The G Pro is a portable, easy-to-use vaporizer that’s designed for dry herbs.

By now, you’ve probably seen your fair share of portable vapes, and you’re probably wondering what makes this one so special. While the G Pro isn’t perfect, it’s miles ahead most of its competitors. In this G Pro vaporizer review, we’ll take a look at how this vaporizer works and what it has to offer.

G Pro Vaporizer

What is the G Pro Vaporizer?

Made by Grenco Science, the G Pro is a vaporizer pen that uses convection to vaporize your dry herbs. The results? Pure vapor and a rich taste.

Durable, easy-to-use and small enough to take with you anywhere, the G Pro is a smart choice for anyone who’s newer to vaping. Because of its low price tag, it’s also a great choice for anyone on a budget.

Performance and Features

There’s a reason why the G Pro is such a popular vaporizer pen. For starters, it’s one of the most affordable models you can buy. If you’re just getting started and you don’t to spend a lot on a portable vaporizer, the G Pro is a smart choice.

Aside from its price point, this vaporizer is also easy to use and offers great vapor quality. That’s partly due to the method of heating the herbs. I do want to mention, however, that you can only use dry herbs in the G Pro. If you’re looking for a vaporizer that’s compatible with liquids or waxes, this isn’t the device for you. You may want to try the Micro G Pen instead.

Let’s take a closer look at this vaporizer’s features, so you can get a better idea of what it has to offer:

Variable Temperature Settings

The G Pro allows you to adjust the temperature based on your personal preference and/or the material you’re vaporizing. While you won’t be able to set a precise temperature, you do have the option of choosing between three settings:

  • Red: 320F/120C
  • Green: 380F/193C
  • Blue: 420F/215C

The temperature color is displayed right under the power button, so you can’t miss it. All you have to do is press and hold the power button to cycle through the different temperature settings.

Heat up time is quick, too. In less than a minute, you’ll be ready to vape.


The G Pro was built to last. Internally, the vaporizer’s chamber is constructed with a heavy-duty stainless steel. The great thing about stainless steel is that it release’s the herbs botanicals without producing any harmful side effects.

While not quite as efficient as ceramic or other materials, the G Pro produces a clean-tasting vapor with an unadulterated flavor.

Generous Filling Chamber

With the G Pro, you can pack up to 500mg of material into the filling chamber. With a larger filling chamber, you can enjoy longer sessions. In just one full packing, it’s possible to get between 10 and 15 draws.

As far as performance goes, the G Pro is really easy to use, and the vapor quality is above average. The lowest temperature setting will give you the best flavor, but the least amount of vapor. On higher temperature settings, the vapor increases, but the taste starts to diminish after a few draws.

G Pro vs Other Grenco Science Vaporizers

You know that the G Pro is a popular vaporizer, but how does it compare to other vaporizers from Grenco Science?

The G Pen

The G Pen is another one of Grenco Science’s popular vaporizers. It’s similar to the G Pro, but it doesn’t offer the same sleek design or temperature controls. This is a true vaporizer pen, and it’s discreet, but it doesn’t offer the same level of control.

You’ll also find the Snoop Dogg G Vape in the G Pen collection. The only difference between the Snoop Dogg and original G Pen is the design. The Snoop Dogg edition features a detailed map of Long Beach on the exterior of the pen as well as an engraving of Snoop’s signature.

Like the G Pro, the G Pen is a great entry-level vaporizer, and it comes at an affordable price. But for just a little bit more, the G Pro offers temperature control and a better overall design.

Micro G Pen

If stealth is your top priority, than the Micro G Pen may be the best option for you.

This particular vaporizer is not compatible with dry herbs. You can only use essential oils with this one. But it’s incredibly small and compact, which makes it a great choice for people who are on the go.

Like the G Pen, the Micro G Pen does not offer temperature control. Unless you’re only planning on using essential oils, the G Pro is the better option – hands down.

How to Use the G Pro

The G Pro is a great choice when vaping for beginners. This is partly because it’s so easy to use and maintain.

Here’s what’s included with the G Pro:

  • 1 G Pro
  • 1 mouthpiece
  • 1 removable filter
  • 1 cleaning brush
  • 5 filter screens
  • 3 mouthpiece sleeves
  • 2 extended mouthpiece sleeves
  • 1 wired USB charger
  • 1 G Card

When you first receive the G Pro, you’ll need to make sure that it’s fully charged before you start using it. Just connect the USB charger to any compatible USB port, and you’re good to go. The power button light will turn red, and once fully charged, will change to green. It takes between one and three hours for the device to fully charge.


Loading the G Pro is simple and easy.

  1. Remove the mouthpiece. To do this, you’ll need to apply just a little bit of pressure upward to either side of the mouthpiece.
  2. Grind your herbs to your desired consistency using the G Card. The G Pro can hold up to 500mg of material.
  3. Load your ground herb into the filling chamber. Be careful not to overfill as this will restrict the airflow.
  4. Snap the mouthpiece back on.

Now, you’re ready to go. Using the G Pro is just as easy as loading it.

Using the G Pro

To turn on the vaporizer, press the power button five times in a row. You’ll need to press the power button quickly to power up this vaporizer. The G Pro is designed this way to ensure that you don’t accidently turn it on while the vaporizer is in your back pocket. It also helps conserve battery life with an automatic shut-off feature.

Once turned on, the power button will turn red to let you know that it’s heating up. When the heating chamber has reached the desired temperature, the power button will change to green. It should only take about a minute to heat up to the right temperature.

Three minutes after you power up the G Pro, the device will automatically shut off. This conserves battery life and prevents the material from overheating. To adjust the G Pro’s temperature, simply press and hold the power button. You may have to do this a few times to cycle through to the right temperature.

Cleaning and Maintenance

Cleaning the G Pro is easy, too. A cleaning brush is included to make things easier.

  1. Make sure that the vaporizer is off and has had a chance to cool down.
  2. Remove the mouthpiece to access the heating chamber.
  3. Use the G Cleaning Brush to clean out any debris or build-up in the chamber.

Never use water or any cleaning solution to clean the heating chamber. You can remove the mouthpiece, and clean that with rubbing alcohol if necessary.

You may see some users recommending cleaning the G Pro’s internal components with rubbing alcohol. It is recommended that you do not follow this suggestion as you could damage the internal components of the vaporizer.

Be sure to also clean and replace the filter screens as needed. The G Pro comes with five to start with, but you can purchase additional ones.

The Bottom Line

The G Pro is a portable vaporizer pen that’s a great choice for a beginners or those on a tight budget. The vapor isn’t top quality, but it’s excellent for a vaporizer at this price point. It’s easy to use, offers adjustable temperatures and is small enough to fit in your back pocket.

Is the G Pro the best vaporizer for dry herbs?

Probably not. But it comes close – especially at this price point.
