The G Slim Herbal vaporizer was created by Grenco Science or as many know them as G Pen. Its design depicts a compact herbal vaporizer taking the resemblance of a writing pen, slim and elegant with its black finish that it could easily pass through any onlooker as pen. The G Slim Herbal only weighs approximately 41 grams, making it easy to slip inside one’s pocket or bag. It comes with a safety feature that automatically turns off when not in use to reduce incidents of overheating as well as save battery life.

The G Slim Herbal Vaporizer is a true example of modern vaping kit because this loose leaf vaporizer is designed to meet any user’s need for advanced technology and functionality. This vape pen was created to help ease the struggle of newbie users with its easy-to-use operational feature. Here, you just unscrew the mouthpiece to load your favorite herb materials then screw the mouthpiece in place and hold the button to start your draw. Overall, the exterior finish of the G Slim Herbal Vaporizer exhibits elegance and durability.


If you haven’t had a chance to hold this slim vape pen, here is a quick virtual tour on what to expect the moment you decide to give it a fair try for your next vaping session:

  • Battery

The battery is one of the economical features which I think all vaping enthusiasts cannot resist when choosing a vaping device the G Slim Herbal comes with a rechargeable lithium battery that can be easily carried and stored when travelling. The battery has 180mAh capacity which means you can enjoy at least 300 hits when fully charged. Charging cycle will take two to three hours.

One of the unique characteristics that the G Slim Herbal is proud to have is its economical battery. It is a rechargeable lithium battery that can be easily carried and transported anywhere you go, making it perfect for travelers who don’t want to miss their vaping sessions. The battery capacity is 180mAh, meaning you can get approximately 300 hits if fully charged. The required charging cycle is 2 to 3 hours.

  • 3 essential parts

The G Slim Herbal vape pen comes with 3 essential parts; the mouthpiece, heating chamber and rechargeable battery. Newbies will find this feature user-friendly because no need to worry of having to assemble many parts before using this vaping device as well as when cleaning.

  • Identical to any writing pen

Since it is completely identical to any writing pen, the G Slim Herbal can be used with discreet anywhere without drawing attention to any onlooker. Holding it can be extremely comfy because it’s very light unlike other vaporizers that are quite bulky.

  • Ceramic heating chamber

When you are on the lookout for an efficient vaping device, the G Slim Herbal won’t be a disappointment with its ceramic heating chamber. What’s good about having a ceramic made heating chamber? Expect only flavorful taste of your dry herb materials when vaping with a ceramic heating chamber. Aside from distinct taste of herbs, users can also enjoy quick heat up times because it has top performing conduction vaporization system.

  • Vapor production

Another awesome feature of the G Slim Herbal vaporizer making it a top choice among hit-chasers as it produces quality vapor even with its slim built. In fact, you can experience the same volume of vapor with this vaping device if you will compare it with other bigger portable herbal vape pen sold in the marketplace.


Since it takes the size of a writing pen, this herbal vaping device can be a perfect vaping buddy for outdoors, regardless you are off to a camping site or fishing with your friends. With its less hassle set-up feature and loading, you can have the privilege for a quick vaping session and slip in inside your pocket after usage.


For first timers who haven’t used a portable herb vaporizer, I recommend you fully charge the battery before taking your initial hit for better performance. You need to unscrew the chamber from the battery, then, screw the battery into the cordless USB charger. Once done, the battery light will turn red as indication of charging and eventually will turn green when the battery is fully charged. After charging cycle is completed, you can now screw the chamber to the battery, unscrew the mouthpiece to load your herbs and enjoy your initial hit. I suggest you grind your herb materials finely before loading to experience a flavorful vaping session. Operating it for the first time is also quick. You only need to do five clicks to turn the vape pen on and off.

Cleaning and maintenance

Cleaning the G Slim Herbal Vaporizer is also very easy with the use of the cleaning tool. Be sure to remove all unwanted residue from your herbs after every usage. This will make sure the coil is clean and efficient.

Overall impression

I’m a bit impressed on how this compact vaporizer performs during initial use. I didn’t have a hard time operating it for the first time with its easy operation feature of doing five consecutive clicks to turn it on and off. Loading this vaporizer is also less tedious as you just need to unscrew the mouthpiece and load the chamber until it reaches the 0.2 g load capacity. If you are a fan of flavorful herbs, the G Slim Herbal Vaporizer could be a perfect choice. While you still have plenty of time, read carefully this product review and be guided before making that final purchase from a vaporizer legitimate retailer.
