DaVinci IQ 2 Review

Review Summary

The DaVinci IQ 2 is a high-end vaporizer that produces tasty vapor in a convenient, portable package. It uses zirconium elements that keep the vapor cool even though the device itself can run hot. It also comes with a nice array of accessories that allow you to choose how you want to vape. If you want a high quality portable weed vaporizer, then the DaVinci IQ 2 is one of the best options available.


Davinci IQ 2 Vaporizer Design

The original DaVinci IQ was released late 2016, and it’s been users and critic’s favorite thanks to special and unique features. DaVinci has released the Miqro on July 2018, which is essentially a smaller version or the IQ, but there were no other major releases. Until today. 

DaVinci just released the IQ 2, which builds upon the strong aspects of the original unit. It has the same general look and feel, but a lot has changed under the hood. The IQ 2 is primarily a dry herb vaporizer but is also compatible with Solid concentrates.  

Kit & Accessories:

In the box:

Davinci IQ 2 Kit
  • Davinci IQ 2 Vaporizer
  • Dosage Pad & Ceramic Extract Disc
  • Flat & Extended mouthpiece
  • Alcohol wipes, Organic cotton pads
  • Charging cable, Manual, Spare pick tool
  • Dosage Pad

The Dosage pad is a little Ceramic canister that can be used with Dry herbs or allow the use of Solid Extracts.

With dry herb: the dosage pad fits 0.2gr of dry herbs instead of the 0.5gr that fits into the oven. So it can be used as an oven reducer for microdosing. 

Davinci IQ 2 Glass spacers

With Extracts: also included in the IQ2 kit, is a Ceramic Disc that can be inserted into the Dosage Pad, and used with Solid Extracts such as Wax or Dab. 

As always, I recommend avoiding the use of concentrates in your primary dry herb vaporizer. Over time, residue will build up, and everything will become sticky. You should use a dab pen for your extracts and use this vape only for dry herbs. 

Mouthpiece options

Davinci IQ 2 Mouthpiece

The IQ2 comes with a flat mouthpiece installed and ready to use, and there is another (extended) mouthpiece in the box. The extended mouthpiece can also be used as a 10mm adapter for various accessories or water filtration devices (View in Store). 

Inhaling from the extended mouthpiece feels more natural, and the longer airpath helps to cool down the vapor. This was my favorite mouthpiece by far. The downside is that it reduces portability a little.

Both mouthpieces are made from Zirconia, which is an advanced, pure material that has similar properties to Ceramic. 

18650 Battery

Davinci IQ 2 Battery

The IQ2 uses a replaceable 18650 battery (view on Amazon), and there is one included in the box.

The battery lasts for around one hour of continuous use, which is not bad at all. But when using the micro USB port that’s on the device to charge the battery (inside the device), it takes 6 hours to reach a full charge. An external charger can reduce the charge time to three hours, but most users do not want to pop batteries in and out of the vape and a charger constantly. 

Additional Accessories 

Glass Spacers: There are optional 10mm and 6mm glass spacers available for the IQ. They are inserted into the herb chamber, reducing its capacity for users who want to use less herb. So, they give you the choice of three different oven sizes:

  • The full oven without any spacers
  • A roughly half-sized oven with the smaller 6MM spacer.
  • And the smallest oven size when using the larger 10MM spacer.

The spacers are great accessories because they make efficient use of the oven and your weed supply (View in Store).

External Charger: There is also an optional external charger for the removable 18650 battery, which halves the charge time of the included micro USB cable. You can purchase more 18650 Batteries on (view on Amazon), and there is one included in ) and always have one in the charger and one in the vape.

Design & Features:

The original IQ featured an exterior made from sandblasted Aluminum, and that has been changed to brushed Aluminum with the IQ2. It makes the device a little smoother. It feels very well made; it is sturdy and has a good balance while holding. 

Both the top and bottom of the device open up with a latch mechanism to expose the internal components of the IQ. 

On the bottom, there is an oven with a nice funnel-shaped sink that slides the herb right into the oven. The oven is made from Glass and Ceramic and is shaped like a deep cylinder. 

The top latch opens to reveal the battery, the flavor chamber, and a small pick tool. Both lids are magnetic and easily pop on and off. 

Zirconia Pearl

Davinci IQ 2 Zirconian Pearl

The bottom lid of the IQ has a Zirconia Pearl (View in Store) connected to the bottom lid that slides right into the oven. It reflects heat back into the oven, resulting in an efficient and even “roast” of the herbs.

The Zirconia Pearl can be adjusted to reduce the size of the oven, but I suggest just leaving it in the default position and not messing around with it. The reason is, when screwing it out too much, it sticks out, and the latch doesn’t close smoothly. When it is screwed all the way in (or up to halfway), there is no problem at all.  

Flavor Chamber

Davinci IQ 2 Flavor Chamber

Just like the previous IQ, the IQ2 features a “flavor chamber,” which cools down the vapor, and can double as a small storage container. The flavor chamber (View in Store) sits under the top lid and can be pulled out and opened with the small pick tool that’s tucked right next to it. You can place enough herb there for about a session so you can have an extra bowl in the device, ready to vape. The flavor chamber is made from Zirconia, and it cools down the vapor as it passes through. 

Adjustable Airflow (5 levels)

Davinci IQ 2 Adjustable Airflow Dial

The bottom lid of the IQ includes a new airflow control dial that has four levels of airflow. It can be turned to reveal one to four holes that will increase and decrease the amount of air that can pass through. This is important and has significant implications for the type of vapor you can get. 

Increasing the airflow will cause air to pass through the oven faster, resulting in cooler, less dense vapor. Closing the dial and reducing the airflow will result in a warmer, thicker vapor. 

LED Display

The IQ2 features the same LED display we’re used to from the original IQ.

It is a small LED grid, that can display temperature levels and various settings. The IQ 2 has a “stealth mode” that can be activated by pressing the power button together with the down arrow once to dim the LEDs.

How to use

Davinci IQ 2 Power Button

The IQ2 has two modes: Smart path or Precision mode. They both toggled and set tight from the device. Smart Path mode gradually increases the temperature by 20 degrees as you vape, and you can choose from four preset Smart Paths or customize your own. Doing so is very simple, and it is an excellent option for anyone who likes to adjust the temperature as they vape. 

Basic operation: 

  1. Click the power button five times to unlock and activate the device
  2. Select one of the four preset Smart Paths

View the official user manual here.

The IQ will automatically heat up and vibrate when the designed temperature has reached. 

When on smart path mode, the IQ will gradually increase the temperature over an Eight minutes session.

  • Mode 1: starts at 350F and increases to 370F
  • Mode 2: starts at 370F and increases to 390F
  • Mode 3- starts at 390 and increases to 410F
  • Mode 4: starts at 410 and increases to 430F

Temp check & Precision mode: Pressing the power button once will display the current temperature when in smart-path mode. While the temp is displayed, you can enter precision mode by pressing the up or down arrows, and set a precise temperature between 350-430F.

Other functions:

Boost mode: Pressing and holding the power button will quickly boost the temperature to 430°F. The LEDs will show up arrows, and the temperature will increase. When the button is released, the IQ enters a “stand-by” mode that will cool the device and conserve herb and battery life. To return to the previously set temperature, press the up or down button once.

F °| C ° Toggle: Click all three buttons at once to toggle between Fahrenheit and Celcius. 

Factory reset: Turn off the device and press all three buttons together for ten seconds. The IQ2 will vibrate and reset to factory settings.

Cleaning & Maintenance 

As with any other vape, I highly recommend maintaining your vaporizer and cleaning it when required. You should empty your oven and remove derbies after every session.

Every 8-12 uses the IQ2 needs a deep-clean which includes cleaning the following components with ISO alcohol:

  • The “flavor chamber” and the mouthpiece.
  • The oven and Zirconia pearl (View in Store).  
  • Any latches or moving parts that collected residue.

The IQ2 has a lot of unique features such as the flavor chamber and the zirconia pearl, which help it stand out from most vapes. But this comes at a price- higher maintenance compared to other vapes. All the parts are easy to clean, but there are a lot more of them than in other vapes, so cleaning takes a little longer. 


Empty your oven immediately after a session– Leaving cashed herb in the oven after a session will cause it to stick, and it will be harder to remove. Empty your oven after every session as soon as the herb is cashed.

Use a good grinder– Properly ground herb means more surface area, which means and more efficient and even extraction of ingredients from the herb. My favorite grinder for vaping is the SLX grinder (Review). It has a Ceramic coating, so nothing sticks to it, and it grinds the herbs to the perfect vaping consistency. 

Find the perfect inhale– Use the Air dial to adjust the airflow to a comfortable draw resistance. You should take deep, slow inhales and give the oven a few seconds between inhales to regulate the temperature. Here are a few tips to getting more vapor from your weed vape.

Performance & Vapor Quality

Overall performance 

Davinci IQ 2 Dry Herb Vaporizer

The original IQ produced some of the best, most dense vapor I ever experienced, and the IQ2 is no different. After playing around with the Air Dial, I started loving the idea, and I wonder how come no one did that earlier. We often see adjustable airflow in liquid vaporizers, but Davinci incorporated that into this new vape. I think that this is only a dry herb vape that features adjustable airflow. 

Vapor Quality

The IQ2 produced clean, flavorful vapor, and preserved the delicate flavors of the terpenes. As mentioned earlier, the IQ2 uses a glass and zirconia airpath, free of plastic, metal, and electronic components. I experienced the best vapor at around 390F at precision mode or the second and third smart paths. For heavy hitters- the IQ2 can heat up to 430F, which is higher than even the Mighty’s 410F. The higher temperature can be used for Extracts, but I do not recommend going over 420F with dry herbs.

The vapor was surprisingly thick, especially for a conduction vaporizer. The not-so-secret secret is the zirconia pearl in the oven that helps to regulate the temperature and provide a nice even vape to the herbs. The long airpath helps to cool down the vapor, particularly with the extended mouthpiece. 

Battery performance

The IQ2 lasted around 6-8 sessions before it needed a recharge. That’s not bad, and there are no complaints there, but it takes 3-6 hours to charge. This is long recharge time. For example, the new Crafty+ has a 6 -7 bowls runtime but takes an hour and a half to charge (vs. Davinci’s 6 hours in the device or 3 hours with an external charger).  

What could have been better

The IQ2 is an impressive vape overall, and there is no doubt that a lot of thought and engineering went into making it. With that said, here are a few things that I think could have better-

Replaceable battery– I know some users like to have a replaceable battery, which means that they can charge a bunch of batteries and stayed powered for long periods even when unplugged from the grid. But this is a problem that is easily solved with a power bank or an external battery that can recharge the device while on the go. So I would have preferred to save the space of the latch mechanism and simplify things by having a permanent internal battery that hopefully charges faster. 

Mouthpiece– Generally, I prefer extended mouthpieces over flat. With flat mouthpieces, you need to place your lips directly on the device. The device can get hot during extended sessions and feels uncomfortable on the lips. I think a permanent “short” extended mouthpiece would have been better for 90% of people. The extended mouthpiece that is included is excellent but maybe just a bit too tall to allow convenient carry. Using a permanent, short mouthpiece would have saved the mechanism that allows to swap the mouthpieces and make space for a larger battery or other components.
