The G Pen Roam by Grenco Science is an ultra-portable e-rig that uses water filtration and precise temperature controls to deliver smooth potent hits. Concentrates are vaporized within the quartz tank and then cooled through the spill-proof borosilicate glass hydro-tube.

The Roam is powered by a powerful 1300mAh lithium-ion battery with variable temperature settings ranging from 600F to 800F with 25F intervals. A full charge takes approximately 90 minutes and last about 20 sessions. Passthrough technology allows the use of this e-rig while charging.

Built within a aluminum alloy casing for durability and featuring a silicone hand grip for comfortability. Cleaning the Roam is as easy as using it as the parts can be individually removed and cleaned of residue. The Roam excels at being a discreet stylish concentrate vaporizer capable of delivering traditionally water filtered hits anytime, anywhere.
