Now the Cube X Kit does have a familiar shape to all of their previous Cube Mods, but this one doesn't have an internal battery. Instead, it's powered by a single external 18650 battery, and has a max wattage output of 80w. Its actual shape may seem strange at first, but once you have it in your hands, it's incredibly comfortable. The primary reason is that its ergonomically shaped to fit your hands, and there's no sharp edges. The OBS Cube X Mod also has a large 0.96 inch OLED display screen, and is primarily constructed of zinc alloy material.
