Using the G Pen Pro
The G Pen Pro is all about simplicity. Its design and operation are intended to be intuitive straight out of the box. However, some vape newbies might be a bit lost, so here's a basic rundown of its operation:
1. How to Operate Your G Pen Pro
The G Pen Pro is designed around a single button control scheme. Everything from turning on and off your device, to adjusting the temperature settings is done with a single button. To turn it on, click it five times in rapid succession, and do the same to turn it off. Changing temperatures is as simple as holding down the power button.
2. How to Get the Best Vapour Quality
The G Pen Pro is a compact convection vaporizer. This means that it vapes your herb by heating up the air around it and gradually baking the active ingredients out. When you're using a vape like this its important to pay attention to how you grind and pack your herb. You want a fine grind to expose the maximum amount of surface area and a loose pack to ensure that the air can flow through it.
3. How to Clean It
As with any vape, to clean the G Pen Pro, you simply use a cloth or q-tip to apply vaporizer cleaning solution or rubbing alcohol to any grime in the heating chamber. The Pro comes with a handy cleaning brush for any, particularly stubborn grime. When you're finished cleaning, ensure that you let the heating system go through a cycle to fully evaporate any left-over cleaning solution or alcohol.
What Makes the G Pen Pro Popular
The G Pen Pro is very popular with both beginners and those who want a simple vape for occasional use, here's why:
It's discreet and compact. Some people like a vape that grabs attention and some people want to enjoy their dry herb in peace. This vape is firmly for the latter. Its small size and understated aesthetics make it perfect for a low-key vape experience
It's simple and user friendly. Some vaporizers come with a broad temperature range, Bluetooth connectivity, and all manner of other features. This can be a bit much for some people. The G Pen Pro has a single button control scheme and straight forward design, ideal for those who value simplicity.
It has low draw resistance. Some casual and medicinal vape users find that many vapes have a very intense draw resistance. This can be uncomfortable. Thankfully, the Pro has a gentle draw resistance.
G Pen Pro Key Features
This vape covers the fundamentals thoroughly, but it has a few notable features that are worth spotlighting.
1. Small Size and Great Portability
The G Pen Pro is an extremely small vaporizer, standing at just 5" in length. This is small enough to fit in any pocket or bag for easy transport. This is no mean feat, vaporizers rely on fairly complex heating systems than can be hard to fit into a discreet package.
2. Solid and Durable
Though it is a small vaporizer the Pro is by no means fragile. It has an aluminium body that offers a great heft and durability that is more than able to stand up to the wear and tear of frequent use.
3. Rapid Heat-Up Times
The heat-up time of a portable vape is probably one of the most overlooked features. However, it is also one of the most important. Portable vapes are intended for quick, short sessions when you're on the go. Having a short heat-up time means you can get the most out of these sessions. The G Pen Pro has a super-fast 30-second heat-up time, so you can be sure you won't be left waiting around.
The G Pen Pro has a discreet and sleek design that is perfect for those who value subtlety in their devices. The design is comfortable to use, with a smooth finish without any bumps or lumps. Even the power button sits flush with the rest of the casing. Despite its compact size, it doesn't feel cheap thanks to its aluminium design.
5. Quick charge time.
No matter what, most portable vaporizers will have a charge time that is longer than its use time. Generally the shorter that time the better. The G Pen Pro has a use time that maxes out at around 60 minutes and a recharge time of around double that. This is a notably short charge time by vape standards!
6. Easy to fill chamber
This vaporizer is simple and convenient to fill. Simply remove the silicone mouthpiece to expose the chamber, tip your ground herb in, and replace the cap. Simple as that!
