You love vaping, but you don’t want to be forced to stay home every time you do it. Let’s face it – desktop vaporizers aren’t exactly travel-friendly. Portable vaporizers are one option, but most models are still too large and not discreet enough for on the go use.

Vape pens are the smallest, most discreet vaporizers on the market. And while there are many models to choose from, the Micro G Pen from Grenco Science is one of the best you can buy.

[alert-success]Heck, even Snoop Dogg himself jumped on board and has his very own Micro G model –complete with his signature.[/alert-success]

So, what exactly does this pen have to offer? How well does it perform? We answer all this and more in our detailed review below.

What is the Micro G, and Who Is Grenco Science?

The Micro G is a vape pen created by Grenco Science that’s designed for use with concentrates.

While this pen isn’t compatible with dried herbs or e-liquids, it’s one of the best choices when vaporizing waxes and essential oils.

The Micro G is incredibly lightweight with a matte black exterior that’s easy to grip.

At just 4 inches in length and less than 1 inch thick, this pen easily fits in the palm of your hand.



It’s extremely portable and one of the most discreet vape pens available.

Grenco Science, the maker of this pen, has been around for quite a while now. The company manufactures a wide range of portable vaporizers, and serves customers all over the world. Aside from the micro G, Grenco Science also produces a G Pro, the G Slim, and the G Pen. They’ve partner with Snoop Dogg, Taylor Gang, Black Scale, Fader100 and a variety of other brands and artists to offer unique vaporizing products.

How the Original Micro G Works

The Micro G is simple and easy-to-use, and loading it with waxes or oils is a much simpler task than with other vape pens.

Oils and waxes are placed directly on top of the screen just above the coil, and the heating element vaporizes the material by drawing air in through the sides of the pen. You’ll notice holes on the silver band just below the mouthpiece. These holes are what draw air into the pen.

It’s a simple concept, but many other pens seem to combust, or burn, waxes and oils rather than vaporize them. The Micro G is different. As long as you follow the instructions properly, your material will never combust or burn.

How to Load the Micro G Pen

How to Load the Pen

Loading the Micro G is simple. Remember, this pen is only compatible with waxes and oils. Do not attempt to fill it with dried herbs or e-liquids.

To get started, remove the mouthpiece. Next, load the filling chamber with your concentrates or oil using a dabber. The oil or wax should sit on top of the filter screen. Now, simply replace the mouthpiece, and make sure all pieces are tightly secured.

When you’re ready for use, press the power button five times in a row. The button should flash blue. To turn on the heating element, press and hold the power button again. Once the heating element is engaged, the coil will stay lit for about 15 seconds before it turns off automatically.

If you’re using oils, the oil will melt down through the filter screen and onto the heating coils, which will vaporize it. Holding the power button down for 5 to 10 seconds before inhaling will give your oil some time to heat up and provide you with a thicker hit.

How to Charge the Pen

With the Micro G pen, you have two options when it comes to recharging.

Each kit comes with a wall adapter and a USB charger, so you can choose to plug it into a wall socket, or into a laptop or desktop computer to charge.

While it’s recharging, the pen’s light will stay red. Once the red light turns off, the pen is charged up and ready to use.  You can also upgrade to their new USB charger (image right) for a faster charge.

How to Clean the Micro G Pen

To maximize the life of the Micro G’s coil, regular cleaning is recommended. To help with this, Grenco Science includes three cleaning tips in the kit.

Cleaning any excess essential oil or wax residue is important because if this residue builds up, the pen will get clogged. Soak a Q-tip in rubbing alcohol or use the cleaning tips to gently remove any remaining residue buildup.

You want to ensure that you clean the connection point of the battery, around the base of the titanium cylinder, and the exterior part of the coil.

Refrain from soaking any of the pen’s components in the rubbing alcohol or any other type of cleaning solution as this could damage the parts. It’s also recommended that you do not clean the interior of the coil where the heating element is located. The heat from the heating element will burn away any excess residue and eliminate any bacteria.

The included G Tips are conveniently loaded with 70% isopropyl alcohol, which makes cleaning a breeze. You can purchase additional G Tips online for under $10. Each box comes with 15 packets of tips.

The great thing about these cleaning tips is that you never have to worry about using the wrong type of alcohol or using too much. Every tip has just the right amount of rubbing alcohol to ensure that your parts are cleaned safely and effectively.
