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 356°F (180°C). With a double-click on the button, you activate the booster temperature of 383°F (195°C). 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 AirPrecise electronic controlSingle Lithium Ion Battery PowerHigh Efficiency Heat ExchangerSuper Precise Temperature ControlWireless Bluetooth Multifunction AppAutomatic switch offWith the CRAFTY, as well as with the MIGHTY, 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 4.3 x 2.2 x 1.3 inches (11.0 x 5.7 x 3.3 cm) and a weight of 0.3 lbs (135 g).
