The Yocan Uni is a portable box mod that works with any 510 cartridge style atomizer up to 12mm. Featuring a height and width adjuster to fit any size cartridge, this unit is designed to fit them all. A window is set into the unit on the side allowing for liquid levels to be observed so you never have to take your cartridge out until it is empty. A micro-USB charging port is available to keep the 650mAh battery up and running. A built in preheat function allows for a 10 second warm up time for your oils. Three adjustable voltage options allow for the user to get their desired experience out of the unit for every hit.
