The UNI is Yocan's best-known 510 box mod — the name comes from "universal," and that's the whole idea. Its adjustable chamber changes both height and width, so it fits cartridges of any diameter or length, including wider carts that don't sit properly in slim pen batteries. The cartridge is fully enclosed, which protects it in a pocket and keeps things discreet.
Within the family, the differences are mostly size and refinement: the UNI Pro adds finer voltage steps and a larger display, while compact versions trade some battery capacity for a smaller footprint. All of them share the adjustable-dial design, preheat mode, and simple three-button operation.
Choose a UNI if you switch between cartridge brands or sizes, want your cart fully concealed, or simply want the safest "fits everything" choice in the lineup. Every UNI we ship is authentic Yocan stock, shipped from within Canada with the manufacturer warranty.
