Improving on an already impressive concentrate vape, the Yocan Evolve Plus Vaporizer Pen expands on its predecessor (the Evolve). With an upgraded battery and a larger chamber, this wax vaporizer is able to extend your vape sessions tenfold. The coolest addition to this new version is the built-in jar which screws directly into the bottom of the vape. The inside of this section is lined with neon green silicone to keep your dabs from sticking or leaking. The Evolve Plus Vaporizer Pen also comes with a USB charger and a cleaning tool.
