The Yocan Evolve D Plus pen vaporizer is an upgraded version of original Evolve-D, a portable dry herb pen featuring dual pancake coils for maximum vapor production, and a single-button control. The Yocan Evolve D Plus heats at around 3.2v to 4.2v, the optimal temperature for extracting the most flavor and potency from dry herbs. The Evolve-D Plus features a large heating chamber and utilizes dual coil atomizer heads for improved heating and vapor production. The base of the battery serves as a hidden storage jar for extra dry herb. The Evolve D Plus features a functional mouthpiece that may be pushed to move the dry herb closer to the coil and also simplifies the cleaning process. The integrated 1100mAh battery will provide 3 to 6 hours of vaping on a full charge and can be conveniently charged on-the-go with the included USB charging cable. The Yocan Evolve-D Dry Herb Pen is a portable and powerful device that fits your budget!
