Another incredible addition to the wax pen lineup is the Yocan Regen. The Regen and Evolve Plus are similar in appearance and nothing else is same between the two. The varying voltage level of the battery permits to choose a desirable heat level. This makes it compatible with the kind of material that you're loading. Vapers will get 3 different preset voltage settings. These are 3.0V, 3.5V, and 4.2V. The 3 lights above the button will indicate the setting that you are currently on. One light means 3.0V, two lights indicate 3.5V, and all the three lights means it is at the highest setting, that it is at 4.2V setting. The magnetic mouthpiece makes the reloading procedure easy and hassle free. The Regen makes the most of the Triple Quartz Coil. However, one can choose the Dual Quartz coil, if low heat is preferred.
