The Helve by Asmodus is designed in the USA and was crafted with the users total comfort in mind. The perfectly contoured body is designed to facilitate a great, comfortable vaping experience and the Helve has been engineered to prevent it from being top heavy when equipped with a tank or atomizer. The Helve is powered by 2x 18650 batteries (not included) that "pop-out" of the bottom of the Mod when the hatch button is pressed giving the battery compartment and replacement functions a feel that resembles changing the clip of a pistol. This device utilizes the latest revised version of the GX120 chip which features all IC components built in the USA. The all new dual chip set has been updated with hyper power saving capabilities which will elongate the users battery life at an average of 15 - 30% times longer than the typical dual battery mod. A second chip built into the Helve helps with heat dissipation and boost's the overall efficiency of the device.
