The Yocan UNI Pro Box Mod battery is the latest addition to Yocan’s already versatile line of oil cartridge batteries, now bringing a new level of variable voltage control that’s worthy of the sophisticated cannasseur (one who enjoys the consumption of cannabis, and studies the many varieties and their differing effects)! Yocan has made the UNI Pro more powerful, more practical, more functional, and with looks that are reminiscent of the capabilities and the functionalities that you loved and will love more on this new and updated version.
