The updated Yocan UNI Pro 2.0 Box Mod features a more durable metallic body and a USB-C port for faster charging. It comes with the same total voltage and control layout that made the UNI Pro one of the best cartridge vaporizers on the market. Just like the original Yocan UNI Pro, the UNI Pro 2.0 adds an unprecedented level of customization to using your pre-filled cartridges by utilizing an adjustable cartridge slot that works with any size 510-threaded atomizer tank. Eliminating the need to own multiple vape batteries for cartridges with different sized widths & lengths, the UNI Pro 2.0 is equipped with an innovative slider on the outside of the battery that gives you full control over how far your cartridge or atomizer sticks out, and a dial that changes the diameter to fit different tank widths.
