Grenco Science G Pen Roam Vaporizer

The G Pen Roam is a portable e-rig like no other. The Team at Grenco Science has provided a range of portable vaporizers and e-rigs over recent years. We think the Roam may be the best yet!

The G Pen Roam is one of the most portable concentrate rigs on the market today. Something unique to the Roam: a water bubbler situated in the interior of the unit. The bubbler helps to cool the vapor produced by the Roam and is designed expertly forming a perfectly spill-proof filtration tube.

The design of the G Pen Roam couldn’t be more user-friendly if it tried, and also makes it super durable, too. It’ll fit easily into the palm of your hand, and any pocket too. The spill-proof design of the hydro tube means it can be stored any-way-up and still be perfectly usable whenever you need it.

If you’re passionate about concentrates and need an e-rig to support your day-to-day on-the-go sessions, the G Pen Roam is made for you! 

Cookies x G Pen Roam

When two giants collaborate, there’s little reason to expect anything other than the best. This is certainly the case with Cookies and Grenco Science. 

What they’ve created is the G Pen Roam we all know and love, but with a twist. In size and function, it’s identical to the original Roam. Where it differs is in its design. The Cookies x G Pen Roam is designed in Cookies’ signature blue color with white buttons, reminiscent of all Cookies branding and products. 

The Cookies x G Pen Roam is any concentrate-lovers dream. It’s portable and stylish yet flawlessly functional. This exclusive collaboration is a must-have for any loyal Cookies fans.

How To Use The G Pen Roam?

So let’s take a look at how you can get started with the Roam. These are just some of our tips to get you started, and how we think you can get the most from this portable powerhouse. 

1. How To Operate The G Pen Roam?

So to start, just like any electronic device, you’ll need to charge it fully. This process takes approximately 90 minutes. Now you’ll have to take the G Pen Roam apart by sliding the hydro-tube out by removing the mouthpiece. Fill the tube with water to the line which is usefully drawn to guide you.

It’s now time to load that atomizer with your concentrate using the dab tool. Close the cap and press the main button 5 times to turn on the Roam. The +/- buttons are there for you to navigate through the temperature options. The temperature will rise/lower in 25-degree increments. From here, press the button a further two times to begin heating. When it’s ready to go, it’ll vibrate and the LED display will show a thumbs up. 

2. How To Get Best Vapor Quality?

What determines the best vapor quality depends largely on your preference, but there are some tips. Using the lower temperature settings will optimize the G Pen Roam to emphasize the flavor of your concentrate. The higher temperatures will produce luscious thick clouds of vapor. 

3. How To Clean It?

The benefits of keeping your Roam clean are self-explanatory. After all, you won’t want any burnt tastes from leftover residue in the atomizer. That’s a sure way to ruin your experience and decrease vapor quality.

The G Pen Roam features a self-cleaning mode to make your life a lot easier. To activate it, increase the temperature to the highest setting (800 Fahrenheit), and press the + button one more time. This initiates a thorough deep clean at soaring temperatures to completely clear the coil, ready for your next session.
If there’s any leftover residue you can use the cotton swabs provided dipped in some isopropyl alcohol. 

Quality

Something we’ve come to expect from all products by Grenco Science is quality. The best quality on the market. The G Pen Roam is no exception to this. The outer body of the unit is crafted using aluminum. This forms a strong, durable shell around the electrical components and glass bubbler. 

The different parts of the Roam are easily separably. The battery, mouthpiece, and glass bubbler all slide apart from one another, and are held together firmly by magnets when assembled.

The design is not all that’s high-quality in the G Pen Roam. Thanks to the borosilicate water-bubbler the vapor produced are flavorful, smooth, and will keep you refilling that chamber! 

Temperature Settings

The G Pen Roam boasts its ability to give users 100% control over the temperature they’re dabbing at. The temperature range of the Roam is 400°F - 800°F and the directional buttons allow you to navigate through these temperatures.

There is a manual mode, in which holding the power button will fire heat at your chamber until your session is done. Meanwhile, the automatic mode allows you to choose your temperature while the device heats up to it automatically. 

Battery & Power

The battery of the G Pen Roam is a 1300mAh lithium-ion battery which is chargeable through the provided micro USB. It takes approximately 90 minutes, which provides roughly 20 sessions of use. This will depend on the temperatures you’re choosing, though. The higher temperatures, as you’d expect, tear through the battery faster than lower presets.

A great feature of the Roam is its auto shut-off feature which turns the device off after a period of no use. This saves you hours of painful waiting and charge time, so you have more time to enjoy your concentrate. 

Portability

The G Pen Roam is a durable, perfectly-sized concentrate vaporizer perfect for supporting your on-the-go sessions. It comes with a stylish hemp travel case to hold your Roam device, your concentrates, and the charger. The G Pen Roam can effortlessly follow you wherever you go. 

Who Is The G Pen Roam For?

The Roam is all any concentrate connoisseur could ask for. It manages to produce smooth and dense vapor like a desktop e-rig while being so conveniently portable. It’s stylish, discrete, fit’s perfectly in your hand and a perfect way for the desktop experience on-the-go. 

Who Is The G Pen Roam Not For?

The G Pen Roam is an e-rig created for concentrates. This is fantastic news for many, but what about the dry herb lovers out there?
Well, if you only consume dry herbs, the Roam is probably not the best choice for you. 

Compare With Other Products

Dr. Dabber Switch

The Dr. Dabber Switch is a perfect alternative to the Roam. Where it predominantly differs is in its size and material compatibility. The Switch is compatible with both concentrates and dry herbs with both Oil Mode and Leaf Mode. 

It’s larger than the Roam, so can be deemed as more of a desktop option although it is possible to take with you if you have a bag to carry it in. 

Puffco Peak Pro

The Puffco Peak Pro has become a classic in the world of electronic dab rigs. From its design to its function, it’s one of the best. Just like the Roam, it’s an e-rig designed for use with concentrates, so if you’re set on extracts it’s a great choice.

A nice aspect of its design is it allows you to view the water bubbler fill with vapor as your concentrate heats. If this is something important to you, it may be worth looking at the Peak Pro.

G Pen Roam FAQ

Is the G Pen Roam Safe To Use? 

The G Pen Roam is an incredibly well-built e-rig that is safe to use. While the idea of the water bubbler being situated inside the unit, close to the electronic components sounds worrying. The bubbler has an anti-spill design, so no matter what the water will not leak out.

You’ll need to be careful you don’t crack the bubbler while handling it, though. It is glass after all. While the Roam is fully assembled there’s no need for worry, however. 

What Can You Use With The G Pen Roam? 

The G Pen Roam is a portable e-rig designed specifically for use with dry herbs. As far as on-the-go dabbing goes, it doesn’t get much better than this. 

Can You Adjust The Temperature on The G Pen Roam?

The temperature of the G Pen is fully adjustable, and the user has full control at all times. The temperature increases and decreases in 25-degree increments, and can be done using the +/- buttons.

Is The G Pen Roam Portable? 

The Roam is one of the best portable e-rigs around. It compares to the Puffco Peak Pro in a lot of ways, an e-rig that took the market by storm upon release, but is arguable more portable. The glass bubbler inside means sessions on-the-go less risky and more convenient. It’s got a great battery life and an auto shut-off feature that’ll support all your needs.
