Utillian 421 Herbal Vaporiser



Born in 2014, Utillian (Canadian brand) is synonymous with quality and reliability (not just my opinion), using only the highest-grade materials to create herbal vaporisers for those that like to take their vaping to a “higher” level! Their premise is simple with a goal of creating high precision units for all levels of vaping expertise whilst providing a pure, smooth and potent experience for all.

TIP: A one year limited warranty is provided by Utillian.


The Utillian 421 is an elite entry-level herbal (dry) vaporiser and is the upgraded version of the Utillian 420. Sturdy with a minimalistic design, this vape is just slightly larger than the palm of my hand and will be a very easy device to transport about. The body is anodized aluminium, which is pretty rare for an entry level vaporiser and will help to keep it looking good for longer.  The internal rechargeable battery is rated at 2300mAh and should see you through 60 minutes of battery life before a recharge is required.

A very simple herbal vaporiser to master as there is only button with a small OLED screen for you to navigate. The OLED sits upon the very top of the device and will show you the set temperature, battery strength as well as allow you to see the temperature progression as the device heats up. Utillian has provided 6 pre-set temperatures for you to choose between (more on that soon).

The Ceramic heating chamber is rather roomy and heats via conduction, providing a pure and flavoursome experience. Speaking of flavour, the Utillian 421 has an isolated pathway for your vapour helping to keep it pure. The vapour pathway within this nifty little vaporiser is elongated with an extended glass mouthpiece to further smooth out and cool down the vapour. Lastly, airflow has been improved with a new airflow valve on the base of the unit. Increase and decrease via a simple twist of the dial.

TIP: I am yet to come across a review of this vape that does not speak to the Utilllian’s superior vapour quality.

Measurements: 50 x 25 x 90mm (120mm to top of mouthpiece)


The chamber is crafted from Ceramic and utilises conduction as its heating style. For those unaware, conduction is the heating of your herbal material via direct contact with a heated surface, in this case the ceramic walls of the entire chamber will radiate heat. The Utillian 421 will take approximately 25 seconds to reach your desired temperature and the following 6 temperatures are provided;

  • 180°C
  • 190°C
  • 200°C
  • 210°C
  • 220°C
  • 230°C

180-220°C is the general temperature range for effective dry herb vaping (marijuana) but in this case they have included a temperature out of this range (230°C). Why would you need this? I would use this mode at the end of my dry herbal vaping session for that added boost of extraction and vapour. The Utillian 421 has a 7-minute auto shut off feature to keep you safe as well as to conserve battery life. You are able to turn off your device at any stage before the 7 minutes is up if you would rather a shorter session.


Utillian have calibrated the airflow on the 421 allowing you to adjust it to your exact liking. This may not sound like a big deal, but this airflow system definitely makes a noticeable difference in the amounts of vapour that can be produced. It all up to you and your style of vaping. Airflow will also play a role in the flavour and smoothness experienced.


2300mAh capacity is pretty good for a herbal vape and should give up to 60 minutes of continuous use before a charge is needed (or approximately 6-8 sessions). A Micro USB Charger is provided in this kit and a full charge will take approximately 90 minutes. The OLED screen will illuminate during charging showing you the status.
