The Yocan UNI Pro Box Mod features several upgrades that take the UNI variant to a whole ‘nother level! The Yocan UNI Box Mod is now capable of precise voltage adjustment. This means that you can get to choose the temperature you get to run your cartridges on and you can do that with accuracy and with precision. Equipped with new buttons laid out conveniently for you to select and change the voltage level, the Yocan UNI Pro Box Mod delivers precise temperature selection without the fuss. You can see all the changes you’ve made on the crisp OLED screen attached to the side of the cartridge box mod battery. You can also check other settings and statuses from the OLED screen so you’re always in the know of what’s happening with your Yocan UNI Pro Box Mod. There is a significant difference between reading LED lights and visually seeing the icons representative of the device’s status on an OLED screen. It gives the Yocan UNI Pro Box Mod a more premium feel.
