The VAPMOD V-Mod is a super compact thick oil/wax vaporizer kit with a sleek design reminiscent of the iPod. It has a sleek, minimalist design featuring a single button for intuitive operation. The kit comes with a 510 thread screw on magnetic connector ring. You can adjust the voltage between 2.6V (Green), 3.2V (Yellow), and 4.0V (Red) by clicking the button 3 times. The unit also uses the colors to indicate its battery life. Green means 70% or more, Yellow is between 30% and 70%, and red means less than 30% battery life left. You can also preheat a cartridge by pressing the button twice. At just less than 2 inches by 2 inches and slightly more than 1/2 inch thick, this is a very compact well designed unit with ample battery life to keep you going!
