The Yocan Evolve Plus XL, like most Yocan wax vaporizers, is outfitted with a built-in wax container which makes for a more convenient vaping experience. Instead of carrying an additional jar or wax container in your bag or in your pocket, you can conveniently carry a certain amount of material to make sure you never run out of extracts. This is perfect for people who are always on-the-go and for those who like to vape on their feet. The Yocan Evolve Plus XL Vaporizer ensures that you always have what you need in terms of power and material availability. You can also carry two types of materials at once since the wax compartment found on the Yocan Evolve Plus XL features a dual compartment to separate runny waxes from the thicker ones. Enjoy various concentrates and carry more than one type with this genius design.
