The SteamCloud Mini oil vape mod is compatible with 510 threaded oil cartridges. All you have to do is screw on the magnet adapter to the 510 thread and then you can drop the cartridge right into the vape battery and begin using it. The 650mah battery now comes with variable voltage, pre-heat functionality, and you have the option of purchasing a wax cartridge atomizer. It'll last all day and is a big improvement over the SteamCloud Stylus vape pen. Buy this now so you can be super discreet wherever you go.
