The XMax® ‘Vital’ Vaporizer is for vaping with dry herbs. It does not burn your herbs due to the closed ceramic heating chamber which sits underneath the mouthpiece with ceramic filter. The temperature is individually adjustable from 100°C/212°F to 240°C/464°F. Just press the buttons to move up (+) or down (-) until the desired temperature is shown in the OLED display. The ‘Vital’ has a micro USB receptacle for charging with USB cable. With automatic shut-off function optional after 5 or 10 minutes.
