The Yocan Uni Pro Vaporizer is a newly updated design of the previous version, improving it with a adjustable voltage based output, 10s preheating functionality, and is equipped with adjustable height and width settings to neatly accommodate any and all vaporizer cartridges available on the market today. Featuring an adjustment dial and sliding lever, the Uni Pro can match with any cartridge of any length or diameter, hiding it within the recessed 510 connection tunnel. Packaged with a threaded magnetic 510 ring, the Yocan Uni Pro Vaporizer can quickly release or attach a cartridge with the magnetized threaded 510 connection. In addition, the Uni Pro Vaporizer is equipped with a variable voltage setting, allowing for minute adjustments of 0.1V within the range of 2.0-4.2V to suit all tanks with ease. Double tapping the intuitive firing button activates the 10s preheating function, gradually heating the cartridge up to vaporization levels to create a simple yet satisfying vaping experience.
