Yocan Uni Box Mod - A Quick Intro

Yocan is known for releasing well-crafted high-quality devices at very affordable price points, and the Uni box mod is no exception to that trend. Meet the world’s first universal width and height adjustable box mod that works beautifully with oil atomizers of all different sizes.

The Yocan Uni box mod was designed for a more discreet vaping experience while on the go. The Yocan Uni mod features a 510 threaded connection, a magnetic 510 adapter, 3 different voltage settings, and a 10 second preheat function for the best quality vapor. 

How To Use Yocan Uni Box Mod?

The Yocan Uni box mod is incredibly easy to use and quickly become familiar with thanks to its straightforward design. The Uni doesn’t require much cleaning at all and there are no complicated hoops to jump through to achieve high-quality vapor. Just load your atomizer, choose your ideal voltage and enjoy!

1. How To Operate Yocan Uni Box Mod

Take the 510 magnetic rings and push them into the device, then proceed with installing your atomizer. You can adjust the height and diameter settings to best fit the atomizer by using their designated buttons. When you have the atomizer in place, click the power button 5 times to turn on the device. 

To activate the 10 second preheat function, simply press the power button 2 times, then 3 times to navigate through the voltage settings and the three lights located near the top will indicate what setting you are on.

One light is the lowest voltage setting, two lights represent the medium voltage and three lights will indicate that you are on the highest setting. When you have chosen a voltage, bring the unit to your mouth and hold down the button as you inhale through the mouthpiece. 

2. How To Get Best Vapor Quality

Most people recommend sticking to the highest voltage setting for the highest vapor quality. Some other ways to ensure powerful vapor include making sure that the unit is fully charged, using the preheat function on thicker oils, and taking long slow draws. 

3. How To Clean/Maintain It

You can take care of your Yocan Uni Box Mod the same way you would any other vaporizer. Start by taking a cotton swab dipped in isopropyl alcohol and wiping away any dirt or grime found on the 510 thread ring, rinse, and then dry.

You can wipe down the Uni box mod body with a damp cloth if you notice any dirt or dust has accumulated on it. Always make sure to keep the mouthpiece that you are using clean to avoid bacteria or clogging.


Like most Yocan devices, the Uni box mod is a high-quality, well-built, and durable device at a very low price. This unit has a nice solid feel with sturdy buttons and a strong high-quality magnetic connection. The Yocan Uni has a beautifully sleek design and works efficiently to provide the best quality vapor possible. 

Temperature settings

The Yocan Uni Box mod has 3 different preset voltage settings to choose from including, 3.4v, 3.7v, and 4.2v. The three lights towards the top of the device represent the current-voltage setting of the Uni:

  • One light = Lowest voltage setting, 3.4v
  • Two lights = Medium voltage setting, 3.7v
  • Three lights = Highest voltage setting, 4.2v

Battery & Power

The Yocan Uni box mod is packed with a powerful 650mAh capacity battery that can last over 200 puffs on a full charge depending on the drawing intensity. The Uni can be charged via USB and will take about one hour to fully charge. 

Versatile Height and Diameter

The Uni box mod features Yocan’s patented adjustable height and diameter design to fit atomizers of any size. Simply push the height button up or down to adjust the height of the Uni box mod, then use the diameter dial to adjust the inner diameter of the box.

Who is the Yocan Uni Box Mod for?

The Yocan Uni is made with portable users in mind. This device was designed for a discreet vaping while on the go. This is the best box mod for those who enjoy variety and need a unit that can handle it all. The Uni is for the people who are tired of being stuck with whatever a single manufacturer offers. 

Who is the Yocan Uni Box Mod not for?

Those who tend to keep their vaping sessions at home or aren’t too concerned about staying discreet may not find much value in what this box mod offers. There are plenty of vaporizers on the market that could be a better fit.
