Product Description

G Pen Pro Vaporizer Features

The original G Pen Pro Herbal Vaporizer features convection heating and an all-ceramic heating chamber with very low conductivity for pure and flavorful vapor that is free of toxins and irritants. The G Pen Pro’s new larger herb chamber will hold roughly 0.5 grams of dry herb, much more than most portable vapes on the market. Built to emphasize flavorful vapor, this top-of-the-line portable vape comes with a rubberized mouthpiece with improved airflow for smooth and cool draws.

The G Pen Pro is designed for quick draws while on the move, perfect for those with a busy lifestyle. Uniquely compact and elegant, the G Pen Pro’s advanced heating system offers three pre-set temperature settings (375° F, 400° F, 428° F), giving dry herb consumers say over cloud production. Temperature settings can be easily toggled by holding down the device’s single button. With its powerful battery, the pocket-friendly G Pen Pro heats up in 30 seconds or less, perfect for quick and discreet sessions. The G Pen Pro is made of high-quality materials and features a durable aluminum exterior, allowing it to seamlessly handle on-the-go use

The G Pen Pro Vaporizer features single-button functionality, making it easy to use for both beginners and enthusiasts. An impressive LED light display clearly indicates power and temperature settings, as well as battery status. An automatic shut-off feature kicks in after 5 minutes of non-use to preserve the G Pen Pro's battery.

Every order comes with the G Pen Pro Vaporizer, a G Card Grinder, a Mouthpiece, a G Pen Tool, a Cleaning Brush, a USB Charger Cable, and an Instruction Manual. To recharge the battery, simply plug the USB charger cable into the bottom of the G Pen Pro and the USB charging device into any USB port. The LED lights on the device’s display screen indicate how much charge is remaining, and will glow green when fully loaded.

Vaporizers like the G Pen Pro appeal to dry herb enthusiasts seeking a throat- and lung-friendly inhalation method. The G Pen Pro utilizes convection heating to avoid combustion, safely heating up botanical herbs to their boiling points for clean and pure vapor free of toxins and dangerous byproducts. For health-conscious botanical consumers, the G Pen Pro and vaporizers like it have quickly become a popular choice.
