G Pen Pro

Continuing in the long line of superior vaporizer engineering, the G Pen Pro from Grenco Science raises the bar once again by utilizing a huge ceramic oven that heats instantly in a sleek, refined, yet perfectly ergonomic form factor. Despite its small size, the G Pen Pro has a large battery that will keep you vaping session after session. The generous ceramic oven imparts no flavors to your material, you only taste exactly what you load. The three different heat settings allow to you achieve your personal level of vapor perfection, and as your strains change, so do your temperature needs. The G Pen Pro has you covered. Included is a key chain poker, cleaning brush and USB charging cable. The GPen Pro allows for pass-through charging while in use.

Ergonomic Design

How it Works

Be sure to fully charge the G Pen Pro (minimum of 3 hours). Grind your material to medium-fine grind, and fill the oven to the top of the white. Replace the mouthpiece, and turn the GPen Pro on. Set your temperature level, and the G Pen Pro will be ready to go in 30 seconds.


Use a small cleaning brush between every time you empty the G Pen Pro. This will help remove any residual debris from the chamber. For a deeper clean, cotton swabs and isopropyl alcohol can be used. The chamber should be fully dried before subsequent use.
