Ease of use

Today we will take a look at the latest portable E-Nail device from Yocan Vaporizers. Yocan Vaporizers currently offers a variety of dry herb, oil, and concentrate vaporizers. We have previously reviewed several of their products, including their Evolve 2.0, Uni Pro, Armor, Vane, Trio, and most recently, their Stix. The full retail price for the Yocan Rex kit currently runs for $49.99 on their website. For this review, let’s examine their Yocan Rex portable E-Nail.

  • Solid design
  • Efficient performance
  • User-friendly features
  • Pocket-size portability
  • Perfect for beginners


  • Slightly harsh taste

Recommendations: Additional lower voltage settings would be appreciated.



The Yocan Rex is a pocket-sized portable E-Nail that’s perfect for beginners

The Rex delivers the user-friendly experience of the DabX rocket mk1 or the Freeze Pipe E-Nail with the stealthiness of a wax pen. At first glance, it looks like an upside-down wax pen, no different than their own Evolve Plus or the Utilian 5. While the precise temperature settings for the Freeze Pipe E-Nail and The Wand by Ispire feel more accurate than the Rex, it is just as accessible and portable as the DabX rocket mk.1. The Yocan Rex is also incredibly adaptable as it works with both glass and silicone rigs. Although the Rex can accommodate most glass rigs, the Rex unit had better airflow with the Waxmaid products using the silicone cover. The Rex also uses a 1400 mAh battery that has the USB-C charging port on the side.

When you first open the Yocan Rex, you will find the following:

  • Yocan Rex unit with silicone cover
  • Additional QTC atomizer
  • Stainless steel dab tool
  • USB-C charging cable
  • User manual



Although the Rex is able to generate bigger clouds, the flavor can be slightly harsh beyond the lowest setting

Although the Rex is extremely convenient to use, the only drawback is the flavor. The Yocan Rex features their own QTC (Quartz Tri Coil) coils with a honeycomb chamber, which is similar to one of the coils included for the Utillian 5. Although these coils produce an excellent amount of vapor, they can taste harsher than the ceramic heating plate used for the DabX rocket and the quartz dish used for the Freeze Pipe E-Nail and the Wand by Ispire. In particular, live rosin tastes slightly harsh beyond the lowest setting. As a result, I’d only recommend live resin sauces, sugars, diamonds, and shatter for any of the higher settings. Overall, I found the lowest setting on the Rex to be sufficient enough to get the best flavor out of most concentrates.

Rex expanded

Similar to the DabX rocket, the Yocan Rex is designed for maximum ease of use with its three main temperature settings:

  • 3.2v (white) – best for live rosin
  • 3.7v (blue) – best for live resin sauces, sugars, diamonds, shatter
  • 4.2v (green) – best for larger rigs/bongs

Operating the Rex for the best performance:

  • Once you charge the Rex, unscrew the battery from the QTC atomizer along with the attachment base
  • Load your preferred extract onto the coils of the atomizer
  • Reattach the QTC atomizer along with the attachment base to the battery
  • Insert the Rex with the attachment facing down onto your dab rig/bong
  • Turn on the battery by pressing the power button five times quickly
  • Adjust the temperature setting by pressing the power button three times quickly
  • Adjust the airflow valve to your preference
  • Activate the heating cycle by holding down the power button with one long click
  • Inhale slowly through the mouthpiece of your rig/bong
  • Deactivate the heating cycle by pressing the power button with one short click if needed
  • Turn off the Rex battery by pressing the power button five times quickly

Yocan Rex is most similar to the Utillian 5 in terms of battery life and performance

The closest comparison for the Yocan Rex is the Utillian 5, which has similar battery life and strength. However, the flavor using the Utilian 5 with the glass bubbler tasted less harsh, due to the lower voltage settings. In addition, the Utillian 5 is a bit more versatile than the Rex since it also works with 510-threaded cartridges. In terms of cleaning and maintenance, it is also similar to the Utillian 5 as there are very few parts to clean. The only parts to worry about are the coils within the atomizers, which can be cleaned with one of the Q-Tips supplied in the kit. Then, all that’s left to do is to wipe down any residue on the base of the battery and near the attachment base.



All in all, the user-friendly features of the Yocan Rex will appeal to both veteran users and newcomers

The final verdict: I would highly recommend Yocan Rex for its solid design, efficient performance, user-friendly features, and pocket-sized portability. Although you will need a rig, the Rex unit itself fits comfortably in your pocket. The Yocan Rex works well with most concentrates; however, live rosin tastes harsh upon the higher settings. The Yocan Rex also worked more efficiently with the silicone products from Waxmaid than any of my traditional glass rigs. The Yocan Rex portable E-Nail is available in black, silver, red, green, and blue colors, which can be purchased through their website here.
