The CRAFTY’s compact construction with a single Lithium-Ion Battery Power is complemented by a practical one button control: You turn on the CRAFTY with only one keypress. It then heats up automatically until it reaches the default set Basic Temperature of 180° (356°F). With a double-click on the button, you activate the booster-temperature of 195°C (383°F). When the set vaporization temperature is reached, it is signaled through a short double-vibration and the LED-indicator lamp: The LED changes the color from red to green. Full Convection Hot Air Precise electronic control Single Lithium Ion Battery Power High Efficiency Heat Exchanger Super Precise Temperature Control Wireless Bluetooth Multifunction App Automatic switch off With the CRAFTY, as well as with the MIGHTY, PLENTY, and VOLCANO, vaporization functions on the basis of a full hot air convection heating combined with conduction. The convection heating provides an immediate and continuous vaporization, whereas the conduction ensures that there is vapor created from the very first breath. The Filling Chamber, which is integrated into the vaporizer, is to be filled with plant material (This is facilitated by the included Filling Aid) and the Cooling Unit with Mouthpiece is to be attached. The Cooling Unit makes sure that the vapor cools down and guarantees optimal flavor and a rich aroma. The CRAFTY is the smallest STORZ & BICKEL Vaporizer with a size of 11,0 x 5,7 x 3,3 cm (4,30 x 2,2 x 1,3 inches) and a weight of 135g (0.3 lbs).
