The G-Pen from Grenco Science is a gorgeous vaporizer for dry herb. This is a perfect first vaporizer. If you know someone who is trying to switch from smoking to vaping, this is the kind of device to give the person as a gift. Although this is a basic dry herb vaporizer, it will give you ultra-smooth hits. This is not a cloud chasing, but it will give you great flavor. The G-Pen does not have any complex controls. It has only one button which you can use to turn it on/off and also activate the heating elements. What’s more, this vaporizer is relatively affordable.

What is included in the package:

  • G-Pen herbal vaporizer
  • Rechargeable battery
  • Herbal tank
  • USB charger
  • AC wall adapter
  • G Card
  • 3 Cleaning tips
  • Cleaning brush
  • 2 Glass sleeves

The Grenco G-Pen has a sleek design. It is available in black color. The outer shell of the device is made of stainless steel, and it has a plastic mouthpiece. The tank/heating chamber of the device is made of glass. Every aspect of this device is well made. You will not struggle to dismantle it and assemble it back together.

Before you use this vaporizer for the first time, it is important to charge it for 2 to 3 hours. The G-Pen is made with a 900 mAh battery which can last you for a few hours of vaping or for about ten sessions. It takes about 2 hours for the device to recharge when the battery is empty. To charge this Grenco vaporizer, you need to connect the battery to the USB charger. You can choose to plug the USB into a laptop or fix the AC adapter and charge it directly from a power outlet.

The tank of the G-Pen vape pen is located directly under the mouthpiece. To access the tank section, you need to remove the stainless steel sleeve on top of it. The tank is made of glass. The chamber has a ceramic base with a coil sitting on top of it. When you press the power button, you can see the coil glow red hot. The tank of the G-Pen is not huge. You can only put in a few pinches of herb before it is full. Do not try to stuff the chamber with a lot of herb at once. You can get up to 10 draws before you need to clean the chamber. If you find that the airflow is a little restricted, try stirring the herb in your tank. This device can reach up to 215 degrees Celsius.

To turn the device on, you need to press the power button five times in quick succession. When the device comes, a blue light will flash at its base section as well as around the power button. The device is designed to automatically shut off after only 11 seconds. You simply need to press the power button to turn it on. You need to press the power button for about 2 to three seconds before each puff and continue to hold it while you draw.

Overall, the G-Pen herbal vaporizer is a solid device. There is only one problem with it; it can burn your herb. This is not a major issue, but you can reduce it by allowing some seconds pass between each puff. The combustion of herb in this device happens because there is nothing separating the heated coil from your vaping material. The tank chamber of the G-Pen is replaceable. You can use one for up to 8 weeks before you will need to replace it. The fact that this device combusts herb makes it unsuitable for vaping in public because it will easily give you away.

Grenco Science has another version of the G-Pen that is a wax vaporizer. There is also a Snoop Dogg G-Pen that is very similar to the G-Pen herbal vaporizer.

You can get the G-Pen herbal vape pen and other devices in the G-Pen series from just about any top vape store. This device usually costs about $70, but you can get it on Ejuice Pack for only $60.16.
