To set up a USB-C rechargeable vaporizer, start by charging it fully with a standard USB-C cable and a 5V/1A adapter (not a fast charger). Then clean the mouthpiece and chamber with isopropyl alcohol, let everything dry, and do a few dry pulls to check airflow. Start on a low temperature and take short puffs to get a feel for the draw. Keep the device upright when storing, and you're good to go.
