The G Pen Roam is a portable vaporizer engineered specifically for wax and solid concentrates. It integrates a spill-proof, self-contained water filtration system within its durable aluminum alloy shell, designed to cool and purify vapor on the go. This device caters to users seeking the benefits of water filtration without the bulk of a traditional rig. With a full quartz tank and digital temperature control, it aims to deliver flavor and performance in a compact, travel-friendly format. The entire vapor path can be disassembled for straightforward maintenance, ensuring a clean experience with each use.

Integrated Water Filtration

The Roam features a borosilicate glass hydrotube that is enclosed within the device’s main body for protection. This self-contained water filtration system is designed to be spill-proof, allowing for smooth, water-cooled vapor while maintaining portability. The hydrotube can be filled with water to cool down and purify each draw, offering an experience often associated with larger, stationary dab rigs but in a format suitable for travel and discreet use.

Precise Temperature Control

This vaporizer offers a digital temperature control system with a range from 400°F to 800°F (204°C to 427°C). Users can adjust the temperature in 25-degree increments to suit their specific concentrate and preference. The selected temperature is shown on a clear LED display, and the device provides haptic feedback, vibrating to signal when it has reached the desired temperature and is ready for use.

Quartz Tank and Pass-Through Charging

At the core of the Roam is a full quartz tank, a material chosen for its ability to heat concentrates evenly without affecting their flavor profile. The device is powered by a 1300mAh lithium-ion battery. It also supports pass-through charging technology via a micro USB port, which means the vaporizer can be used while it is connected to a power source, minimizing downtime between sessions.
