The Yocan Uni Universal 510 Thread Box Mod is the world’s first universal width and height adjustable box mod that will work with all the oil atomizers.
On the side, there is a height adjust button, so you don’t need to worry if your atomizer is too tall or too short.
The Yocan Uni also features on the top of the box mod, a diameter adjustment dial, which will adjust to fit all kinds of oil atomizers with different diameters.
The Yocan Uni Universal 510 Thread Box Mod supports cartridges up to 12mm in diameter.
These are the patented designs of Yocan.
The Uni is powered by a built-in 650mAh battery and supports a preheat function that warms up your oils before the first use, which will last for 10 seconds. Users can customize their vaping experience with an adjustable voltage option featuring three power levels.
