Utillian is known for making well-priced, well-performing devices like the Utillian 620 and Utillian 722 for dry herbs and the and Utillian 5 for extracts. The Utillian 421 is no different - it’s an update of the older 420 and builds on an already great solid box-type design. The Utillian 421 is a simple and user-friendly dry herb vaporizer with a single button interface, clear LED display, a long battery life, adjustable airflow, and a glass mouthpiece for keeping vapor pure. The Utillian 421 has a simple box-style body with rounded edges and an anodized steel finish. It’s only 4 inches tall making it pretty portable and stealthy. On the side of the 421 is an oval-shaped power button that is used to turn it on/off and to cycle through any of the 6 pre-set temperature ranges.


  • Glass Mouthpiece: The neutral mouthpiece preserves the flavor and allows you to fully experience the vapor without compromising its quality and losing flavor.
  • Ceramic Heating Chamber: the Utillian 421 uses conduction heating and has a ceramic heating chamber that holds up to 0.3g of dry herb. It heats to any of the pre-set temperatures in 60 seconds (356°F, 374°F, 392°F, 410°F, 428°F, and 446°F.)
  • Battery: The 421 is powered by a 2300 mAh lithium polymer battery rechargeable via micro-USB. A single charge should be good for 6-8 sessions or 60 minutes of continuous use.
  • Adjustable Airflow: The airflow valve is located at the bottom of the 421 and allows users to control draw resistance.  For bigger clouds and tastier vapor, decrease the airflow - and increase for less dense, but cooler vapor.

How to Use

  1. Unscrew the mouthpiece.
  2. Load your dry herb into the heating chamber.
  3. Use the mouthpiece to tamp down / pack the herb.
  4. Press the power button five times rapidly to turn the U421 on.
  5. Press and hold the power button to cycle through the preset temperatures.
  6. Wait till it reaches your desired temperature and start vaping.

Frequently Asked Questions

  • How long does the battery on the Utillian 421 last? The 421 has a 2300mAh battery which is good for up to 6-8 sessions. That should be enough to sustain a whole day of vaping (for most users). To save more power, the 421 has an auto-shutoff feature which turns it off after 7 minutes of inactivity.
  • How big is the Utillian 421? The 421 is only 4 inches tall, and an inch thick – definitely something you can quickly stash in your pocket or a purse. However, since it also features a glass mouthpiece – we highly recommend also having a carrying bag to keep it safe.
  • How much dry herb can you load in the Utillian 421? The Utillian 421’s ceramic heating chamber can hold up to 0.3g of dry herb – more than enough for a solo session.
  • Does the Utillian 421 have adjustable airflow? Yes, it does. It’s a pretty surprising feature to see on a device at this price. Having adjustable airflow allows you to either take long slow draws or heavier sips. There are also lines around the valve that indicate draw strength.
  • What are the Pre-Set temperatures on the Utillian 421? The current and set temp settings are indicated by the LED display: 180°C/356°F | 190°C/374°F | 200°C/392°F | 210°C/410°F | 220°C/428°F | 230°C/446°F
