Grenco Science G Pen Roam


The G Pen Roam Vaporizer is a brand-new device launched just recently by vaporizer manufacturer Grenco Science. Known for its advanced and user-friendly devices, Grenco Science has been manufacturing products designed and engineered for on-the-go use. They stayed true to their nature when they developed the G Pen Roam Vaporizer. The G Pen Roam Vaporizer was a device intended to be a true portable eRig. Today’s industry is littered with devices that claim to be the personification of portable dabbing, but who are we kidding? eRigs are devices that can be considered portable but aren’t as convenient to carry as your portable device. They are outfitted with water attachments but it kind of hinders eRigs from achieving the same level of portability as dab pens, portable herbal vapes, and pod vaporizers. The G Pen Roam Vaporizer was built precisely to create an eRig that’s truly portable. The G Pen Roam Vaporizer is outfitted with a capable 1300mAh battery that allows you to take significant sessions in between charges. It charges via a USB charging cable which meant that you can recharge your G Pen Roam Vaporizer in various means. It also offers precision temperature control that lets you enjoy personalized sessions on-the-go. The G Pen Roam Vaporizer is also equipped with a slew of features that makes it one of the best-designed eRigs on the market today.

If you’ve been eyeing the G Pen Roam Vaporizer, here are a few things VapoCorner wants you to know so you can be sure that you’re investing in the right vaporizer. Here is our unbiased review of the latest and the newest eRig from Grenco Science.

A Portable eRig

A what? Yes, eRigs can be portable too. We’ve seen other manufacturers do this although with the use of an accessory. The G Pen Roam Vaporizer does this right out of the box. The secret lies in the G Pen Roam Vaporizer’s Hydro Tube. It’s an enclosed borosilicate glass tube that houses the water used to filter the vapors from the G Pen Roam Vaporizer. The Hydro Tube allows this portable eRig to prevent two of many consumer’s worst nightmares; leakage and breakage. The G Pen Roam Vaporizer Hydro Tube is a durable water attachment that allows you to enjoy water filtration and moisture-conditioned hits on-the-go – all without the need for any additional accessory. While other eRigs will have you buying more stuff to take your dabbing with you when you hit the streets, the G Pen Roam Vaporizer does that at no additional cost. What’s more, is that it makes for a durable glass component having been made from borosilicate glass.

The Hydro Tube is enclosed and housed in G Pen Roam Vaporizer’s aluminum body which not only helps dissipate heat but also ensures that the G Pen Roam Vaporizer is protected from other objects it might come into contact with. That said, you can easily out the G Pen Roam Vaporizer in your pocket, in your bag, or just carry it in your hands. This whole setup not only makes the G Pen Roam Vaporizer leak-proof but also a durable and a reliable device that delivers eRig-quality vapors whilst you’re on-the-go. It’s quite rare to see eRigs live up to the same level of portability let alone not let the water spill out of the glass attachment. For this reason alone, the G Pen Roam Vaporizer is worth investing in especially for consumers who like professional-quality dabs while they’re on their feet. At the time of writing, the G Pen Roam Vaporizer is the only true portable eRig we’ve tested so far.

If you like dabbing on a compact and portable device that offers the same features as your eRig, then the G Pen Roam Vaporizer is the right vaporizer for you.


Precision Temperature Settings

Even some of today’s most expensive eRigs can’t offer the same level of customization the G Pen Roam Vaporizer does. While it’s common for eRigs to have preset temperature profiles, the folks at Grenco Science knew they had more to offer and that they could do better. They outfitted the G Pen Roam Vaporizer with precision temperature control allowing consumers to easily alter the output of their vapors giving them the ability to calibrate the quality of the vapor production they get from the G Pen Roam Vaporizer. While using a preset temperature setting may be more convenient, having precision temperature capabilities at your disposal makes it so that you can get the most out of your dabs.

Having worked for years designing and developing dab pens and wax vaporizers in general, Grenco Science has understood the concept and the role that temperature plays in the vaporization of wax concentrates. Wax reacts to the slightest change in temperature and therefore active ingredients found in your extracts are released depending on how hot or how cool the heating element is. Warm temperature levels allow for the extraction of flavorful clouds of vapor while high temperature profiles activate the psychoactive ingredients in your wax. The same principle applies to how dense and how thick the vapors produced are. The lower the temperature settings, the thinner the vapor. The higher the temperature setting is, the denser the vapor production. To put it simply, having the ability to precisely point the temperature to where you need it to be works wonders especially when consuming wax concentrates.

This feature allows the G Pen Roam Vaporizer to shine and prove to be a better option especially for connoisseurs who have developed a particular liking or fondness of vapors produced and extracted in a specific manner. If you’re one to consume vapors using accurate and precise temperature control, then the G Pen Roam Vaporizer might just be the portable eRig you’re looking for.

Compact and Ergonomic

As we’ve briefly covered above, the G Pen Roam Vaporizer is a true portable eRig that allows you to carry it almost anywhere you go. It’s leak-proof and it holds well enough against daily carrying activity. It’s also compact and ergonomic. The overall dimension of the G Pen Roam Vaporizer allows you to hold it and operate it using only one hand. It’s designed in such a way that it can easily be used without the need to use two hands unlike other eRigs on the market today. Its profile tells you immediately that it’s no regular eRig.

Unlike other devices in the same platform, the G Pen Roam Vaporizer measures only at around 6 inches with a thickness of roughly an inch. This portable eRig feels right at home in your hands and unlike the towering 7-inch eRigs that feel more like they belong atop your table than in the palm of your hands, the G Pen Roam Vaporizer provides its users with the means to comfortably hold the unit with ease.

However, because of its small and compact size, the G Pen Roam Vaporizer suffers from having only a small battery. It’s outfitted with a 1300mAh battery that can provide decent hits in between charges, approximately 15 sessions in a single charge which isn’t bad especially when you’re dabbing on your own but may fall short when you use the G Pen Roam Vaporizer in group sessions. Having said that, before deciding to commit to buying and investing in the G Pen Roam Vaporizer, you should be aware that the battery life is fairly limited compared to the usual 3000mAh battery found on most of today’s eRigs. Nevertheless, the battery can still be used while plugged in the power outlet. Its pass-through charging capabilities can help make up for the lack of battery capacity but be sure to keep yourself within range or close proximity of a wall outlet when taking on group sessions.

It’s a device we can recommend for beginners and for those who usually dab by themselves.

A True Extract Vaporizer

The G Pen Roam Vaporizer was designed and engineered for the vaporization of wax concentrates only and does a good job thanks to its components that are dedicated to the sole purpose of vaping wax. To begin with, the G Pen Roam Vaporizer uses a quartz tank that heats your extracts via conduction heating. Quartz has been one of the most-used heating elements in vaping wax concentrates because of its unique properties. For one, quartz is a good catalyst for heat and can heat up wax concentrates in seconds. Because it easily transfers heat from the coil to the materials in the tank, it can provide you with results in seconds. Its quartz tank also allows you to heat the wax concentrates cleanly for that impeccable vaporization of your wax concentrates.

However, the G Pen Roam Vaporizer is not a dual-purpose vaporizer and as we’ve mentioned above is able to vaporize only wax concentrates and other forms of extracts. It is not compatible with dry herbs. This means that you won’t have the same benefit as other eRigs that allow the vaporization of both herbs and wax concentrates which makes them basically two vaporizers for the price of one. Nevertheless, the G Pen Roam Vaporizer is a solid and a reliable vaporizer for those who want an eRig they can use while they’re on-the-go.
