The G Pen Roam is a portable e-rig concentrate vaporizer from Grenco Science. It is a sturdy handheld concentrate vaporizer with a body somewhat reminiscent of the Mighty+. Besides the ability to dab with only one hand, what sticks out about the G Pen Roam is the smooth dabs offered by the internal Glass Hydro Tube and the option to use it like a dab rig or an on demand vape
The G Pen Roam is made of an aluminum alloy shell and is sturdy as it gets and it offers a removable Quartz Tank providing the ability to heat fast to very high temperatures without worrying about burning out. The Roam’s internal hydrotube also gives you smooth vapor even at the highest temperatures
The G Pen Roam can work like a dab rig with 30 second sessions in automatic mode , or you can take small puffs from it with the push of the home button in manual mode. Which ever one you choose the G Pen Roam functions much like any other concentrate vaporizer where you fill the chamber and let her rip
Given the option to use the G Pen Roam in session or automatic mode and the G Pen being sturdy and portable , you can choose if you want session with your friends like you would a standard dab rig or just hit it on the go between study breaks like you would a typical vape pen

It's all in the packaging
Normally we like to skip the packaging and get right into the vaporizer, but the G Pen Roam is one of those vaporizers that has great packaging which can double as a carrying case. The last time we saw packaging which could double as a nifty carrying case for the dab rig was with the Puffco Peak.
And while the Puffco Peak’s packaging may be functional, the Roam’s case is functional and stylish. The Roam’s packaging is made out of hemp with holders for concentrate jars or wax wallets and pockets for your dab tools. So it is not only designed to carry the Roam, it is something you would want to carry it around in.
The packaging is forthtelling of the quality construction of the G Pen Roam. Grenco Science is an established name in the vaporizer space, but their herb vaporizers are not known for being “high end”. The G Pen Roam is an exception, everything about it feels top tier.
On the Go or at home
One of the best facets of the G Pen roam is the ability to take it with you in the nifty little case provided or use it at home like you would a standard dab rig. It offers duality where most concentrate vaporizers are going to be pens for out and about or desktop vaporizers for at home use.
Body The G Pen Roam is made of an aluminum alloy shell and is sturdy as it gets
The Quartz Tank provides the ability to heat fast to very high temperatures. Since the atomizer is removable it would be nice to see Grenco make a ceramic atomizer for lower temperatures for those looking for flavor. The quartz tank does offer plenty of room as with dabs you do not need alot.
Water filtered dabs
The Hydrotube is the G Pen Roam’s pièce de résistance . Unlike other concentrate vaporizers where you add the water before you fire it up, the G Pen Roam has an internal hydrotube which runs directly into the mouthpiece, cooling the vapor before you inhale.
Battery Life & sessions
The Battery is a 1,300 mAh lithium-ion battery. Since the battery is built into the vaporizer where the LED display and heating element sit, you cannot replace it with 3rd party batteries. The battery is takes up a huge portion of the vaporizer.
I have not heard too many people complain about the battery life on the G Pen roam, but it does offer pass through charging which is always a great option to have in any vaporizer, as nothing is a bigger bummer than going for a session only to find your vaporizer needs to charge up. The G Pen Roam at least lets you plug it in and vape away.
You can get around 15 – 20 30 second sessions with your G Pen Roam , depending on your heat level. More if you are operating in Manual mode.
In Automatic mode you press the power button two times after selecting your temperature. The Roam will vibrate when it reaches temperature and again 30 seconds later when the heat disengages. You can also disengage the heat in automatic mode by pressing the power button two times.
Manual mode is much like using your standard coil vape pen. You hold the power button down, draw, let go, repeat.
While the high temperatures go down smooth with the water filtration, the taste and flavor which you get from other high end concentrate vaporizers is lacking. The G Pen Roam is better suited to get you elevated and get you a voluminous amount of smooth vapor with the press of a button, but if you want flavor and Volume I would go for the Puffco Peak.

I’d like to say “They Nailed It! :” However, Grenco did not knock the leather off the ball with this design.
The unit needs daily maintenance, which isn’t terribly hard to perform: However, concentrate does leak through the quartz tank chamber and gets on everything... inside the Roam. You don’t want to have to clean this during or right after a session, so you’ll have to remember the to service it afterwards, when it’s cooled down, because the internal glass bubbler is really expensive to replace if you break it accidentally. Furthermore, if you don’t service it as Grenco recommends, your medicine/concentrate will taste burnt and unpleasant: I really do need to clean the unit after each session – especially if its a battery draining one, even though I’m a light sipper.
The other thing I don’t care for is that the battery is not replaceable/removable, to keep a session going: Even when the unit is plugged in, the user has to wait till at least one or two bars, before the Roam actually will “Passthrough” enough current to power the battery. In other words, if you don’t have any bars, while your Roam is plugged into your USB port, you’re not going to be able to puff on this device till you do. Also, when the Roam is on the USB charger / or off the charger with a full battery, it is possible to overheat the unit and get a flashing warning on the indicator led panel; and the device will power itself off during longer sessions of just a few minutes at higher temp settings.
With all that said, the Roam is a fun and effective vaporizer for concentrates – if not a useful hand warmer. It seems ingeniously designed – both aesthetically and ergonomically, but doesn’t seem economical imho, as a replacement battery retails for more than $125 USD as of this posting, and the glass bubbler tube I’ve seen selling for more than $35.
When the Roam is clean and has a good charge, You’ll forget about a lot of the before mentioned, and really enjoy a full flavor profile running your unit at lower temps, rather than torching the flavor out of your concentrates at greater than 700F, because operating your Roam at those high temps will run your battery indictor down in one session. Grenco, states the Roam can delivery approximately 15 draws on a full charge, and it does; but then you’ll have to charge the battery again to operate the Roam in “Max” mode to clean the Roam’s quartz tank, which could leave you with less time to vape on the remaining charge.
Overall, the Roam seems a great device if you’re a light puffer type or especially if you’re the clumsy type: Let’s say after or during a session you drop your Roam accidentally, you’re not going to have to worry about stepping on glass or your pets doing the same, as the Roam is fully self contained- to a point. The G Pen Roam is a useful tool for concentrates than some other devices I’ve owned over the past decade, and I give credit to Grenco for their forward thinking, innovative design and superlative and compassionate customer care support team. Grenco offers a slightly longer warranty if you register the device, so I recommend doing so, as some reviewers have mentioned shorter battery life and leaking concentrates gumming up the power on/off button – which could have to do with not cleaning the Roam as instructed. Grenco says- to paraphrase – with the Roam, a little is a lot – referring to the amount of concentrate in the chamber- I’m guessing this to keep the concentrate from oozing out of the chamber and into the internal controls.
I’m undecided whether to return the Roam for the before mentioned reasons. I strongly considered the dr. dabber switch first, and since the Roam seems to deliver on a lot of what I was looking for in a portable concentrate vaporizer. I think overall if my G Pen Roam doesn’t fail me during the warranty period it’ll be a keeper, as I found the manufacturer to be responsible and compassionate as well.
Oh, and forgot to mention the travel case: It’s also nicely designed with Mother Earth in Mind; as well being durable and functional.
Thank You Grenco for marketing an intuitive, thoughtful and useful tool like the G Pen Roam for vaporizing concentrates; and for assembling a caring and professional team of individuals.
Awful garbage, very clever design and well constructed but the atomizer design is so bad it ruins everything. The bucket leaks concentrate directly onto the heating wire underneath where it burns and now every hit will taste burnt.
