“Mini” really fits this product, as it is smaller than the palm of your hand! What a punch it packs, as well! With a 50W capacity, this “grab-n-go” mod features only a fire button with a small screen that gives you a voltage reading. It runs between 3.7-4.0 volts, so it will adjust the wattage on its own according to that voltage range! This mod is perfect for someone that is in need of a small device, or something to bring with them when they are out and about!
