Myster Splitbox Dual Cart Battery

Split the flavor, keep the control

Load one cartridge when you want to keep it simple, or run two when you want to rotate oils, switch strains, or blend your session. Since each side has independent voltage control, this dual cart battery lets you keep one cart cool and flavorful while turning the other up a notch. It’s a smart fit for those who want more options, more control, and more flexibility—dual carts, independent voltage, and a water pipe adapter give you just that.

Smooth on the draw, slick on the switch

The Splitbox is not just a two-cart novelty. It also brings the everyday must-haves that make a 510 thread vape battery easier to love, including simple draw-activated firing, a preheat function for thicker oils, airflow adjustment for a more tailored pull, and a removable magnetic silicone mouthpiece for added convenience. Add in the LCD screen and the included adapter for water pipe use, and you’ve got a dual cartridge battery that can go from pocket-friendly to water-filtered in a snap.
