Grenco Science G Pen Roam

G Pen Roam Vaporizer – Smooth Concentrate Sessions Anywhere

The G Pen Roam is a portable concentrate vaporizer designed for water-filtered draws without the bulk of a glass rig. Built with an ergonomic shell that houses a quartz heating tank and an all-glass hydro-tube, the Roam delivers cool, flavorful vapor at the press of a button. Compact, spill-proof, and easy to travel with, it’s a serious upgrade for concentrate lovers who want performance and portability in one.

Powerful Battery for All-Day Use

The Roam runs on a 1300mAh lithium-ion battery that heats up fast, lasts for about 20 sessions per charge, and can even be used while charging. A full recharge takes around 90 minutes, and the battery is swappable so you can keep the sessions rolling without waiting. Automatic 30-second heat duration helps conserve battery life while still giving you plenty of time for a strong pull.

On-the-Go Water Filtration

At the core of the Roam’s design is a glass hydro-tube filtration system built right into the body. Acting as both the vapor path and cooling system, the hydro-tube sits directly under the mouthpiece for pure, fresh hits without extra airspace. This makes every draw smooth, flavorful, and easy on the throat—perfect for quick rips or extended sessions.

Quartz Tank = Pure Flavor

Unlike titanium or ceramic, the Roam’s full quartz tank preserves terpenes while still pushing dense clouds. Paired with the strong battery, quartz heats up quickly and keeps flavors crisp even at high temps. With a wide temperature range of 600°F to 800°F, you can dial in low-temp flavor sessions or crank it up for thick, milky vapor.

Customizable Controls + Max Mode

A simple three-button setup makes the Roam easy to navigate. The LED display gives you real-time temperature feedback, and you can adjust temps in 25°F increments for precision. When it’s time to finish up, switch to Max Mode to clear out leftover concentrate and keep your chamber fresh.
