Best Cheap Vape Pen G Pen Vaporizer Review

I have read a lot of reviews about the G Pen Vaporizer that said it was a ‘game changer’ for oil vaporing. What more could I do than try one? The G Pen is meant to make personal aromatherapy practice more convenient, discreet, simple and fun. It’s easy to use and has the ability to be taken anywhere. The G Pen is indeed a game changer. But it is important to note that it is only compatible with oils/concentrates and NOT herbs.

Construction and what’s in the box

The G Pen vaporizer moderately resembles, you guessed it, a pen. It very much looks like a calligraphy style pen, flattened out on one end by the mouthpiece.

It is about the size of a Sharpie marker. The G Pen can easily fit into your pocket and tag along, allowing you to vaporize anywhere. It is recommended to keep this little beauty in a case if you are traveling. The MSRP is $69.95 and comes with a G Tank, G Tool, Wall Charger, AC Adapter, and two Essential Oil Containers. It weighs about 2 pounds and measures 2x4x6 inches.

The G Pen utilizes a rechargeable lithium-ion G Pen battery. It was specifically designed to function with the Grenco science G Tank. Its mouthpiece and the tank itself (where oils are housed) are made of stainless steel. The G Tank transfers the perfect amount of power to vaporize essential oils at the ideal temperature before combustion.

 How it Works

The G Pen vaporizes essential oils. This trend is growing in popularity in the vaping community. If you let the G-Pen sit on its side too long it can spill, as is the case with nearly all oil-based vaporizers.  The oil is held in the separate replaceable tank. The G Pen comes from Grenco Science with a battery that is already charged. (Most electronic vaporizers need to be charged for hours before initial use.)

The tank system design is so user-friendly that anyone can remove the plastic storage cap, insert their product, and vaporize within minutes of opening their new G-Box. (“G-Box” is what Grenco Science appropriately calls the box that the G Pen and accessories come in.)


Grenco Science gives a 1-year warranty on select products.

This warranty is as follows: 30 days, no cost. If the product is found to be defective (electronic products only) there is a 1-year replacement program. This includes the G Pen’s lithium ion battery. Grenco Science asks that you keep your receipt. Please note, this warranty applies to the product only under normal usage and is subject to all product usage documentation by Grenco Science.

The G Pen vaporizer

Grenco Science takes all the most important variables into consideration such as temperature, average density, weight, and consistency, in order to build a unit that vaporizes, not combust your ingredients. This practice as you are probably aware is becoming more popular as it can eliminate the harmful toxins present in smoke while at the same time maximize the intended effect of your oil/ingredients through the smooth vapor.

The G Pen completely embodies this practice and provides its users with benefits through well thought out features. Don’t expect the G Pen’s battery to run out on you anytime soon. Each battery charge holds about more than 300 hits, far more than you would ever need in a day.

The G Pen has one operational button, making it extremely easy to use.The button allows the unit to heat up almost instantly. This feature makes the G Pen perfect for quick draws. The G Pen automatically shut off after 10 seconds to preserve battery life, promote safety, and keep the purity of your product. The G Pen hits as strongly as many of the much more expensive oil vaporizers.

What users are saying

Critics say that if you are looking to buy your first oil vaporizer, then should try out the G Pen. It’s  straightforward to operate, and easy to use. The single button operation can be utilized by anyone with virtually no instructions. It is logically designed, and users are able to load, use, and clean without much manual help or frustration.

Additionally, G Pen replacement parts are easy to find.  You can use it frequently and keep it working for a long time without breaking the bank. It is also recommended for those who are looking for a simple alternative to enjoy vaping without using herbs.

The battery is extremely reliable and holds its charge for a lot longer than other vaporizers. In fact, some reviewers have said they hadn’t experienced any battery problems months after purchase, even with heavy use. The looks and size of the G Pen give its users extreme portability and ability for discrete use. There is nothing more unassuming than a pen-like unit.

As stated previously, this unit can leak. Do not overfill the G Pen and leaking shouldn’t be a huge issue. Heated oils tend to expand and get more liquidy, so not filling it to the brim is highly recommended and will significantly reduce leaking.

“It is the best partner that I have with my aromatherapy regimen and will make you proud of owning one yourself,” said a current G Pen user.
