The G-Pen is a wax pen from legendary vape company Grenco Science. The entire unit consists of a dual-quartz rod atomizer, wrapped in Kanthal coils, and a battery, which has a single power button.
The G-Pen concentrates pen is very compact and lightweight. The three parts that make-up the device are the battery, atomizer, and mouthpiece.
The battery has a rubberized exterior, soft-to-the-touch, and has a single, polished, metal firing button in its front. There are two LED lights, one behind the power button, and the other at the base, both of which will flash whenever the battery is turned on.

The atomizer section has high-quality materials throughout, like the stainless steel, and borosilicate-glass heating chamber inside. The mouthpiece is black plastic, but given that the rest of the device is well-built, the mouthpiece’s construction can be overlooked.
The atomizer has the same rubberized exterior as the battery. The mouthpiece section unscrews from the heating chamber, and underneath it, there is a stainless-steel, wire-mesh filter to purify the vapor coming up out of the chamber.
Working the G-Pen Wax Vaporizer
One advantage of this unit is its straightforward usability. The atomizer has proprietary threaded, unique to only Grenco Science batteries, so it cannot be used with 510 or 810 threaded cells.
There is a separate dry herb atomizer that features the same threading so it can be used with this battery. The dual-quartz rods are a little further down than similar chambers, which can make loading sticky waxes and dabs a little tricky.
If loading does prove difficult, try heating the dab tool a little to make sure the material melts off instead of sticking to it. The other option is to slightly freeze the wax, hardening it, so it does not stick while the loading the chamber.
Once the material has been successfully loaded, screw the mouthpiece back on, and click the power button five times. To take a hit, press and hold the power button, and inhale.
Taking a Vape with the G-Pen
The vapor production on the G-Pen is excellent, flavorful, smooth and not harsh at all. The clouds are not so big, but for a small, discreet vape pen, gigantic plumes of vapor are not to be expected.
On a fully charged battery and less than a gram of material, 5-10 hits can be expected. The battery life is excellent as well, with the cell going out about an hour with heavy use.
The G-Pen Wax Vaporizer vs. the Mig Vapor WASP vs. the KandyPens Prism
The Mig Vapor WASP
The WASP has an atomizer that contains carborundum rods wrapped in stainless steel coils that make them longer-lasting. It also features a Pyrex glass mouthpiece, and a stylish green PC tube to ensure a clean and pure vapor path. The vapor production of the WASP’s 900 mAh battery combined with the 1.0ohm resistance of the coil is also full and bountiful.
The KandyPens Prism
The KandyPens Prism is rare for KandyPens as it is a serious, wickless, dual-quartz atomizer with four preset temperatures. The Prism has a minimalist, stream-lined, all stainless-steel exterior and one-button controls.

The G-Pen Wax Vaporizer: The Last Word
The G-Pen is a good buy, considering the quality of materials and the fact that the battery can be used with other Grenco atomizers for dry herbs or liquids.
The vapor production may not satisfy all, but for vapers who want to remain discreet while they are vaping in public, the G-Pen gives off satisfying hits without clouding the immediate surrounding.
