The Yocan UNI Mod has everything you look for in a push button, variable voltage vaporizer including a patented design. With a slim design and standing at approximately two (2) inches tall, this vaporizer is concealable, easy to use, affordably priced, and is adjustable to work with every oil cartridge currently sold. Its primary feature are knobs that adjust the height and width of the cartridge so that any cartridge will fit perfectly. They use a magnetic adapter in conjunction to enhance the secure connection for your prefilled 510 thread cartridge. It has a two-click (2) preheat function that will continuously provide low-voltage to warm your prefilled 510 thread cartridge until you turn it off. There are three (3) power settings to toggle between and they are indicated by individual led lights. A window outside of the prefilled 510 thread cartridge chamber allows you to keep an eye on the contents of your cartridge. If you want a concealable push-button vaporizer that was specifically designed for any prefilled 510 thread cartridges, then the Yocan UNI Box vaporizer is your vaporizer.
