The all new Yocan Evolve Plus XL is a thorough rework of the blockbuster Evolve Plus. There isn't anything that carries directly over from the original. The battery jumps more than 25% to 1400mAh to power the all new QUAD Quartz Rod Coil. It uses 4 stainless steel wrapped quartz rod coils to give you huge eNail like hits. The mouthpiece connection is magnetic for the added convenience and you can now control the airflow to really personalize your experience. The built in silicone jar was reworked and is now removable and has two separate compartments.
