The Nokiva hand-held vaporizer fits easily into the palm of your hand like a cellphone. It features a ceramic heating chamber, which can take up to half a gram of dried herb, with a heating time of just 20 seconds! The OLED screen shows battery life and temperature, which you can easily change from Fahrenheit to Celsius, or vice versa. With no exposed element, the Nokiva bakes, not burns. It has a food-grade mouthpiece designed to reduce heat from the device and a long lasting 2200mah battery with micro usb charging, low voltage protection, and auto shutdown (5min without use).
