish and sleek design, this conductive vaporizer is as easy as possible. Before the first use, fully charge the vaporizer battery. To do this, unscrew the tank from the battery and screw the battery into the USB charger. Then, fill the herbs inside of the heating chamber so that the heating element in the form of a spiral is covered completely. Then, returning the mouthpiece to its original position and securing it, activate the vaporizer 5-fold by pressing a single button, located in the middle part of the body. Finally, continuing to hold the button down, begin vaping.


Remove the mouthpiece of the vaporizer G Slim, slightly swinging it. Use a supplied tool for cleaning the herbs from the chamber. Bear in mind that it is made of glass, so be careful while cleaning. Once cleaned, the device is ready to use.


Before cleaning, make sure the device is switched off, and the chamber is cooled down. Only after this, start cleaning the chamber. Use only the special tool provided for cleaning the herbs. Do not use water or other liquids for cleaning. Disconnect mouthpiece and clean it as well, including filter. Once every part of the vaporizer is clean and dry, connect all of them back together.

G Slim Ground Material Vaporizer: Vaping or Combusting


The vaporizer has a built-in heating element that warms up the ground material in a few seconds. This technology allows evaporating only active and useful substances. This eliminates harmful effects of tar in the lungs.

And this is not the only plus of G Slim Ground Material. The vaporization process has no direct contact with fire and heating elements. As you know, the traditional smoking performs with a use of naked flame, and up to 80% of active and useful substances are destroyed. As a result, you get only about 20% of active substances. Using the G Slim vaporizer, users get 100% of active ingredients!


The device has a Li-Ion battery with a capacity of 650 mAh. The USB charging allows to recharge it during the day. Depending on the use, the vaporizer is working up to 4 hours since the last time of full charge. Because it has no temperature modes, vapers will not be able to set the lower temperature and prolong the battery life.

G Slim Hookah Vaporizer

This hookah vape pen by G Pen makes vaping e-juices as easy and tasty as it gets. Enjoy all the flavors and nuances of favorite e-liquids without worrying about atomizers or coils. The quality of the vape pen, plus the performance made this a great vape pen for the beginner and experienced alike.

The G Slim Hookah Vape Pen is compatible with G Slim Liquid tank from Grenco Science. The tank is simple-to-use and it fits perfectly with any product from the G Slim line. Using the e-liquid tank with most G Slim vaporizers with their fantastic, no hassle features, no need to struggle with resistance levels or coils compatibility.


The decent tank has a capacity of 0.6mL, and 510 threading fits directly into any G Slim battery. With this product, one can get enough puff to last you several vaping sessions with a fantastic experience. Grenco Science is well-known for its ability to produce an incredible product that beginners can find easy to use and enjoy quality vaping with appropriate throat hit. It has about 6 – 8 weeks of durability.


Start by charging the pen. The process is simple, just remove the atomizer and screw the battery into the USB charger and plug it into a USB port. Once it is charged, dab a drop of e-juice or oil onto the atomizer. This will prime the wick so it will start vaping smoothly right away.

Next, fill the chamber with the preferred e-juice. Thin liquids work best here.
The window on the side will show how much to fill. The chamber is 0.6mL, so not too shabby considering how small the pen is. Screw the tank onto the battery and click the start button five times to turn it on.



The atomizer is set to vape thin liquids, so the liquid should either be higher PG to VG or if it is a high VG, should be thinned. If using a high PG juice, expect a decent throat hit while still tasting all the flavors of the juice.
A high VG juice that has been thinned should still keep all the flavors, but also that depends on how much it is diluted with water. A 50/50 blend that combines a light throat hit with some thick vapors will work well, too. Either way, the pen performs great and vapes very smoothly.


The Snoop Dogg Bush G Slim was created in collaboration with the excellent Grenco Science vape company, so the Bush G-Pen is assured to be a high-performance device. This liquid vape pen was inspired by the release of the Snoop album that accompanied its production. The “Bush” in the title refers to said album and rather than being a typical dry herb vaporizer, this slim and lightweight device is a dedicated vaping device for oils and concentrates.

Its operation and use are very straightforward. Unscrewing the atomizer from the battery reveals the small coil and wick inside, which will probably last anywhere between 6-8 weeks. When loading the chamber with concentrates make sure not to touch the exposed wick section with the loading tool, as it might break. After loading the chamber with a few dabs of concentrates, screw the two back together and then reattach it to the battery.

Five clicks of the button turn it on, and five clicks turn it off, which will light up the LED light at the base of the battery. Once the device is turned on, push the fire button and take a hit of vapor from the slim, flattened mouthpiece. There is a metal screen right underneath the mouthpiece to provide an extra layer of filtration to purify the vapor. The device fires right away, and the vapor production is excellent.
