Due to the plus-minus keys and the easily visible LED-display, the operation of the MIGHTY is self-explaining: As soon as the actual temperature corresponds to the individually adjustable set temperature, the device is ready for use. This is additionally indicated by a short double-vibration. Through the setting options directly on the device, the personally preferred temperature can be adjusted gradually during vaporization. The MIGHTY has a Dual-Lithium-Ion Battery Power. The battery double-pack allows a long operating life and a great radius of action. The MIGHTY can be operated via power adapter with completely discharged batteries. Full Convection Hot Air Precise electronic control Dual Lithium Ion Battery Power High Efficiency Heat Exchanger Super Precise Temperature Control Automatic switch off With the MIGHTY, as well as with the CRAFTY and the PLENTY, 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. You can use the included Filling Aid for a quick and clean filling of the Filling Chamber, which is integrated into the Vaporizer. In place of the Cooling Unit, the Filling Aid is attached on top of the Filling Chamber. The Cooling Unit assures that the vapor cools down and guarantees an optimal flavor and a rich aroma. The MIGHTY is a portable, battery-run and powerful Vaporizer of STORZ & BICKEL with a size of 14,0 x 8,0 x 3,0 cm (5,5 x 3,2 x 1,2 inches) and a weight of only 230g (0,5lbs).
