G Pen Roam Vaporizer
The Original Portable E-Rig from G Pen (DISCONTINUED)
The G Pen Roam was a groundbreaking G Pen creation that redefined what a portable electric dab rig could be. As one of the first devices to integrate water filtration directly into its body, the Roam offered smooth, water-cooled vapor on the go — a true milestone in the evolution of concentrate vaporizers in Canada. Though discontinued, its design innovations continue to influence today’s best-selling portable E-Rigs.
Compact E-Rig with Built-In Water Filtration
The G Pen Roam introduced the world’s first fully enclosed hydro-tube system — a leakproof borosilicate glass water path built right into the vaporizer body. This allowed users to enjoy cool, filtered vapor without the need for external glass attachments or bulky rigs. It was the first truly travel-friendly dab rig that didn’t sacrifice performance for portability.
The integrated quartz tank paired with conduction heating ensured smooth vapor in seconds. With the Roam, Grenco Science successfully merged portability with functionality, offering the performance of a desktop E-Rig in a device that fits in your palm.
Precision Digital Temperature Control
The G Pen Roam featured digital temperature adjustment between 600°F and 800°F (315°C–425°C), giving users total control over their vapor profile. The LED screen displayed the current and target temperature, while haptic feedback signaled when it reached the desired heat.
Its innovative “Max Mode” pushed the Roam to full power, ideal for quick, high-temperature extractions or cleaning cycles. Few devices at the time offered such versatility, making the Roam one of the most advanced E-Rigs of its generation.
Quartz Tank for Pure Flavor
The Roam’s full quartz tank was engineered to preserve flavor and consistency, heating concentrates evenly across the surface. This setup eliminated the metallic taste found in older coil-based devices. Whether you preferred shatter, wax, or rosin, the Roam produced dense clouds with a surprisingly clean and terpene-rich profile.
Although newer devices like the G Pen Hyer now deliver even purer flavor with advanced quartz atomizers, the Roam’s design was an early leap forward for concentrate connoisseurs.
Durable Aluminum Alloy Build
Encased in a sturdy aluminum alloy shell, the G Pen Roam was built for real-world durability. It featured a magnetic housing that easily opened to access the quartz tank and glass hydro-tube for cleaning or refilling. The internal components were protected by a tight, sealed design that resisted leaks and kept the vapor path isolated from electronics.
The soft-touch finish felt comfortable in hand, while the compact, upright structure prevented accidental tipping. It was the first portable dab rig to successfully combine durability, design, and discreet operation.
Battery Life & Portability
A 1300mAh internal battery powered the G Pen Roam for approximately 20 sessions per charge. Recharging was simple through Micro-USB, and pass-through functionality allowed use while plugged in. For casual users, the battery provided more than enough power for a full day’s worth of dabbing sessions.
The Roam’s included hemp travel case made portability effortless. It stored the device and accessories securely, making it perfect for travel or outdoor use. Whether at home, in the car, or at a friend’s house, the Roam provided clean and consistent hits anywhere you went.
Smooth Vapor Performance
Vapor quality was where the G Pen Roam truly excelled. Its built-in hydro-tube effectively cooled the vapor before inhalation, producing smooth, water-filtered draws without harshness. The result was clean, flavorful hits that rivaled larger E-Rigs like the Puffco Peak, but in a more portable package.
For concentrate enthusiasts who value smoothness and consistency, the Roam delivered — especially when used in Auto Heat mode, which ramped the coil evenly to reduce temperature spikes.
Easy Cleaning & Maintenance
Despite its advanced features, the G Pen Roam was easy to maintain. The quartz tank, glass hydro-tube, and silicone airpath could be removed and soaked in isopropyl alcohol for thorough cleaning. A quick rinse and dry kept performance at its peak. Many users appreciated that Grenco prioritized practical design for long-term reliability.
How the Roam Changed Portable Dabbing
Before the Roam, dabbers relied on desktop rigs or simple pens. The Roam brought full-fledged, water-filtered dabbing into a handheld format. It inspired a new category of portable E-Rigs and influenced many modern designs that followed.
Its DNA lives on in the G Pen Hyer, which expands on its concept with higher power, improved quartz atomizers, and replaceable glass compatibility.
Looking for the Newest G Pen Models?
While the Roam has been retired, G Pen continues to lead in vaporizer innovation. The G Pen Hyer now carries its legacy forward with a 6000mAh battery, 5 temperature settings, and universal glass compatibility.
For wax and shatter fans who prefer a pen-style experience, the G Pen Micro+ is an excellent choice. For dry herb, check out the modern G Pen Dash+ — G Pen’s newest hybrid vaporizer for flower.
