VapmodTech has invented their best seller V-Mod with the new second version. The main difference between V-Mod and V-Mod 2 is that the second version has haptic feedback, that notifies once preheat function is ready to use. Other than that V-Mod 2 has the same features such as long-lasting integrated 900mAh battery with variable voltage from 2.6V to 4.0V, 510 thread magnetic connection, preheat mode and pass-through charging through Micro-USB port. The VAPMOD V-MOD 2 has a sleek, minimalist design with single-button for intuitive operation. At just less than two inches by two inches and slightly more than half-inch thick, this is a super portable unit with ample battery life. V-Mod 2 has 510 thread connection with the magnetic ring and is compatible with all mini oil cartridges up to 10mm wide between 0.5 and 3.0 Ohm. The voltage can be adjusted between 2.6V (Green), 3.2V (Yellow), and 4.0V (Red) by clicking the button 3 times. The device also uses the color indicator for the battery life: green - 70% or more, yellow - 30% to 70%, and red means less than 30% battery life left. To use the device in the Preheat Mode, tap the button twice and the power button will flash repeatedly while it warms up the cartridge, to deactivate Preheat mode, simply press the button once. If you hold the button continuously the V-Mod will work in the normal mode with the direct output. V-Mod can be charged via the micro USB charging port with the adapter 0.5-1.0A.
