The ergonomic design of the CFC Vaporizer makes it super portable. Easy to read and control, you can view both your vape's temperature as well as its battery life on the convenient OLED screen. The temperature is fully adjustable and has a range of 140°F-446°F. The CFC goes into a standby mode until you are ready for your next session. This prevents overheating and conserves both battery and herb. Built with medical and food grade materials, this dry herb vaporizer is 100% non-combustion. The CFC Vaporizer charges fully in 2.5 hours. This portable vape also comes with a cleaning brush, USB charging cable, and instruction manual.
